Also known as general-purpose computer, computers

A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (computation). Modern digital electronic computers can perform generic sets of operations known as programs, which enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the hardware, operating system, software, and peripheral equipment needed and used for full operation, or to a group of computers that are linked and function together, such as a computer network or computer cluster.

OverviewAI-generated

A computer is an invention and machine that functions as a computing platform, information processor, and data terminal equipment. It utilizes electronics, mechanical energy, and electricity. The subject includes parts such as input-output devices, software, computer hardware, and computer keyboards. It is distinct from calculators, central processing units, computer monitors, and computing.

The computer was discovered or invented by Charles Babbage in 1945. It is studied by computer science and exhibits characteristics including computer configuration, class of computers, computer performance, and computer interface. The topic is categorized under Computers and is maintained by WikiProject Computer Science, WikiProject Computing, WikiProject Software, and WikiProject Engineering. It appears on focus lists for Wikipedia articles and has social media followers totaling 175367.

A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (computation). Modern digital electronic computers can perform generic sets of operations known as programs, which enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the hardware, operating system, software, and peripheral equipment needed and used for full operation, or to a group of computers that are linked and function together, such as a computer network or computer cluster.

A broad range of industrial and consumer products use computers as control systems, including simple special-purpose devices like microwave ovens and remote controls, and factory devices like industrial robots. Computers are at the core of general-purpose devices such as personal computers and mobile devices such as smartphones. Computers power the Internet, which links billions of computers and users.
