Introduction 1.1 What is Computer Most people know that a computer is a fast calculator, but it is much more than that. It is a machine that performs fast calculations plus performs burdensome chores such as choosing, copying, moving, comparing, and performing other operations on alphabetic numeric and other symbols which represent data (raw material of information). In other words, a computer is an electronic machine that processes DATA according to the given instruction and program and then provides us with our desired result. It is an electrical device built to recognize and follow a given set of instructions.
