33
answer
contact information and his or her

or publisher of the site. Does the author provide
contact information such as e-mail, phone number, or
a mailing address? Can you determine the author’s
credentials? The more information you have about the
author or publisher of the site and can verify that the
information is true, the easier it will be to determine the
site’s reliability.

(A) It is associated with an educational
answer
institution.
(B) It is an English teacher’s personal

search?
(A) Shakespeare sonnets
Correct
(B) Shakespeare AND sonnets

that contain both of these words.
6.Which of the following statements about search

answer
Search engines and directories are two of the most
commonly used tools for online research. Search
engines search the Web for all documents that contain
keywords you specify and may list thousands of
unordered results. Search engines do not discriminate
between good and bad sites. A directory, on the other
hand, is someone’s attempt to categorize the best
sites available for a given subject or topic.
7.Which of the following statements about metasearch engines is NOT true?
(A) Meta-search engines scan multiple
search engines simultaneously.
Correct

based on the keyword(s) submitted.
(D) Meta-search engines can save time,

exclusively.
A meta-search engine is a type of search engine that
35
scans multiple search engines simultaneously and
provides results based on the keyword(s) submitted.
Though they can save time, meta-search engines rely
on simple keyword searches. Ixquick and Vivísimo are

8.Critically evaluating content on the Web is
important because

answer
There’s no guarantee that what
you’re reading is objective and has
gone through standard fact-checking
and editorial reviews.
(D) printed information is always more
accurate than information found on
the Web.
Unlike libraries, the World Wide Web does not have a
system of organization or an editorial review of online
resources. Anyone can publish just about anything on
the Web and pass it off as an authoritative source. For
this reason, it is important to critically evaluate Web
sources.
9.Which of the following is an example of effective
online searching?
(A) Do a random keyword search on a
search engine of your choice. Then,
quickly browse through all the results
listed and find the ones you think
have the most useful information.
Correct
(B) Formulate research questions, list
answer
possible sources of information,
identify keywords, and begin your
search.
(C) Visit chat rooms and find out what
others are saying about your topic.
(D) Post a question about your topic on
a message board and read all the
36
responses.
Before you begin your search for Web resources, you
should prepare a search plan. The difference between
aimless surfing and a focused search plan can be vital
to your search. Make sure you formulate research
questions, list possible sources of information (if you
know of any), and identify keywords before you begin
your search.

Downloading is the method of getting a file from another computer. The
opposite of downloading a file is uploading a file, where a user sends a file
to another computer.
When on the Internet you are actually downloading, to your computer's hard
disk drive, each page you view. In addition to downloading web pages, when
53
downloading software such as a software update or patch you are also
downloading a file to the computer.
When downloading a file it is important that you remember where you
copied the file to on your hard disk drive. If this is not known you may have
a difficult time locating the file and running it to have it do its specific task.
Several downloads can be found through our download page.
08/2000 - What is a cookie?

Cooking software
Web site
Internet information file
Hacker file
Cookie, in short, is an Internet File. The complete definition of a computer
Cookie is simply an HTTP header that consists of a text-only string that gets
entered into the memory of your browser. This string contains the domain,
path, lifetime, and value of a variable that you set. If the lifetime of this
variable is longer than the time the user spends at your site, then this string
is saved to file for future reference.
Many believe that computer cookies are dangerous and are a privacy
concern. However, cookies are stored on your computer hard disk drive and
only accessible by the page it was created or the user of the computer.
Some examples of how computer cookies can help you are:
1. Store on your hard disk drive your personal information and
preferences for a web site such as an Internet Store. This information
can only be accessed by that store and is used to help direct you faster
to places that most interest you.
2. Store information about your preferences for a start page. If you have
a customized start page which contains information such as local
weather and news, this information is placed on the web page by
looking at information from a cookie.
The above are just a few good examples of computer cookies, to help
understand what exactly they are used for.
07/2000 - What is degauss?
1. Attachment for CPU
2. Creating magnetic media
54
3. Erasing magnetic media
4. Medical software
Term derived from Johann Gauss who was a mathematician that studied and
worked with electro-magnetic fields. Degauss is a method of erasing
magnetic media and the removal of remnants of previously recorded signals.
The degauss process is achieved by passing magnetic media through a
magnet field more powerful than the media itself in order to rearrange the
magnetic particles.
Update: Michael B., a visitor of Computer Hope, also indicated that
Degaussing was first used by the British Royal Navy in the 2nd WW. An
electro-magnetic cable was inserted on the inside and around each warship
as a safeguard against magnetic mines. Each time a ship came into harbor it
was degaussed. An electrical current was passed through this cable and the
magnetic field was neutralized, hence the magnetic mine was unemployed.
When degaussing a monitor the degauss demagnetizes the CRT, fixing
possible color impurities. After either the Degauss button is pressed or the
monitor is manually Degaussed, the degaussing circuit will be activated and
then deactivated after a few seconds. Older monitors may not have this
ability; however, handheld monitor degauss can also be used to restore color
impurities. Additional Information on Monitors can be found on our monitor
page.

Computer Viruses cannot be contracted through a computer scanner, not to
be confused with a Virus Scanner. While the hardware scanner may be
inputting data from hard copies or other sources of data, it is impossible for
a virus to be transferred through a scanner as the input is being placed into
an image format. Additional information on computer viruses can be found
at our Virus section.
05/2000 - A CPU stands for what?
1. Central Power Unit
2. Certified Public Unit
55
3. Central Processing Unit
4. Certified Power Unit
The CPU, or the Central Processing Unit, is the brain of the computer and
the single most important chip in the computer. Modern processors contain
millions of transistors which are etched onto a tiny square silicon called a
die, which is about the with of a standard thumb. The CPU performs the
system's calculating and processing. The majority of personal computers
included the Intel processors. Intel released the first processor, the 4004, in
1971. Today, the market is being shared by other companies such as the
popular AMD processor manufactured by the AMD company. Additional
information can be found on our CPU page.
04/2000 - A Cathode Ray Tube is found in what?
1.
2.
3.
4.
CPU
Printer
Monitor
Scanner
A Cathode Ray Tube that is commonly referred to as a CRT is found in a
Computer Monitor. The CRT is the main component and most expensive part
within your computer monitor. Within the CRT are three electron guns: Red,
Green and Blue. Each of these guns streams a steady flow of electrons left to
right for each line of your monitor. As the electrons hit the phosphors on the
CRT, the phosphor will glow certain intensities. As a new line begins, the
guns will then begin at the left and continue right, these guns will repeat
this process sometimes thousands of times, until the screen has been
completely drawn line by line. Once the phosphors on the CRT have been hit
with an electron they will only glow for a short period of time; because of
this, the CRT must be refreshed which means the process will be repeated as
explained above. Additional information on computer Monitors can be found
on our Monitor Page.
03/2000 - What does the term IRQ stand for?
