Computer cooling. A finned air cooled heatsink with fan clipped onto a CPU, with a smaller passive heatsink without fan in the background. A 3-fan heatsink mounted on a video card to maximize cooling efficiency of the GPU and surrounding components. Commodore 128DCR computer's switch-mode power supply, with a user-installed 60 mm cooling fan.
Power-on self-test. A power-on self-test ( POST) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on. [ 1] POST processes may set the initial state of the device from firmware and detect if any hardware components are non-functional.
At the top of the case is a fan controller. Fan control is the management of the rotational speed of an electric fan. In computers, various types of computer fans are used to provide adequate cooling, and different fan control mechanisms balance their cooling capacities and noise they generate. This is commonly accomplished by the motherboards ...
An embedded controller can have the following tasks: Receiving and processing signals from the keyboard [ 1] and the touchpad (including touchpad disable) Other buttons and switches (e.g., power button, laptop lid switch (received from hall sensor)) [ 2] Controlling access to the A20 line [ 3] Thermal measurement (CPU, GPU, Motherboard) and ...
Arm Ltd. (sells designs only) Amazon (AWS Graviton is ARM-based); Apple Inc. (ARM-based CPUs) Broadcom Inc. (ARM-based, e.g. for Raspberry Pi) Fujitsu (its ARM-based CPU used in top supercomputer, still also sells its SPARC-based servers)
A motherboard (also called mainboard, main circuit board, MB, base board, system board, or, in Apple computers, logic board) is the main printed circuit board (PCB) in general-purpose computers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central ...
Computer hardware. 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. It includes external devices such as a monitor, mouse, keyboard, and speakers. [ 1][ 2]
Input/output. v. t. e. In the context of an operating system, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. [ 1] A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware ...
