Computer hardware. 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]
A technology consisting of computer components and recording media used to retain digital data. It is a core function and fundamental component of computers. [1] device memory. local memory associated with a hardware device such as a graphics processing unit or OpenCL compute device, distinct from main memory.
In computer science and computer engineering, computer architecture is a description of the structure of a computer system made from component parts. [1] It can sometimes be a high-level description that ignores details of the implementation. [2] At a more detailed level, the description may include the instruction set architecture design ...
A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a desktop computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the main voltage.
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.
Electronic components have a number of electrical terminals or leads. These leads connect to other electrical components, often over wire, to create an electronic circuit with a particular function (for example an amplifier, radio receiver, or oscillator). Basic electronic components may be packaged discretely, as arrays or networks of like ...
e. The history of computing hardware covers the developments from early simple devices to aid calculation to modern day computers. The first aids to computation were purely mechanical devices which required the operator to set up the initial values of an elementary arithmetic operation, then manipulate the device to obtain the result.
CPU-Z is more comprehensive in virtually all areas compared to the tools provided in the Windows to identify various hardware components, and thus assists in identifying certain components without the need of opening the case; particularly the core revision and RAM clock rate. It also provides information on the system's GPU.
