ABSTRACT
The entire
universe is now living in the computer age; most of our day to day jobs are
being influenced by the use of computers. It is used increasingly in each and
every field of our life. In the areas of science and technology improvements
cannot be without the use of computers. Hence it has become necessary to have
basic knowledge about computers.
This project
focuses on installation of computer systems and resuscitation of computer
laboratory in the Department of Electrical/Electronic Engineering, Institute of
Technology, Kwara State Polytechnic, Ilorin.

INTRODUCTION TO COMPUTER
1.1.
COMPUTER SYSTEM
Computer is an electronic device
which is capable of receiving information (data) in a particular form and of
performing a sequence of operations in accordance with a predetermined but
variable set of procedural instructions (program) to produce a result in the
form of information or signals [1].
A computer accepts and then processes input data according to the
instruction it is given. The main components of a computer system are Input,
Output, Processing and Storage units as shown in Figure 1.1.
1.2 A BRIEF HISTORY
OF COMPUTER SYSTEM
The computer had its beginning with
a 19th century English mathematics professor named Charles Babbage.He designed
the Analytical Engine and it was this design that the basic framework of the
computers of today is based on. Computers can be classified into three
generations. Each generation lasted for a certain period oftime,and each gave
us either a new and improved computer or an improvement to the existing
computer. The computer generations are:
1.
FIRST GENERATION (1937 – 1946)
In
1937 the first electronic digital computer was built by Dr. John V. Atanasoff and Clifford Berry
[2]. It was called the
Atanasoff-Berry Computer (ABC). In 1943 an electronic computer name the
Colossus was built for the military. Other developments continued until in 1946
the first general– purpose digital computer, the Electronic Numerical
Integrator and Computer (ENIAC) was built. It is said that this computer
weighed 30 tons, and had 18,000 vacuum tubes which was used for processing.
When this computer was turned on for the first time lights dim in sections of
Philadelphia. Computers of this generation could only perform single task, and
they had no operating system.
2.
SECOND GENERATION: 1947 – 1962
This
generation of computers used transistors instead of vacuum tubes which were more
reliable. In 1951 the first computer for commercial use was introduced to the
public; the Universal Automatic Computer (UNIVAC 1) [3]. In 1953 the International Business Machine (IBM) 650 and 700
series computers made their mark in the computer world. During this generation
of computers over 100 computer programming languages were developed, computers
had memory and operating systems. Storage media such as tape and disk were in
use also were printers for output.
3.
THIRD GENERATION: 1963 – PRESENT
The invention of integrated circuit
brought us the third generation of computers [4] With these invention computers became smaller, more powerful
more reliable and they are able to run many different programs at the same
time. In1980 Microsoft Disk Operating System (MS-Dos) was born and in 1981 IBM
introduced the personal computer (PC) for home and office use. Three years
later Apple gave us the Macintosh computer with its icon driven interface and
the 90s gave us Windows operating system.
1.3
CHARACTERISTICS OF COMPUTER
1.
SPEED:
Computer is very fast calculating
device. It can execute basic operations like subtraction, addition,
multiplication and division at a few microseconds. It can move and copy data at
a speed in the order of billion instructions per second.
2.
ACCURACY:
Computer always gives
accurate results. The accuracy of Computer does not go down when they are used
continuously for hours together. It always gives accurate results.
3.
STORAGE CAPACITY:
Computer has a
very large storage capacity. A large volume of information can be stored in the
memory of computer and information can be retrieved correctly when desired.
4.
VERSATILITY:
The working of
computer with different types of data is known as versatility. That means
computer can perform different types of job efficiently. Computer can work with
different type of data and information such as visuals, text, graphics &
video etc. So, versatility is a most important characteristic of computer.
5.
DILLIGENCE:
A Computer can work for long hours
with the same accuracy and speed because it is free from problems of boredom or
lack of concentration.
6.
NO THOUGHTS:
Computers have no
thoughts because they are machine and they are devoid of emotions. They have no
feelings. Since, computers have no thoughts and feelings so they can't make
judgment based on thoughts and feelings.
1.4 LIMITATIONS OF
A COMPUTER
Computer is very intelligent machine
but it also suffers from many limitations such as:
·
Computer cannot do anything unless
they are just programmed to perform a specific task.
·
Computers cannot interpret the data
they generate.
·
Computers cannot detect if the
operator feeds any wrong data to it.
·
Computers cannot decide how they are
to be programmed or provide their own input.
·
Computers cannot implement the
decision that they suggest.
1.5 AIM AND
OBJECTIVES OF THE PROJECT
The primary aim is installation of computer systems and
resuscitation of computer laboratory.
The specific objectives are:
·
To understand the basic interaction
between all the stages involved in computer installation
·
To be able to recognize all
components and drives including hardware and software
·
To have deep understanding on how to
troubleshoot a computer system when it develops technical faults
·
To know how to carried out system
configurations and software installation
·
Finally, to build up a computer
system for Electrical-Electronic computer laboratory.
1.6 METHODOLOGY
A computer installation can be assembled through various means but
in this project the computer installation was assembled by selecting all the
materials components needed for the assembling and software system
installation. All the hardware components selected for the project are bought
including the tools and software needed.
After the
assembling of the system unit then operating system was loaded on the computer
system and the operating system installed on the computer is Window XP because
of it functionality and easy compatibility with other application software,
likewise, on antivirus software was installed on each of the computer.
