CHAPTER ONE
INTRODUCTION
1.1 BACKGROUND OF THE STUDY
In the past, people have become used to machine built to perform a specific purpose, for instance, the typewriter can produce neat work, a musical instrument can produce a certain type of sound e.t.c. However computer does all these things, often more efficiently than the specific purpose machine mentioned above, hence we say that computer is a general purpose machine.
Computer is probably best introduced on the basis of its purpose, which is data processing. Processing of data into information. Data is known as the raw materials on which a computer operates. There are facts recorded about people’s daily activities such as in business, science, education, government and other forms of organized human activities or endeavours. When some appropriate structures have been applied to data it becomes information.
