| Bus | A parallel collection of conductors that carry data or control signals from one unit to another |
| Data Bus | A bidirectional pathway linking the CPU to memory and 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 archetures used in the first IBM PC's, orignally an 8-bit Bus expanded to a 16-bit bus |
| ISA | Industry Standard Archicture. A PC expansion bus used for modems, video, display, speakers, and other perhipals |
| EISA | Extended Industry Standard Archicture. Extends the ISA bus from 16-bit to 32-bits but can still be used to plug in ISA expansion cards |
| PCI | Peripheral system interconnect. A high performance 32/64 bit bus |
| Plug and Play | The ability of a computer to automaticaly defect and configure new hardwear componets when they are pluged in |
| bandwidth | the amount of data that can be sent through a network connection measured in bits per second |
| bus master | Any class of microprocessors unit with the ability to take control of the system buses of a computer |
| bus speed | a mesurement uaslly in MHz of how many times data can be transfered over the bus per second |
| expansion slots | a stock on the motherboard for plugging in on expansion card. the more expansion sloths a computer has the more features can be added |
| Legacy | discribes older computer systems, hardwear, softwear |
| Fire Wire | High speed searal bus alows connection of up to 63 devices primarlery used for digital video |
| Adpter | Device that allows a syatem to connect and work with another |
| Intrupter | a signl that gets the attetion of the CPU |
| Jumper | a small plug placed over pins to configure hardware settings |
| DMA | Directmemmory acess, specializied circutry a dicated microprocessor that transifers data from adapters to memory without using the CPU |
| I/O Adress | on PCs a three diget hexadecimal number used to identify and signal a peripheral device |
| AGP | Acerlated Graphic Port |
