COMPUTER MAIN
PARTS
Name: Rafael Eduardo Barrios Navas
SOFTWARE
 This software is known as the
logical equipment or
software of a computer
system, comprising all the
necessary software
components that make it
possible to perform specific
tasks, as opposed to the
physical components that
are called hardware.
OPERATING SYSTEM
 An operating system (OS or often
-of English Operating System- OS)
is a program or set of programs of
a computer system that manages
hardware resources and provides
services to application programs
running in privileged mode
regarding the other (although
some of it may run in user space).
DEVICE DRIVER
 A device driver or device
driver (in English: device
driver or just driver) is a
computer program that
allows the operating
system to interact with a
peripheral, abstracting
the hardware and
providing an interface
(possibly standardized) to
use device
SERVER
 A server is a running
application (software)
capable of meeting the
requests from a client and
return a response
accordingly. The servers
can run on any type of
computer, including
computers dedicated to
which they are individually
known as "server".
COMPILER
 A compiler is a computer
program that translates a
program written in a
programming language to
another language
programación. Usually second
language is machine language,
but can also be an
intermediate code (bytecode),
or just text. This translation
process is called compilation.
WATERFALL MODEL
 The pure waterfall model
hardly used as it is, because
this would imply a prior and
thorough knowledge of the
requirements, the nonvolatility of the same (or
stiffness) and subsequent
steps free of errors; this could
only apply to a few small
systems to develop.
EVOLUTIONARY MODELS
 The software evolves over time.
User requirements and product
often change as it develops. The
dates of market and competition
make it not possible to expect to
bring to market an absolutely
complete product, so it is
advisable to introduce a limited
functional version somehow to
ease competitive pressures.
