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. These programs enable computers to perform a wide range of tasks. The term computer system may refer to a nominally ...
The Kenbak-1, released in early 1971, is considered by the Computer History Museum to be the world's first personal computer. It was designed and invented by John Blankenbaker of Kenbak Corporation in 1970, and was first sold in early 1971. Unlike a modern personal computer, the Kenbak-1 was built of small-scale integrated circuits, and did not ...
Computer science is the study of computation, information, and automation. [1] [2] [3] Computer science spans theoretical disciplines (such as algorithms, theory of computation, and information theory) to applied disciplines (including the design and implementation of hardware and software ).

A public computer (or public access computer) is any of various computers available in public areas. Some places where public computers may be available are libraries, schools, or dedicated facilities run by government. Public computers share similar hardware and software components to personal computers, however, the role and function of a ...
A central processing unit ( CPU ), also called a central processor, main processor, or just processor, is the most important processor in a given computer. [1] [2] Its electronic circuitry executes instructions of a computer program, such as arithmetic, logic, controlling, and input/output (I/O) operations. [3] [4] [5] This role contrasts with ...
Computer engineering. Computer engineering ( CoE or CpE) is a branch of computer science and electronic engineering that integrates several fields of computer science and electronic engineering required to develop computer hardware and software. [1] Computer engineering is referred to as computer science and engineering at some universities.
Use. Computer networks extend interpersonal communications by electronic means with various technologies, such as email, instant messaging, online chat, voice and video telephone calls, and video conferencing. A network allows sharing of network and computing resources.
Data General Nova, serial number 1, on display at the Computer History Museum. A minicomputer, or colloquially mini, is a type of smaller general-purpose computer developed in the mid-1960s [1] [2] and sold at a much lower price than mainframe [3] and mid-size computers from IBM and its direct competitors. In a 1970 survey, The New York Times ...
