| Bus | A parrallel collection or conductors that carry data or control signals from one unit to another |
| Data Bus | A bi-directional pathway linking the cpu to memory and I/O devices |
| Address Bus | A path way that carries data generated by the CPU to the various memory and I/O elements of the computer |
| PC Bus | The bus architectures used in the first IBM, PC's originally a 8-bit bus expanded to a 16-bit bus |
| ISA | Industry standard architecture The 8- and 16-bit original connectors used in PC's. |
| EISA | Extended industry standard architecture, 16-bit ISA was extended to 32 bits and they called it EISA |
| PCI | Peripheral system interconnect A high-performance 3/64 - bit bus. |
| Pnp | This is standard that was supposed to make adding peripherals to your system as easy as plugging them in and using them |
| Bandwith | A measure in some amount of its per second, of the amount of data that can be sent over a particular cable, interface or bus |
| Bus Master | Any class of microprocessor unit the ability to take control of the system bus's of a computer |
| Bus speed | A measurement usually in MHZ, of how many times data can be transferred over the bus per second. |
| Expansion Slot | Refers to any type of slot in a computer that you can plug an expansion card into, generally its limited to ISA, EISA, PCI and PCMIA |
| Adapter | A device that allows one system to connect to and work with another. |
| Interrupt | A signal that gets the attention of the CPU and is usually generated when I/O is required. |
| Jumper | Fits on two metal connectors. It provides an electrical connection between the two wires to enable a semi-permanent hardware configuration. |
| DMA | Direct Memory Access. The ability of certain intelligent, high-speed I/O devices to perform data transfers themselves, with the help of the DMA controller. |
| I/O Address | On PCs, a three-digit hexadecimal number used to identify and signal a peripheral device like a serial port, parallel port, or sound card. |
| AGP | Accelerated Graphics Port. Architecture that is based on the PCI architecture and is designed specifically to speed up 3D graphix. |
| Legacy | Describes older computer systems, hardware, software. |
| FireWire | Highspeed serial bus allows for connection of up to 63 devices primarily used for digital video |
