Function (computer programming) In computer programming, a function, subprogram, procedure, method, routine or subroutine is a callable unit [1] of software logic that has a well-defined interface and behavior and can be invoked multiple times. Callable units provide a powerful programming tool. [2] The primary purpose is to allow for the ...
IBM 2741, a widely emulated computer terminal in the 1960s and 1970s. (keyboard/printer) A computer terminal is an electronic or electromechanical hardware device that can be used for entering data into, and transcribing [1] data from, a computer or a computing system. [2] Most early computers only had a front panel to input or display bits and ...
Computer operator. A computer operator is a role in IT which oversees the running of computer systems, ensuring that the machines, and computers are running properly. [1] The job of a computer operator as defined by the United States Bureau of Labor Statistics is to "monitor and control ... and respond to ... enter commands ... set controls on ...
A single-board computer ( SBC) is a complete computer built on a single circuit board, with microprocessor (s), memory, input/output (I/O) and other features required of a functional computer. Single-board computers are commonly made as demonstration or development systems, for educational systems, or for use as embedded computer controllers.
Library (computing) Illustration of an application which uses libvorbisfile to play an Ogg Vorbis file. In computer science, a library is a collection of read-only resources that is leveraged during software development to implement a computer program . Historically, a library consisted of subroutines (generally called functions today).
Computer vision is an interdisciplinary field that deals with how computers can be made to gain high-level understanding from digital images or videos. From the perspective of engineering, it seeks to automate tasks that the human visual system can do.
Processor (computing) In computing and computer science, a processor or processing unit is an electrical component ( digital circuit) that performs operations on an external data source, usually memory or some other data stream. [1] It typically takes the form of a microprocessor, which can be implemented on a single or a few tightly integrated ...
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 ...
