| Bus | a parrallel connection of conductor that carries data or controlsignals from one unit to another |
| Data Bus | a bidriectional pathway linking the CPU to the memory and the I/O devices |
| Address Bus | A pthhway that carries data generated by the CPU to the variuos memory and I/O elements of the computer |
| PC Bus | The bus arcitecture used in the first IBM PC's, originally a 8 bit bus expanded to an 16 bit |
| ISA | Industry standard Acritecture, the 8 +16 bit original connectors used in the PC's |
| EISA | Extended Industry Standard Arcitecture 16 bit ISA was made 32 bit |
| PCI | Preihepreal System Interconnect a high preformance 32/64 bit bus |
| Plug and Play (PnP) | This is a standard that was supposed to make adding perihepreals as easy as pluging 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 olders computer systems, hardware, and software |
| Firewire | Hight speed serial bus, allows for connection of u to 63 devices primarily used for digital video |
| Jumper | A small plug placed over pins (or removed form pins) to configure hardware |
| I/O Address | On PC's, a 3 digit hexadecimal number (2AB, 2AO, and so on) used to identify and signal a periphereal device like a serial port, parrallel port, or sound card |
| DMA | Direct Memory Access. Specialized circutry or a dedicated microprocessor that tansfers data from adapters to memory without using the CPU |
| Adapter | A device that allows one system to connect to and work with another |
| Interupt | A signal that gets the Attention of the CPU and is usually generated when I/O is required |
| AGP | Accelerated Graphics Port, Arciecture that is Based on the PCI arcitecture and is designed sepcifically to speed p 3D graphics |
