| Question | Answer |
|---|---|
| active cooling | Cooling that has moving parts, such as a fan. |
| ARM | Advanced RISC machine, a type of RISC processor that is used in many mobile devices because it uses less power and generates less heat than CISC processors. |
| BIOS | Basic input/output system, a 16-bit chip that stores fixed instructions for startup on older motherboards. Also refers to the configuration utility for setting BIOS options. |
| Bluetooth | A short-range RF connection method for attaching wireless peripherals to PCs and mobile devices. |
| CPU | Central processing unit, the main processing chip on a motherboard. It accepts numbers and instructions for performing calculations on them, and delivers the calculated results. |
| device driver | Software that translates between the language of the OS and the language of the device hardware. |
| DIMM | Dual inline memory module, RAM mounted on a small rectangular circuit board that fits into a motherboard slot. |
| display adapter | A video card, or an equivalent chip built into a motherboard, that communicates between the operating system and the display. |
| DisplayPort | A high-speed digital port used to connect some monitors to a PC. |
| DVI | Digital Visual Interface, one of the early digital video ports that was used as an alternative to VGA before HDMI became popular. |
| firmware | Software stored on a chip on a circuit board. |
| FireWire | A now-obsolete high-speed connector that was used in some digital cameras, video recorders, and external hard drives. |
| GPU | Graphics processing unit, a processor dedicated to math calculations involving the display. |
| heat sink | A type of passive cooling that consists of a metal block that wicks away the heat from a hot surface and spreads it out to dissipate it. |
| HDMI | High-definition multimedia interface, a port suitable for connecting a monitor to a PC. |
| IoT | Internet of Things, embedded computers in ordinary household items such as appliances, thermostats, and doorbells. |
| Mini-DP | Mini Display Port, a port used to connect some monitors to a PC. |
| motherboard | A large circuit board that serves as a central gathering point for all the other components in a PC or server. |
| passive cooling | Cooling that involves no moving parts, such as a heat sink. |
| PCIe | Peripheral component interface express, a modern slot type for connecting video cards and other expansion cards in a motherboard. |
| Plug-and-Play | The technology that enables an OS to detect a newly connected device, assign system resources to it, and install an appropriate driver for it. |
| RAM | Random access memory, the main memory used to run a computer. |
| RF | Radio frequency, referring to any of several wireless technologies including Wi-Fi and Bluetooth as well as custom point-to-point wireless connections. |
| RJ-11 | A jack used to connect to a land-line telephone system. |
| RJ-45 | A jack used to connect an Ethernet network cable to a PC, a printer, or a network device such as a switch or router. |
| scanner | A device that digitized hard-copy images. It works like a copier, but instead of outputting to another piece of paper, it outputs to a computer file. |
| SD card | Secure Digital card, a memory-based storage card used for storage in digital cameras and some other small computing devices. |
| server | A powerful computer designed to assist multiple clients with various tasks over a network. |
| Thunderbolt | A modern high-speed interface that uses USB-C connectors. |
| UEFI | Unified extensible firmware interface, a 32-bit chip that stores fixed instructions for startup on newer motherboards. Also refers to the configuration utility for setting UEFI options. |
| USB port | Universal Serial Bus, a standard port for connecting external devices to a PC. Types include USB-A, USB-B, and USB-C. |
| VGA | Video Graphics Array, a port suitable for connecting an older monitor to a PC. |
| workstation | A high-end desktop PC that has advanced components to support certain processor-intensive activities. |
