Inside a gaming case during gameplay. 360° photograph. A full tower case. Accessories shown include: a fan controller, a DVD burner, and a USB memory card reader.. Cases can come in many different sizes and shapes, which are usually determined by the form factor of the motherboard since it is physically the largest hardware component in most computers. Consequently, personal computer form ...
A disk enclosure is a specialized casing designed to hold and power hard disk drives or solid state drives while providing a mechanism to allow them to communicate to one or more separate computers. Drive enclosures provide power to the drives therein and convert the data sent across their native data bus into a format usable by an external ...
A transparent plastic housing around an electronic device. In engineering, a housing or enclosure is a container, a protective exterior (e.g. shell) or an enclosing structural element (e.g. chassis or exoskeleton) designed to enable easier handling, provide attachment points for internal mechanisms (e.g. mounting brackets for electrical components, cables and pipings), maintain cleanliness of ...
Any data input device that reads data from a card-shaped storage medium such as a memory card. [1] [2] [3] channel I/O 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. chipset. Also chip set.
Caching works by prefetching data before the CPU needs it, reducing latency. [55] [56] If the data the CPU needs is not in the cache, it can be accessed from main memory. [55] Cache memory is typically SRAM, while the main memory is typically DRAM. [27] RAM is volatile, meaning its contents will disappear if the computer powers down. [57]
A mid-tower computer case from c. 2011. In personal computing, a tower unit, or simply a tower, is a form factor of desktop computer case whose height is much greater than its width, thus having the appearance of an upstanding tower block, as opposed to a traditional "pizza box" computer case whose width is greater than its height and appears lying flat.
Data exists in three states: data at rest, data in transit and data in use. Data within a computer, in most cases, moves as parallel data. Data moving to or from a computer, in most cases, moves as serial data. Data sourced from an analog device, such as a temperature sensor, may be converted to digital using an analog-to-digital converter.
In computing, a word is any processor design's natural unit of data. A word is a fixed-sized datum handled as a unit by the instruction set or the hardware of the processor. . The number of bits or digits [a] in a word (the word size, word width, or word length) is an important characteristic of any specific processor design or computer architect
