Computers are human made electronic machines that perform tasks or calculations according to a set of instructions, or given programs. The first fully electronic computer machine was introduced in the 1940s, which were huge machines that required teams of people to operate. Compared to those early machines, today's computers are amazing. Not only are they thousands of times faster, they can fit on your desk, on your lap, or even in your pocket.

Basic Concept: A computer is an electronic device that manipulates information, or data. It has the ability to store, retrieve, and process data.

There are several definitions are available for the computers but the most common definition may be as follow: A computer is an electronic device that manipulates information, or data. It has the ability to store, retrieve, and process data.
