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.

CHAPTER ONE
- INTRODUCTION TO COMPUTER
- 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.

- 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:
- 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.
- 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.
- 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.
- CHARACTERISTICS OF COMPUTER
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
