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]
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.
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 ...
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 ...
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.
The power supply is on the bottom rear. A computer case, also known as a computer chassis, is the enclosure that contains most of the hardware of a personal computer. The components housed inside the case (such as the CPU, motherboard, memory, mass storage devices, power supply unit and various expansion cards) are referred as the internal ...
