What is computer?

A computer is an electronic device which is use to store data and processing data, and give useful information.

A computer is a machine that can be taught to work in a mathematical or logical sequence automatically with a computer program. Modern computers have the ability to follow general operating sets, called programs. These programs enable computers to perform extremely complex tasks. A "complete" computer including Hardware, operating system (basic software), and security equipment required and used for "complete" operation can be called a computer program. This term can be used for a group of computers connected and working together, especially a computer network or set of computers.

Computers are used as controls for a variety of industrial and consumer devices. This includes easy devices with special purpose like microwave ovens and remote controls, manufactory devices like industrial robots and laptop-assisted construction, as well as standard purpose devices such as personal computers and mobile devices such as smartphones. The Internet works on computers and connects hundreds of millions of other computers with their users.
