| bus | a parallel connection of conductor that carries data or controlsignals from one unit to another. |
| data bus | a bidirectional pathway linking the CPU to the memory and the i/o devices. |
| adress bus | a pathway that carries data generated by the CPU to the various memory and i/o elements of the computer. |
| PC bus | the bus arcitecture used in the first IBM PC's, originally an 8-bit bus expanded to a 16-bit. |
| ISA | Industry Standard Arcitecture, the 8+16-bit original conductors used in the PC's. |
| EISA | Extended Industry Standard Acitecture, 16 bit ISA was made 32-bit. |
| PCI | Preipheral System Interconnect a high performance32/64 bit bus. |
| Plug an Play | This is a standard that was supossed to make adding peipherals as easy as plugging them in. |
| Bandwith | measurement of a bit per second. |
| Bus master | Any microprocessor that can take control of the bus. |
| Bus Speed | a measurement of MHz. |
| Expansion slot | a type of slot that you can plug memory into. |
| Legacy | describes older computer systems, hardware, and software. |
| FireWire | High speed serial bus, allows for connection of up to 63 devices. Primarily used for digital video. |
| Jumper | a small plug placed over pins (or removed from pins) configuer hardware. |
| I/O address | On PC's, a 3-digit hexadecimal number(2AB,2AO,and so on...)used to identify and signal a pereipheral device like a serial port, parallel port, or sound card. |
| DMA | Direct memory access, special circuitry or a dedicated microprocessor that transfers data from adapters to memory without using the CPU. |
| Adapter | a device that allows one system to connect to and work with another.` |
| Interrupt | Signal the system processor that the adapter card, system hardware, or application software needs attention. |
| AGP | Accelerated graphic port. |
