PDP-11 CPU board. Computer hardware includes the physical parts of a computer, such as the central processing unit (CPU), random access memory (RAM), motherboard, computer data storage, graphics card, sound card, and computer case.
The Antikythera mechanism is believed to be the earliest known mechanical analog computer, according to Derek J. de Solla Price. [6] It was designed to calculate astronomical positions. It was discovered in 1901 in the Antikythera wreck off the Greek island of Antikythera, between Kythera and Crete, and has been dated to approximately c. 100 ...
The component diagram extends the information given in a component notation element. One way of illustrating a component's provided and required interfaces is through a rectangular compartment attached to the component element. [3]
Various electronic components, with a 15 cm ruler to scale. An electronic component is any basic discrete electronic device or physical entity part of an electronic system used to affect electrons or their associated fields.
Color model, a way of describing how colors can be represented, typically as multiple values or color components; Component (group theory), a quasi-simple subnormal sub-group
The idea of reusable software components was promoted by Douglas McIlroy in his presentation at the NATO Software Engineering Conference of 1968. [6] ( One goal of that conference was to resolve the so-called software crisis of the time.)
Computer engineers typically describe a modern computer's operation in terms of classical electrodynamics.Within these "classical" computers, some components (such as semiconductors and random number generators) may rely on quantum behavior, but these components are not isolated from their environment, so any quantum information quickly decoheres.
