Advanced Technology extended - a motherboard form factor specification developed by Intel in 1995 to improve on previous DE factor standards like the AT form factor.
Accelerated Graphics Port - a high-speed point-to-point channel for attaching a video card to a computer's motherboard, primarily to assist in the acceleration of 3D computer graphics.
A small, fast local memory that transparently buffers access to a larger but slower or more distant/higher latency memory or storage device, organised into cache lines. Automatically translates accesses to the underlying resources address space to locations in the cache.
The process of keeping data in multiple caches synchronised in a multi-processorshared memory system, also required when DMA modifies the underlying memory.
Not finding data in a local cache, requiring use of the cache policy to allocate and fill this data, and possibly performing evicting other data to make room.
in modern usage, a synonym for main memory, dating back from the pre-semiconductor-chip times when the dominant main memory technology was magnetic core memory.
Computer chassis, cabinet, box, tower, enclosure, housing, system unit or simply case - the enclosure that contains most of the components of a computer (usually excluding the display, keyboard and mouse).
a generic term that refers to a high-performance input/output (I/O) architecture that is implemented in various forms on a number of computer architectures, especially on mainframe computers.
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]
(Direct Access Storage Device) A mainframe terminology introduced by IBM denoting secondary storage with random access, typically (arrays of) hard disk drives.
(dual in-line memory module);A series of dynamic random-access memory integrated circuits. These modules are mounted on a printed circuit board and designed for use in personal computers, workstations and servers.
DisplayPort is a digital display interface developed by the Video Electronics Standards Association (VESA). The interface is primarily used to connect a video source to a display device such as a computer monitor, though it can also be used to transmit audio, USB, and other forms of data.
a cache where each physical address may only be mapped to one cache line, indexed using the low bits of the address. Simple but highly prone to allocation conflicts.
(Digital Video Disc or Digital Versatile Disc) - an optical compact disc - of the same dimensions as compact discs (CDs), but store more than six times as much data.
Digital Visual Interface (DVI) is a video display interface developed by the Digital Display Working Group (DDWG). The digital interface is used to connect a video source to a display device, such as a computer monitor.
(Dynamic random-access memory) - a type of random-access memory that stores each bit of data in a separate capacitor within an integrated circuit and which must be periodically refreshed to retain the stored data.
dual issue
refers to a superscalar pipeline capable of executing 2 instructions simultaneously.
a printed circuit board that can be inserted into an electrical connector, or expansion slot on a computer motherboard, backplane or riser card to add functionality to a computer system via the expansion bus. An expansion bus is a computer bus which moves information between the internal hardware of a
computer system (including the CPU and RAM) and peripheral devices. It is a collection of wires and protocols that allows for the expansion of a computer.
a data storage medium that is composed of a disk of thin, flexible ("floppy") magnetic storage medium encased in a square or rectangular plastic shell.
(High-Definition Multimedia Interface) - a compact interface for transferring encrypted uncompressed digital audio and video data to a device such as a computer monitor, video projector or digital television.
powerful computer used mainly by large organizations for bulk data processing such as census, industry and consumer statistics, enterprise resource planning, and financial transaction processing.
the central printed circuit board (PCB) in many modern computers which holds many of the crucial components of the system, while providing connectors for other peripherals.[5]
a layer of hardware-level instructions involved in the implementation of higher level machine code instructions in many computers and other processors.
Any general-purpose computer whose size, capabilities, and original sales price make it useful for individuals, and which is intended to be operated directly by an end user, with no intervening computer operator.
Converts mains AC to low-voltage regulated DC power for the internal components of a 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 mains voltage.
A peripheral which produces a text or graphics of documents stored in electronic form, usually on physical print media such as paper or transparencies.
(Redundant Array of Independent Disks) - data storage schemes that can divide and replicate data across multiple hard disk drives in order to increase reliability, allow faster access, or both.
Random-access memory - a form of computer data storage that allows data items to be accessed (read or written) in almost the same amount of time irrespective of the physical location of data inside the memory. RAM contains multiplexing and demultiplexing circuitry to connect the data lines to the addressed storage for reading or writing the entry. Usually more than one bit of storage is accessed by the same address, and RAM devices often have multiple data lines and are said to be '8-bit' or '16-bit' etc. devices. In today's technology, random-access memory takes the form of integrated circuits.
(or solid-state disk or electronic disk) a data storage device that uses integrated circuit assemblies as memory to store data persistently. It is also referred to as a solid-state disk, but it contains neither an actual disk nor a drive motor to spin a disk.
Static random-access memory - a type of semiconductormemory that uses bistable latching circuitry to store each bit. The term static differentiates it from DRAM which must be periodically refreshed.
an internal expansion card that facilitates economical input and output of audio signals to and from a computer under control of computer programs. It is also referred to as an audio card.
a high-speed, high-capacity alternative to the 90 mm (3.5 in), 1.44 MB floppy disk. The SuperDisk hardware was created by 3M's storage products group Imation in 1997.
Also known as a touchpad;[7] a pointing device consisting of specialized surface that can translate the motion and position of a user's fingers or a stylus to a relative position on a screen.
also referred to as a graphics card and several other names, a video card is an expansion card which generates a feed of output images to a display (such as a computer monitor).
