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. By retaining
the instruction and DATA in the form of electrical images it carries out
the instructions one by one and works on ( processes ) the DATA to
produce useful results, often called output or information. Computer
output can be Reports, Charts, or even moving images.
