Практические занятия – 4 часа Внеаудиторная самостоятельная работа – 3 часа Аудиторная работа 1. Read the text. A computer is a machine with an intricate network of electronic circuits that operate switches or magnetize tiny metal cores. The switches, like the cores, are capable of being in one or two possible states that is, on or off; magnetized or demagnetized. The machine is capable of storing and manipulating numbers, letters, and symbols. The basic idea of a computer is that we can make the machine do what we want by inputting signals that turn certain switches on and turn others off, or magnetize or do not magnetize the cores. The basic job of computers is processing of information. For this reason computers can be defined as devices which accept information in the form of instructions, called a program, and characters, called data, perform mathematical and/or logical operations on the information, and then supply results of these operations. The program, or part of it, which tells the computers what to do and the data, which provide the information needed to solve the problem, are kept inside the computer in a place called memory. It is considered that computers have many remarkable powers. However most computers, whether large or small, have three basic capabilities. First, computers have circuits for performing arithmetic operations, such as: addition, subtraction, division, multiplication and exponentiation. Second, computers have a means of communicating with the user. After all, if we couldn’t feed information in and get results back, these machines wouldn’t be of much use. Some of the most common methods of inputting information are to use terminals, diskettes, disks and magnetic tapes. The computer’s input device (a disk drive or tape drive) reads the information into the computer. For outputting information two common devices used are: a printer, printing the new information on paper, and a cathode-ray-tube display, which shows the results on a TV-like screen. Third, computers have circuits which can make decisions. The kinds of decisions which computer circuits can make are not of the type: “Who would win the war between two countries?” or “Who is the richest person in the world?” unfortunately, the computer can only decide three things, namely: Is one number less than another? Are two numbers equal? and, Is one number greater than another? A computer can solve a series of problems and make thousands of logical decisions without becoming tired. It can find the solution to a problem in a fraction of the time it takes a human being to do the job. 2.

SOME FACTS FROM THE HISTORY OF COMPUTERS Практические занятия – 12 часов Внеаудиторная самостоятельная работа – 12 часов Аудиторная работа 1. Read the text: The history of automatic computers is believed to have started with Charles Babbage, an English scientist. It was he who suggested that a machine for mathematical computations could be made. When Charles Babbage, a professor of Cambridge University, invented the first calculating machine in 1812, he could hardly have imagined the situation we find ourselves in today. Charles Babbage was born in Devonshire, England in 1792. He didn't receive a good education, but he taught himself mathematics so well, that when he went to Cambridge he found that he knew mathematics better than his tutor. Babbage was outstanding among his contemporaries because he was the first to insist on the practical application of science and mathematics. In 1812 he was sitting in his room, working with the table of logarithms, which he knew to be full of mistakes, when an idea of computing all tabular functions by machinery occurred to him. Babbage constructed a small working model which was demonstrated in 1822. The Royal Society supported the project and Babbage was promised a subsidy. In 1833 he began to think of building a machine which was, in fact, the first universal digital computer. Babbage devoted the rest of his life to an attempt to develop 6 it. He had to finance the whole of the work himself and he was only able to finish part of the machine, though he prepared thousands of detailed drawings from which it could be made. Charles Babbage wrote more than eighty books and papers, but he was misunderstood by his contemporaries and died a disappointed man in 1871. He tried to solve a series of problems required the united efforts of two generations of engineers by himself and with his own resources. After his death his son continued his work and built a part of an arithmetic unit, which printed out its results directly on paper. 2.

DATA PROCESSING AND DATA PROCESSING SYSTEMS Практические занятия – 12 часов Внеаудиторная самостоятельная работа – 12 часов Аудиторная работа 1. Read the text: The necessary data are processed by a computer to become useful information. In fact this is the definition of data processing. Data are a collection of facts – unor8 ganized but able to be organized into useful information. Processing is a series of actions or operations that convert inputs into outputs. When it is spoken of data processing, the input is data, and the output is useful information. So, data processing can be defined as a series of actions or operations that converts data into useful information. The term data processing system includes the resources that are used to accomplish the processing of data. There are four types of resources: people, materials, facilities, and equipment. People provide input to computers, operate them, and use their output. Materials, such as boxes of paper and printer ribbons, are consumed in great quantity. Facilities are required to house the computer equipment, people and materials. The need for converting facts into useful information is not a phenomenon of modern life. Throughout history, and even prehistory, people have found it necessary to sort data into forms that were easier to understand. For example, the ancient Egyptians recorded the ebb and flow of the Nile River and used this information to predict yearly crop yields. Today computers convert data about land and water into recommendations to farmers on crop planting. Mechanical aids to computation were developed and improved upon in Europe, Asia, and America throughout the 17th, 18th, and 19th centuries. Modern computers are marvels of an electronics technology that continues to produce smaller, cheaper, and more powerful components. Basic data processing operations. Five basic operations are characteristic of all data processing systems: inputting, storing, processing, outputting, and controlling. They are defined as follows. Inputting is the process of entering data, which are collected facts, into a data processing system. Storing is saving data or information so that they are available for initial or for additional processing. Processing represents performing arithmetic or logical operations on data in order to convert them into useful information. Outputting is the process of producing useful information, such as a printed report or visual display. Controlling is the directing the manner and sequence in which all of the above operations are performed. Data storage hierarchy. It is know that data, once entered, are organized and stored in successfully more comprehensive hierarchy. The general grouping of any data storage hierarchy are as follows. Characters, which are all written language symbols: letters, numbers, and special symbols. Data elements, which are meaningful collections of related characters. Data elements are also called data items or fields. Records, which are collections of related data elements. Files, which are collections of related records. A set of related files is called a data base or a data bank. 2.

A COMPUTER SYSTEM Практические занятия – 12 часов Внеаудиторная самостоятельная работа – 12 часов Аудиторная работа 1. Read the text: A computer system is a collection of components that work together to process. The purpose of a computer system is to make it as easy as possible for you to use computer to solve problems. A functioning computer system combines hardware elements with software elements. The hardware elements are the mechanical device, the system, the machinery and the electronics. The software elements are the programs written for the system. Collectively these components provide a complete computer system. Usually, a computer system requires three basic hardware items: the central processor unit, which performs all data processing; a terminal device, which helps users to communicate with their computer system and a memory storing programs and data. These three devices are the required hardware components of any computer sys11 tem. Computer system includes many other devices: printer, scanner and a modem. These computer devices called hardware. A set of instructions telling a computer what to do is a program. Programs are usually written in a Programming language like Pascal. Programs you are dealing with are organized into files. Applications are programs for specific tasks. Applications include: database software, spreadsheets calculations, wordprocessing on a word processor. To make hardware and software function, a computer needs an operation system program. Some operation systems require users to type in commands to tell the computer what to do. Many computers use a graphical interface or point-and-click interface such as Windows. Some interfaces allow plug-and-play, the possibility of connecting new hardware the computer without having to adjust or configure the system to take the new hardware into account: the interface program recognizes the hardware automatically. 2.

HARDWARE, SOFTWARE, AND FIRMWARE Практические занятия – 12 часов Внеаудиторная самостоятельная работа – 12 часов Аудиторная работа 1. Read the text: The units that are visible in any computer are the physical components of a data processing system, or hardware. Thus, the input, storage, processing and control devices are hardware. Not visible is the software – the set of computer programs, procedures, and associated documentation that make possible the effective operation of 13 the computer system. Software programs are of two types: systems software and applications software. Systems software are the programs designed to control the operation of a computer system. They do not solve specific problems. They are written to assist people in the use of the computer system by performing tasks, such as controlling all of the operations required, to move data into and out of a computer and all of the steps in executing an application program. The person who prepares systems software is referred to as a systems programmer. Systems programmers are highly trained specialists and important members of the architectural team. Applications software are the programs written to solve specific problems (applications), such as payroll, inventory control, and investment analysis. The word program usually refers to an application program, and the word programmer is usually a person who prepares applications software. Often programs, particularly systems software, are stored in an area of memory not used for applications software. These protected programs are stored in an area of memory called read-only memory (ROM), which can be read from but not written on. Firmware is a term that is commonly used to describe certain programs that are stored in ROM. Firmware often refers to a sequence of instructions (software) that is substituted for hardware. For example, in an instance where cost is more important than performance, the computer system architect might decide not to use special electronic circuits (hardware) to multiply two numbers, but instead write instructions (software) to cause the machine to accomplish the same function by repeated use of circuits already designed to perform addition. 2.

Give a brief summary of the text. Самостоятельная работа 4. Translate the text using the dictionary if necessary: In order to use computers effectively to solve problems in our environment, computer systems are devised. A "system" implies a good mixture of integrated parts working together to form a useful whole. Computer system may be discussed in two parts. 14 The first part is hardware – the physical, electronic, and electromechanical devices that are thought of and recognized as "computers". The second part is software – the programs that control and coordinate the activities of the computer hardware and that direct the processing of data. The basic components of computer hardware are joined together in a computer system. The centerpiece is called the computer, the processor, or usually the central processing unit (CPU). The term "computer" usually refers to those parts of the hardware in which calculations and other data manipulations are performed, and to the internal memory in which data and instructions are stored during the actual execution of programs. The various peripherals which include input and/or output devices, various secondary memory devices, and so on, are attached to the CPU. Computer software can be divided into two very broad categories – system software and applications software. The former is often simply referred to as "systems". These, when brought into internal memory, direct the computer to perform tasks. The latter may be provided along with the hardware by a systems supplier as part of a computer product designed to answer a specific need in certain areas. These complete hardware/software products are called turnkey systems. The success or failure of any computer system depends on the skill with which the hardware and software components are selected and blended. A poorly chosen system can be a monstrosity incapable of performing the tasks for which it was originally acquired. 5. Ask as many questions as possible to the text. 6. Use the necessary preposition in the sentences: 1. A "system" implies a good mixture … integrated parts working together. 2. Computer system may be discussed … two parts. 3. Hardware is the physical, electronic, and electromechanical devices that are thought … and recognized as "computers". 4. The basic components … computer hardware are joined together … a computer system. 5. Applications software may be provided along … the hardware … a systems supplier as part … a computer product designed to answer a specific need … certain areas. 7. Make up sentences using the word combinations: To use effectively, to work together, to form a useful whole, electronic devices, to coordinate the activities, to join together in a system, input and output devices, memory devices, a computer product, to answer a specific need, perform the tasks. 15 Unit 6. COMPUTER OPERATIONS Практические занятия – 6 часов Внеаудиторная самостоятельная работа – 8 часов Аудиторная работа 1. Read the text: Much of the processing computers can be divided into two general types of operation. Arithmetic operations are computations with numbers such as addition, subtraction, and other mathematical procedures. Early computers performed mostly arithmetic operations, which gave the false impression that only engineers and scientists could benefit from computers. Of equal importance is the computers ability to compare two values to determine if one is larger than, smaller than, or equal to the other. This is called a logical operation. The comparison may take place between numbers, letters, sounds, or even drawings. The processing of the computer is based on the computer’s ability to perform logical and arithmetic operations. Instructions must be given to the computer to tell it how to process the data it receives and the format needed for output and storage. The ability to follow the program sets computers apart from most tools. However, new tools ranging from typewriters to microwave ovens have embedded computers, or, built-in computers. As embedded computer can accept data to use several options in its program, but the program itself cannot be changed. This makes these devices flexible and convenient but not the embedded computers itself. Types of data. With the advent of new computer applications and hardware, the definition of data has expanded to include many types. Numeric data consists of numbers and decimal points, as well as the plus (+) and minus (-) signs. Both arithmetic operations and logical operations are performed on numeric data. This means that numbers can be used for calculations as well as sorted and compared to each other. Text, or textual data, can contain any combination of letters, numbers and special characters. Sometimes textual data is known as alphanumeric data. Various forms of data that we can hear and see make up audio-visual data. The computer can produce sounds, music and even human voice. It can also accept audio information as an input. Data can also take form of drawings and video sequences. Physical data is captured from the environment. For example, light, temperature and pressure are all types of physical data. In many large buildings, computer systems process several kinds of physical data to regulate operations. Computers can set off security alarms, control temperature and humidity, or turn lights on and off, all in response to physical data. These applications increase people’s safety and save the time and money. 2.

PRINTERS Практические занятия – 6 часов Внеаудиторная самостоятельная работа – 6 часов Аудиторная работа 1. Read the text: Printers provide information in a permanent, human-readable form. They are the most commonly used output devices and are components of almost all computer systems. Printers vary greatly in performance and design. We will classify printers as character printers, line printers and page printers in order to identify three different approaches to printing, each with a different speed range. In addition, printers can be described as either impact or non-impact. Printers that use electromechanical mechanisms that cause hammers to strike against a ribbon and the paper are called impact printers. Non-impact printers do not hit or impact a ribbon to print. Character printers print only one character at a time. A typewriter is an example of a character printer. Character printers are the type used with literally all microcomputers as well as on computers of all sizes whenever the printing requirements are not large. Character printers may be of several types. A letter-quality printer is a character printer which produces output of typewriter quality. Letter-quality printers typically have speeds ranging from 10 to 50 characters per second. Dot-matrix printers form each character as a pattern of dots. These printers have a lower quality of 18 type but are generally faster printers than the letter-quality printers – in the range of 50 to 200 characters per second. One of the newest types of character printer is the ink-jet printer. It sprays small drops of ink onto paper to form printed characters. The ink has a high iron content, which is affected by magnetic fields of the printer. These magnetic fields cause the ink to take the shape of a character as the ink approaches the paper. Line printers are electromechanical machines used for high-volume paper output on most computer systems. Their printing speeds are such that to an observer they appear to be printing a line at a time. They are impact printers. The speeds of line printers vary from 100 to 2500 lines per minute. Line printers have been designed to use many different types of printing mechanisms. Two of the most common print mechanisms are the drum and the chain. Drum printers use a solid, cylindrical drum, rotating at a rapid speed. Speeds of drum printers vary from 200 to over 2000 lines per minute. Chain printers have their character set on a rapidly rotating chain called a print chain. Speeds of chain printers range from 400 to 2400 lines per minute. Page printers are high-speed non-impact printers. Their printing rates are so high that output appears to emerge from the printer a page at a time. A variety of techniques are used in the design of page printers. These techniques, called electrophotographic techniques, have developed from the paper copier technology. Laser-beam printers use a combination of laser beam and electrophotographic techniques to create printer output at a rate equal to 18000 lines per minute. 2.

Практические занятия – 12 часов Внеаудиторная самостоятельная работа – 12 часов Аудиторная работа 1. Read the text: Wherever you were, whatever you read, see or hear you can meet information about Internet. Whether you worked in the sphere of education or business, whether you were an employee of some official body, whether you worked with a computer you were probably once or twice asked: “What is your address in the Internet?” So what is Internet? Why has this global network suddenly appeared? How many people use Internet? In what directions does Internet develop? Answers to these questions allow experts to develop this extremely important communication system. There are three stages of computer development. 1. The era of the “Black box” (1939 – 1970). That time computers represented the huge weight of electronic lamps, transistors or integrated circuits. They also filled huge black metal boxes. If you smoked or raised voice, they wheezed and stopped. IBM firm manufactured the majority of them. 2. The era of personal computers (1970 – 1990). The invention of microcircuits and new operational systems meant that computers of cheaper and smaller sizes could perform the larger amount of work faster. Miniaturization and improvement of program maintenance have given computers at disposal of small business and families. By the end of this period the majority of people used programs of Microsoft firm. 3. The era of the WorldNet (1992). The beginning of Internet was necessary for the defensive industry, and for investigators of the academic laboratories and computer communication network. There were dozens of experts in the USA, in the UK, and Norway who were true explorers of Internet. The new communication facility became popular when operators started to send messages to each other to exchange new ideas and to discuss general scientific problems. It was e-mail. Internet is the largest communication network in the world. Recently some sources have been approved and now Internet connects more than 40000 various networks in more than one hundred countries. Imagine, that over 5 million main computers participate in Internet and service 40 million users all over the world. However, it is very difficult to define real number of users to say how widely Internet is distributed. Nobody operates this network. It has no management establishing, the instructions for use, and allocated authority to introduce them. Internet extends faster and faster. It is easier to speak about how Internet has grown for years from the moment of its appearance than to name the exact amount of its users. Internet is frequently considered by beginners as a big information “dump”*. But to help them with 21 huge amount of facts there are various search systems, thematic sites etc. There are also such collectors of the information as encyclopedias. Due to** them, you do not need to search for the necessary information on the sites. It is only 91 necessary to find the thematic encyclopedia interesting to you and the address taken from Internet, and to read everything on the given theme. In the network there are both universal and specialized encyclopedias. As an example it is possible to take Cyril and Mephody’s site. Here you can find the encyclopedia and, besides 25 thematic sections. Search is conducted according to the thematic word or a word collocation. As a result you receive references to the thematic sections and then the articles in the encyclopedia. For example, at input of a word “mouse” articles from sections “Animals” and “Computers” will be offered to you. Besides on a site you have an opportunity to take part in the conference. At your disposal there is a board of announcements***, the information on news, weather, currency. It is possible to say that it is the best in Russia Internet encyclopedia. All its articles are absolutely exclusive. Other example is Britannica. It is huge universal English-speaking encyclopedia. It is submitted without reductions. The encyclopedia consists of two parts: “Macromedia” and “Micromedia”. First, you receive the brief information from “Micromedia”, and then if it is necessary, from “Macromedia”. Numerous references to the articles from books and magazines allow you to receive the exhaustive information on your question.

GENERATIONS OF COMPUTER Практические занятия – 12 часов Внеаудиторная самостоятельная работа – 12 часов Аудиторная работа 1. Read the text: First Generation Computers (1954-59) were rather bulky in size, required large amounts of air conditioning and repair time also. The important advantages over earlier machines were speed of calculation, use of the stored program, the ability to apply logical decisions to calculated results, various types of input and output equipment, magnetic tape, paper tape, ability to modify its own program, etc. Second Generation Computers (1959-64) replaced the vacuum tubes with the tiny transistor, thus requiring less power and offering greater reliability. Highspeed card readers and printers were introduced. Symbolic programming was replacing machine language programming during this period. Random access devices were introduced. Repair and maintenance time was greatly reduced. Third Generation Computers (1964-70) were characterized by advanced miniaturization and refinement of computer components. Greater compilers, newer and faster methods of input and output, optical scanners, magnetic ink character readers, data transmission over long distances, displays on video tubes, multiprogramming, tremendous storage capacities, remote terminals with access to central computers – innovations introduced during this period. Fourth Generation Computers (1970-1980) featured many changes in all sectors of the computer field. The concept of “Virtual Storage” increased the main storage capabilities of computers by allowing a computer to directly access outside storage devices as though they were part of main storage. The minicomputer made spectacular advances during this period. 23 Fifth Generation. In the 1980s very large scale integration (VISI), in which hundreds of thousands of transistors were placed on a single chip, became more and more common. The “shrinking” trend continued with the introduction of personal computers (PCs) used by individuals. By the late 1980s some personal computers were run by microprocessors that could process about 4000000 instructions per second. The new generation, the so-called “fifth” generation is using new technologies with new programming languages capable of amazing feats in the area of artificial intelligence. 2.

MICROPROCESSOR AS A CPU Практические занятия – 12 часов Внеаудиторная самостоятельная работа – 12 часов Аудиторная работа 1. Read the text: We can also view the microprocessor as a primary component of a computer. Traditionally, the computer is represented in block of components: Memory, Input, Output, and the Сentral Processor Unit (CPU), which consists of Arithmetic/Logic Unit (ALU) and Control Unit. The CPU contains various registers to store data, the ALU to perform arithmetic and logical operations, instruction decoders, counters, and control lines. The CPU reads instructions from the memory and performs the task specified. It communicates with input/output devices either to accept or to send data. These devices are also known as peripherals. The CPU is the primary and central player in communicating with devices such as memory, input, and output. However, the timing of the communication process is controlled by the group of circuits called the control unit. In the 1960s, the CPU was designed with discrete component on various boards. With the advent of the integrated circuit technology, it became possible to build the CPU on a single chip; this came to be known as microprocessor. 2. Choose the right answer to the questions given below: 1. What component of a computer can be viewed as primary? a) the ALU b) the memory c) the CPU 2. Where does the CPU store data? a) in registers b) in counters c) in instruction decoders 3. What devices are called peripherals? a) the memory b) integrated circuits c) input/output devices 25 3. Look through the text; find the necessary information to prove the title. EVOLUTION IN SIZE Computers come in all sizes. Large ones are called mainframes. The mainframes have been around the longest, and there are a lot of them, especially in larger organizations. The most powerful computers, however, are called supercomputers. The supercomputers are so powerful that they are found in only a few of the larger business organizations. Supercomputers most often are used for scientific calculations. The recent trend has not been to larger computers, but to smaller ones. In the 1970 s, this trend got its start with minicomputers, or minis. These computers were smaller than the mainframes but, in many cases, outperformed the larger units. The minis were received so well that computer manufacturers produced even smaller units – called microcomputers or micros. Most of the microcomputer’s main circuitry is in the form of a small silicon chip, smaller than your fingernail. The chip is called a microprocessor. You also hear terms like “small business computer” and “personal computer”. A small business computer is a mini or micro that is usually found in smaller firms and provides the computational support. Самостоятельная работа 4. Read the text: BILL GATES Everyone has heard of Bill Gates, one of the richest and most successful people in the world. Microsoft, the business he started with a friend in 1975, has become the world’s largest computer software company, and Gates was the world’s youngest billionaire at the age of 31. His full name is William Henry Gates III, and he was born on 28th October, 1955, in Seatle, USA. At school, Bill soon showed that he was very intelligent, and especially good at Maths and Science. His parents decided to send him to Lakeside, the private school where he first began to use computers. 13-yearold Bill Gates and his schoolfriend Paul Allen were soon spending all their time writing programs and learning about computers instead of doing their schoolwork! After finishing school in 1973, Bill went to Harvard, America’s most famous university. The next year, he and Paul Allen wrote an operating program for the Altair, one of the world’s first microcomputers. The two friends started Microsoft in 1975, and Gates left Harvard. Before long, Microsoft was a major business success. Since then, the company has continued to grow, producing most of the world’s leading PC software. One reason for his success is that Gates has always been very ambitious and hardworking. This has not left him much time for a normal personal life, but in 1994 he married Melinda French, a Microsoft employee, and in 1995 he wrote a best-selling book, “the Road Ahead”. Bill has mixed feelings about spending so much time running Microsoft. “There are a lot of experiences I haven’t had, but I do like my job,” he says. When he does find time to relax, he likes puzzles, golf and reading about science. For such a rich person, his life is simple, and he spends little on himself and his family. When it comes to helping others, though, Gates is very 26 generous*. He has already given huge amounts of money to charity and says that he plans to give away almost all of his wealth** when he retires***. Notes: *generous – великодушный **wealth – богатство ***retire – уйти на пенсию, отойти от дел 5. Answer the questions: 1. What is Bill Gates’s full name? 2. What have he and Paul Allen done together? 3. Why has Gates been so successful? 4. What does he do in his free time? 5. What does he plan to do with all his money? 6. Use the information of the text to talk about Bill Gates. Unit 11. USES OF THE WEB Практические занятия – 6 часов Внеаудиторная самостоятельная работа – 8 часов Аудиторная работа 1. Read the text: The fact that the Web is being widely used for multiple purposes is without question. But before overviewing its benefits it is worth considering one fact that became crucial event for it. The question is about a new mode of presenting information. Before, over the Internet and other wide area networks, the text has been the main mode of presentation. The Web changed that. Now the information could be presented in graphical format, complete with font choices and incorporated drawings, photographs, tables and other multimedia elements. These graphical elements offered different kinds of information and information providers were able to search precisely the element. The result of these innovations is that the Web’s capabilities are increasing, its information becomes more comprehensible too. Of course the work has to be done right and those who care about their information perfectly know how to do it. One of the first to use Web was science. Dissemination of research and scientific discoveries have always been one of the purposes of the Internet and of the Web project at CERN in Switzerland. Today the Web is used as a tool of exchanging scientific information as it has been considered to do. But perhaps more important is that the Web is used to make research discoveries available to the general public, most of this information being presented so that it becomes as easy understandable as possible. Publicly funded research agencies are interested in making their work known to the public, in finding new ways to place information. Booklets and pamphlets distrib27 uted through mailing are expensive and usually ignored. The Web is the best way out of the problem. Now on a well-designed HTML* page a user can demonstrate its activities graphically and these pages can be updated inexpensively and frequently. Providing services for clients as to technical documents, software patches and answers to frequently asked questions is another benefit of the Web using. Customers with a Web access are able to take care of their own information needs without resorting to the help of supplier’s support staff. Many other services of this kind are likely to be developed for making the Web more friendly to users. For example, the possibility of Web based tutorials are offering step-by-step procedures for installation a new piece of equipment or for programming your VCR**. Well designed, this service is certain to be better than a usual, tech support phone call because it shows, rather than tells, the customer what to do and how to do. It should be noted that these Web applications are not a one-way link. Customers need to know that they are not forgotten and that there is a place where they can learn from the experiences of other customers. It becomes possible due to HTML forms to provide a feedback and to answer questions on products. The latter is especially valuable in products ordering. Now there are many who are interested in this service rendered by the Web, and it is despite of the discussion as to the Web’s security for credit cards use. Why is the Web shopping so attractive? Imagine you can find a variety of products ranging from the flowers to books for your music CDs, and all this by browsing through the Web and without leaving your home. Moreover, unlike home shopping on TV, you needn’t sit through the other products that are of no use for you in order to find the item you have been looking for. Shopping on the Web is like walking into a shopping mall (by the way, “mall” is the name given to many Web offerings). There is only one thing for the customer to do: click on the shop you want, turn on the online graphic to see a picture of the chosen product and address to the other forms page to do the ordering. Such services are expected to be more often used. At last, such spiritual part of human activity as creative arts is not aside from the Web pages. People in creative arts are often regarded as adherent to traditional forms of arts and resistant to new technologies. However, it would be an erroneous opinion, because throughout the history people of arts have always been among the first to adopt new technologies to their work. Such examples as printing press or MIDI*** witness it. Therefore, it is quite natural that the artists consider WWW to be a new medium suitable for presenting their works and for linking up with their colleagues. Now we see galleries of new visual art to appear online or the presentation of artworks that are asked to be evaluated by the Web users. As to creative writings, it becomes frequent on the Web and includes interactive stories, illustrated texts, and even Web-based drama. The Web attracts artists by an inexpensive way of presenting their work and a build-in global audience. This is something about which artists could only dream before. 28 Of course, there are some arts that couldn’t be placed on Web sites. But it may be a matter of future. Notes: *HTML (Hypertext Markup Language) – язык НТМ (стандартный язык, используемый для создания страниц WWW). **VCR (Video Cassette Recorder) – видеомагнитофон ***MIDI (Musical Instruments Digital Interface) – цифровой интерфейс музыкальных инструментов (стандарт сопряжения электронных музыкальных инструментов с компьютером и программным обеспечением) 2.

COMPUTER-INTAGRATED MANUFACTURING Практические занятия – 10 часов Внеаудиторная самостоятельная работа – 8 часов Аудиторная работа 1. Read the text: Since about 1970 there has been a growing trend in manufacturing firms toward the use of computers to perform many of the functions related to design and production. The technology associated with this trend is called CAD/CAM, for computeraided design and computer-aided manufacturing. Today it is widely recognized that the scope of computer applications must extend beyond design and production to include the business functions of the firm. The name given to this more comprehensive use of computers is computer-integrated manufacturing (CIM). CAD/CAM is based on the capability of a computer system to process, store, and display large amounts of data representing part and product specifications. For mechanical products, the data represent graphic models of the components; for electrical products, they represent circuit information; and so forth. CAD/CAM technology has been applied in many industries, including machined components, electronic products, and equipment design and fabrication for chemical processing. CAD/CAM involves not only the automation of the manufacturing operations but also the automation of elements in the entire design-and-manufacturing procedure. Computer-aided design (CAD) makes use of computer systems to assist in the creation modification, analysis, and optimization of a design. The designer, working with CAD system rather than the traditional drafting board, creates the lines and surfaces that form the object (product, part, structure, etc.) and stores this model in the computer database. By invoking the appropriate CAD software, the designer can perform various analyses on the object, such as heat transfer calculations. The final object design is developed as adjustments are made on the basis of these analyses. Once the design procedure has been completed, the computer-aided design system can generate the detailed drawings required to make the object. 30 Computer-aided manufacturing (CAD) involves the use of computer systems to assist in the planning, control, and management of production operations. This is accomplished by either direct or indirect connections between the computer and production operations. In the case of the direct connection, the computer is used to monitor or control the processes in the factory. Computer process monitoring involves the collection of data from the factory, the analysis of the data, and the communication of process-performing results to plant management. These measures increase the efficiency of plant operations. Computer process control entails the use of the computer system to execute control actions to operate the plant automatically, as described above. Indirect connections between the computer system and the process involve applications in which the computer supports the production operations without actually monitoring or controlling them. These applications include planning and management functions that can be performed by the computer (or by humans working with the computer) more efficiently than by humans alone. Examples of these functions are planning the step-by-step processes for product, part programming in numerical control, and scheduling the production operations in the factory. Computer-integrated manufacturing includes all the engineering functions of CAD/CAM and the business functions of the firm as well. These business functions include order entry, cost accounting, employee time records and payroll, and customer billing. In an ideal CIM system, computer technology is applied to all the operational and information-processing functions of the company, from customer orders through design and production (CAD/CAM) to product shipment and customer service. The scope of the computer system includes all activities that are concerned with manufacturing. In many ways, CIM represents the highest level of automation in manufacturing. 2.

Самостоятельная работа 5. Read the text and translate it paying attention to the definition of the term “computer graphics”. COMPUTER GRAPHICS A) Computer graphics means the use of computers to produce pictorial images. The images produced can be printed documents or animated motion pictures, but the term computer graphics refers particularly to images displayed on a monitor. Monitor can display graphic as well as alphanumeric data. A computer-graphics system basically 104 consists of a computer to store and manipulate images, a monitor, various input and output devices, and a graphics software package – i.e., a program that enables a computer to process graphic images by means of mathematical language. A computer displays images on the phosphor-coated surface of a graphics display screen by means of an electron beam that sweeps the screen many times each second. Those portions of the screen energized by the beam emit light, and changes in the intensity of the beam determine their brightness and hue. The brightness of the resulting image fades quickly, however, and must be continuously “refreshed” by the beam, typically 85 times per second. B) Graphics programs enable a user to draw, color, shade, and manipulate an image on a display screen with the use of a mouse, a pressure-sensitive tablet, or a light pen. Preexisting images on paper can be scanned into the computer through the use of scanners, digitizers, pattern-recognition devices, or digital cameras. Frames of images on videotape also can be entered into a computer. Various output devices have been developed as well; special programs send digital data from the computer’s memory to an image setter or film recorder, which records the image sequence on video film. The computer can also generate hard copy by means of plotters and laser or dotmatrix printers. Pictures are stored and processed in a computer’s memory by either of two methods: raster graphics and vector graphics. Raster-type graphics maintain an image as a matrix of independently controlled dots, while vector graphics maintain it as a collection of points, lines, and arcs. Raster graphics are now the dominant computer graphics technology. Raster graphics create uniform colored areas and distinct patterns and allow precise manipulation. Raster graphics emerged in the early 1970s and had largely displaced vector systems by the ‘90s. Vector-graphics technology which was developed in the mid-1960s and had been widely used until it was supplanted by raster graphics. Its application is now largely 32 restricted to highly linear work in computer-aided design and architectural drafting, and even this is performed on raster-type screen with the vector-type screens with the vectors converted into dots. Computer graphics has found widespread use in printing, product design and manufacturing, scientific research, and entertainment since 1960s. 6. Name the components of a computer-graphics system. Unit 13. WHAT IS A TROJAN HORSE AND WHAT THREAT DOES IT POSE? Практические занятия – 12 часов Внеаудиторная самостоятельная работа – 12 часов Аудиторная работа 1. Read the text: Since "Trojan Horses" (or Backdoors) have been in the news just recently, the term probably sounds familiar to you. But perhaps you're not quite sure what a Trojan Horse is and what damage it is capable of doing to your system. Trojan Horses, of which there are now more than one thousand in circulation (including modifications and variants), are a relatively new and probably the most dangerous strain of viruses that have appeared in recent times. They also threaten to overwhelm systems that only run anti-virus applications and firewalls as a means of combating the threat. Today's Trojans as they are commonly referred to as have now attained such a degree of sophistication that they pose a real threat to any user who hasn't taken adequate precautions to protect their data. The name "Trojan Horse" derives itself from a page in Greek history when the Greeks had laid siege to the fortified city of Troy for over ten years. Their spy, a Greek called Sinon offered the Trojans a gift in the form of a wooden horse and convinced them that by accepting it, they would become invincible. The horse though was hollow and was occupied by a contingent of Greek soldiers. When they emerged in the dead of night and opened the city gates, the Greeks swarmed in, slaughtered its citizens and subsequently pillaged, burned and laid waste to the city. In the IT environment, the Trojan Horse acts as a means of entering the victim's computer undetected and then allowing a remote user unrestricted access to any data stored on the user's hard disk drive whenever he or she goes online. In this way, the user gets burned and like the unfortunate citizens of Troy, may only discover that fact when it is too late. These types of viruses were originally designed as a means of self-expression by gifted programmers and did little more than to cause the system to lock up, behave abnormally in a specific way or perhaps cause loss of data on the user's machine. 33 2. Increase your knowledge of computer viruses; What is a virus? In 1983, researcher Fred Cohen defined a computer virus as “a program that can “infect” other programs by modifying them to include a version of itself.” This means that viruses copy themselves, usually by encryption* or by mutating** slightly each time they copy. There are several types of viruses, but the ones that are the most dangerous are designed to corrupt your computer or software programs. Viruses can range from an irritating*** message flashing on your computer screen to eliminating data on your hard drive. Viruses often use your computer's internal clock as a trigger. Some of the most popular dates used are Friday the 13th and famous birthdays. It is important to remember that viruses are dangerous only if you execute (start) an infected program. There are three main kinds of viruses. Each kind is based on the way the virus spreads. 1. Boot Sector Viruses - These viruses attach themselves to floppy disks and then copy themselves into the boot sector of your hard drive. (The boot sector is the set of instructions your computer uses when it starts up.) When you start your computer (or reboot it; your hard drive gets infected. You can get boot sector viruses only from an infected floppy disk. You cannot get one from sharing files or executing programs. This type of virus is becoming less common because today's computers do not require a boot disk to start, but they can still be found on disks that contain other types of files. One of the most common boot sector viruses is called "Monkey”, also known as "Stoned". 2. Program Viruses - These viruses (also known as traditional file viruses) attach themselves to programs' executable files. They can infect any file that your computer 113 runs when it launches a program. When you start a program that contains a virus, the virus usually loads into your computer's memory. When the virus is in your computer's memory, it can infect any other program that is started. Program viruses that have circulated recently are "SKA" and "Loveletter." 3. Macro Viruses - These viruses attach themselves to templates that are used to create documents or spreadsheets. Once a template is infected, every document or spreadsheet you open using that program also will become infected. Macro viruses are widespread because they infect commonly used office applications and spread between PCs and Macintoshes. Macro viruses include “Concept”, “Melissa”, and “Have a Nice Day”. Notes: *encryption – кодирование **mutating – мутация ***irritating – раздражающий 3. Say what you have learned about: a) boot sector viruses b) program viruses c) macro viruses 34 4. Compare this subdivision with the subdivision of viruses in the main text. Самостоятельная работа 5. Read the text below and say what form the text is written in: a) a story b) recommendations PREVENTING A VIRUS • Purchase and install antivirus software, and update it frequently. Virus software can be obtained from a variety of sources. • Most antivirus packages have a component that loads at computer startup and monitors files as you use them. • Scan every file you receive: files from friends, programs from the Internet, email attachments, and even shrink-wrapped software. Do not configure your e-mail program to launch your word processing program automatically when it receives an attachment. • Scan every file you download from the Web before you install or read it. • Be very careful about putting floppy disks from unknown sources into your computer. Be especially careful if the disk has been shared by several people. The more computers that have used the disk the more likely that it could contain a virus. • Back up all your data files on a regular basis. • Make sure that you have the original disks or CD-ROMs for all your software. 6. What recommendation would you follow? 7. Topics for discussion. 1. Different terms used for “virus”. 2. The problem of computer viruses. 3. Means of avoiding catching a virus. Unit 14. COMPUTERS IN SCIENCE Практические занятия – 18 часов Внеаудиторная самостоятельная работа – 18 часов Аудиторная работа 1. Read the text: Computers are perhaps the most useful tools ever invented by mankind. In this, the era of computers, they are used to count our votes, figure our bank accounts, help plan new buildings and bridges, guide our astronauts through space and assist management in its everyday decisions. The dynamic introduction of the computer has changed man's information needs entirely. Man has developed methods of compiling and analyzing large quantities of 35 data with a minimum amount of human intervention. Technological advances in all fields have been dynamic and extensive. The methods of applying data processing systems to information needs are boundless. With each new application, data processing systems can be used to help man increase his productivity and advance civilization further. It's a giant step forward in man's utilization of science and knowledge as a means of progress. What can computers do for the scientist? Now weather scientists are able to work out astronomical number of calculations for predicting weather changes. They are even working on a mathematic model of the world's weather that may someday enable us to make accurate weather forecasts a year or more ahead of time. In medicine computers are helping researchers test drugs by extrapolating the information gained in limited trials, so that large scale tests will not only be safer, but will yield far more useful information. Computers are helping doctors make diagnoses by winnowing down the information a doctor has to go through to arrive at a valid conclusion. Biochemists are using computers as a sort of mathematical microscope, in delving into the secret of the living cell; they have found a physical limit to the information they can obtain with their instruments. By using computers they have already obtained and are beginning to construct an accurate picture of the giant molecules that are the building blocks of all living things. In astronomy, computers, of course, serve as computational workhorses, figuring out the exact positions and orbits of planets, stars and other heavenly bodies. With the growing importance of radio telescope, computers have been especially valuable in analyzing the patterns of signal received from outer space, separating the meaningful signals from the electronic roar of background "noise" that accompanies them. Space technology would be almost unthinkable without the power of the computer. This is an area of science that requires the combined knowledge of all other sciences – physics, chemistry, thermodynamics, electronics, mathematics, even psychology. Only computers can bring this large amount of information under control to make it serve our efforts. The achievements of computers in the fields of space exploration, weather reporting, medical, research and other areas of scientific study have been fantastic. The tremendous storage capacities and rapid processing of data have produced the valuable information necessary for research in the unknown areas of science. Scientific research has moved into the foreground of human activity. In both the pure and applied sciences, computers are being used to multiply man's thinking power – and to multiply the time he can spend thinking. 2. Answer the following questions. 1. How is our era characterized in the text? 2. What are computers used for in everyday life? 3. How do computers help researchers in medicine? 4. What are biochemists using computers for? 5. What do computers serve in astronomy for? 36 3. Name the sciences where computers are very useful tools. 4. Agree or disagree to the following statements. 1. The computer has changed men’s information needs entirely. 2. Computers help scientists in all fields of knowledge. 3. Computers will be able to work without a man. 4.

Read the text: Apple Computers may not have ever been considered as the state of art in Artificial Intelligence, but a second look should be given. Not only are today's PCs becoming more powerful but AI influence is showing up in them. From Macros to Voice Recognition technology, PCs are becoming our talking buddies. Who else would go surfing with you on short notice- even if it is the net. Who else would care to tell you that you have a business appointment scheduled at 8:35 and 28 seconds and would notify you about it every minute till you told it to shut up. Even with all the abuse we give today's PCs they still plug away to make us happy. We use PCs more not because they do more or are faster but because they are getting so much easier to use. And their ease of use comes from their use of AI. Speech Recognition. You tell the computer to do what you want without it having to learn your voice. This implication of AI in Personal computers is still very crude but it does work. 37 Script recognition. Cursive or Print can be recognized by notepad sized devices. With the pen that accompanies your silicon note pad you can write a little note to yourself which magically changes into computer text if desired. Your computer can read your handwriting. If it can't read it though – perhaps in the future, you can correct it by dictating your letters instead. Your computer does faster what you could do more tediously. You have taught the computer to do something only by doing it once. In businesses, many times applications are upgraded. But the files must be converted. All of the businesses records but be changed into the new software's type. Macros save the work of conversion of hundreds of files by a human by teaching the computer to mimic the actions of the programmer thus teaching the computer a task that it can repeat whenever ordered to do so. AI is all around us. Don't think the change will be harder on us because AI has been developed to make our lives easier. 2. Translate the text and say what Apples are meant by the author. 3. Answer the questions. 1. What are Apple computers able to recognize? 2. What programs are used for it? 4. Topics for discussion. 1. AI technologies of today. 2.
