| Question | Answer |
|---|---|
| Accelerated Graphics Port (AGP) | A 32 bit wide bus standard developed specifically for video cards that includes AGP 1x, 2x, 3x, 4x, and 8x standards. AGP has been replaced by the PCI Express standards. |
| PCIe | The latest evolution of PCI, which is not backward-compatible with earlier PCI slots and cards. PCIe slots come in several sizes including PCIe, PCIe x1, PCIe x4, PCIe x8, and PCIe x16 |
| Audio/Modem riser (AMR) | a specification for a small slot on a motherboard to accommodate an audio or modem riser card. |
| communication and Network riser | a specification for a small expansion slot on a motherboard that accommodates a small audio, modem, or network riser card. |
| Dual Inline Package (DIP) Switch | A switch on a circuit board or other device that can be set to on or off to hold configuration or setup information. |
| Front Panel Header | A group of pins on a motherboard that connect to wires that are connected to the front panel of the computer case. |
| Heat Sink | a piece of metal, with cooling fins, that can be attached to or mounted on an integrated chip (such as the CPU) to dissipate hear. |
| Land Grip Array (LGA) | A computer network that covers only a small area, usually within one building. |
| North Bridge | that portion of the chipset hub that connects faster I/O buses (for example, AGP buses) to the system bus. Compare to the south bridge. |
| South Bridge | that portion of the chipset hub that connects slower I/O buses (for example, a PCI bus) to the system bus. Compare to the north bridge. |
| Pin Grid Array | A feature of a CPU socket whereby the pins are aligned in uniform rows around the socket. |
| Staggered Pin Grid Array (SPGA) | A feature of a CPU socket whereby the pins are staggered over the socket in order to squeeze more pins into a small space. |
| Standoffs | Round plastic or metal pegs that separate the motherboard from the case, so that components on the back of the motherboard do not touch the case. |
| System Clock | A line on a bus that is dedicated to timing the activities of components connected to it. The system clock provides a continuous pulse that other devices use to time themselves. |
| Zero Insertion Force Sockets | A socket that uses a small lever to apply even force when you install the microchip into the socket. |
