A computer is an electronic device that inputs data and executes the data thereon. Early computers were calculators that had/had no storage capacity. Abacus, Napier's bones, Adding Machine, Jacquard's Loom, Difference Engine, and Analytical Engine are the popular computers that were used in the early days. The computer executes the user's instructions and yields the desired output. A computer system has four components: an input device, a processing device, a storage device, an output device. The input devices offer ways of communicating with the computer. Processing devices store data for retrieval and processing. Storage devices are used for data storage. Computer output devices, such as to monitor display output. Computers can be divided into different categories: supercomputers, mainframe computers, minicomputers, and microcomputers. Supercomputers are used for jobs that take up massive calculating amounts, such as weather forecasting, engineering design. Mainframe computers are used primarily in the banking and finance sectors etc. Minicomputers are used primarily in departmental systems, online bookings, etc.. Microcomputers are used primarily in the offices and as personal computers. Today knowledge of computers is both a necessity as a subject as well as a general experience of life.
