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.
Computer hardware. PDP-11 CPU board. Computer hardware comprises 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.
Distributed computing is a field of computer science that studies distributed systems, defined as computer systems whose inter-communicating components are located on different networked computers. [1] [2]
Central processing unit. 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.
Embedded system. An embedded system is a computer system —a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system. [1] [2] It is embedded as part of a complete device often including electrical or electronic hardware and ...
Direct memory access. Direct memory access ( DMA) is a feature of computer systems that allows certain hardware subsystems to access main system memory independently of the central processing unit (CPU). [1]
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 ...
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.
