| A | B |
| 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 archetectures used in the first IBM PC's, originally an 8-bit bus expanded to a 16-bit bus |
| ISA | Industry standard architecture, used for 8-16 bit expansion cards |
| EISA | EISA is extended ISA to carry 32 bit cards |
| PCI | periphial system interconnect a high performance 32/64 bit bus |
| PnP | Makes adding peripherals easy as pluging in and using |
| Bandwidth | A measure of amount of data that can pass through any device |
| Bus Master | processor unit that can take control of the system busses on a computer |
| Bus Speed | Ameasurement of how fast data can pass through a bus |
| Expansion Slot | any slot that you can plug a pheripheal into |
| Legacy | Older computer device that is non PnP |
| FireWire | High speed serial buss that alows up to 63 devices |
| Adapter | a device that allows one system to connect to and work with another. converts one set of signals to another |
| Interupt | a signal that gets the cup's attetion, usualy generated when an I/O is needed |
| Jumper | A small plug placed over pins to configure hardware |
| DMA | Direct Memory Access, specialized to use a microprocssor instad on main processor |
| I/O adress | A 3 digit hexadecimal number used to identify and signal a device |
| AGP | Accelerated Graphics Port. Architecture that is basedon the PCI architecture and is designed specifically to speed up 3D graphics |
