computer is a machine that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming. These programs enable computers to perform an extremely wide range of tasks. A "complete" computer including the hardware, the operating system (main software), and peripheral equipment required and used for "full" operation can be referred to as a computer system.Computers are used as control systems for a wide variety of industrial and consumer devices. This includes simple special purpose devices like microwave ovens and remote controls, factory devices such as industrial robots and computer-aided design, and also general purpose devices like personal computers and mobile devices such as smartphones.The speed, power and versatility of computers have been increasing dramatically ever since then, with MOS transistor counts increasing at a rapid pace (as predicted by Moore's law), leading to the Digital Revolution during the late 20th to early 21st centuries.

Conventionally, a modern computer consists of at least one processing element, typically a central processing unit (CPU) in the form of a metal-oxide-semiconductor (MOS) microprocessor, along with some type of computer memory, typically MOS semiconductor memory chips.Input devices (keyboards, mice, joystick, etc.), output devices (monitor screens, printers, etc.), and input/output devices that perform both functions (e.g., the 2000s-era touchscreen). Peripheral devices allow information to be retrieved from an external source and they enable the result of operations to be saved and retrieved.The Online Etymology Dictionary gives the first attested use of "computer" in the 1640s, meaning "one who calculates"; this is an "agent noun from compute (v.)". The Online Etymology Dictionary states that the use of the term to mean "'calculating machine' (of any type) is from 1897." The Online Etymology Dictionary indicates that the "modern use" of the term, to mean "programmable digital electronic computer" dates from "1945 under this name.Almost every business uses computers nowadays. They can be employed to store and maintain accounts, personnel records, manage projects, track inventory, create presentations and reports. Healthcare continues to be revolutionized by computers. As well as digitized medical information making it easier to store and access patient data, complex information can also be analyzed by software to aid discovery of diagnoses, as well as search for risks of diseases. Computers control lab equipment, heart rate monitors, and blood pressure monitors.Various government departments use computers to improve the quality and efficiency of their services. Examples include city planning, law enforcement, traffic, and tourism.

Computers are now a fact of life. Computers have created a very effective information system to help streamline the management of an organization. This makes it a much needed tool for every business, banking, government, entertainment, daily life, industry, education, and administration. It can be said of all large organizations, whether the department government or private, use a computer for a variety of their daily business and it is the fastest growing industries in the world today. Each organization usually has one or more large computer systems and a number of microcomputer. The system is a great computer for data processing tasks, while many small microcomputer to use as word processing. Computers have become part of our lives is essential.
