| bus | A parralell collection of conductors that carry data or control signals from one unit to another |
| data bus | bidirectional pathway linking the CPU to memory and I/O Devices |
| Address bus | A Pathway that carries data generated by cputo various memory and I/O elements |
| PC bus | the bus architecture used in the first Ibm pc originally an 8 bit |
| ISA | the 8 and 16 bit bus originl conector as in PSA slot modems and sound cards |
| EISA | 16 bit ISA was extended to 32 bits they called it EISA |
| PCI | a high performance 32/64 bit bus |
| Plug and Play (PnP) | adding periferal to system as easy as pluging them in using them |
| bandwith | a measure in some amount of bits per second over a perticuar table |
| bus Master | any class of microprosessor unit with the ability to take control |
| Bus Speed | A measurment usually in of how many times data be transferred over the bus per second |
| expansion slot | refers to any type of slot in a computer that PnP expantion card into |
| Legacy | describes older computer sistems hardware software. |
| Fire Wire (IEEE 1394) | high speed serial bus allows for conection of up to 63 devices primarly used for digital video |
| Adapter | A device that allows one system to conect to and work with another |
| interrupt | a signal that gets the attention of the CPU and is usally generated when I/O is requiered |
| jumper | a jumper fits on two metal connectors. It provides an elctrical conection between two wires to enable a semiperminenthard ware configeration |
| DMA | the Ability of certain intelligent High speed I/O devices to perform data tranfers themselves with the help of the dma controller |
| I/O Address | on PCs a three digit hexadecimal number used to identify and signal a periferal divice like a serial port parrallel port or a sound card |
| AGP | helps speed up the 3 D grafices |
