Computer History: General Knowledge of Computer! India’s first 

In the history of computers a computer can be described with great simplicity as a device that performs routine operations. Such a definition is a mathematical process that allows one to perform tasks such as approximations and triangulations that are not usually thought of as mathematical.

For example, we need to walk around a room and many complex equations are needed. The computer also serves as a guide for making reports, such as arbitrating a room to balance a checkbook.
