| Bus | A parrellel collection of conductors that carry data or control signal from one unit to the other. |
| Data Bus | a biderectional pathway linking the cpu to memory and i/o devices |
| Address Bus | a pathway that carries data generated the CPU to various memory and I/O elements of a computer. |
| PC bus | the bus architecture first IBM PCs originally an 8-bit bus expanded to a 16-bit bus. |
| ISA | Industry standard architecture 16-bit original connector used PC's, they run at a bus of 8 MHz. |
| EISA | Extended Industry Standard Architecture. 16-bit ISA was extended to 32-bits and called it EISA. |
| PCI | peripheral system interconnect. A high performance 32/64-bit bus. |
| Plug and Play (PnP) | this is a standard that was supposed to make adding peripherals to your computer as easy as plugging them in. |
| Bandwith | A measure in some amount of bits persecond, of amount of data that can be sent over a cable. |
| Bus Master | any class of micro-proccesor units with the ability to make control of the system buses. |
| Bus Speed | A measurement , usually Mhz of how many times a bus data can be transfered over the bus per sec. |
| Expansion Slot | a type of slot that you can plug and expansion card into. |
| Legacy | any device that does not plug/play they have a static configuration. |
| Firewire (IEEE 1394) | a new very fast data bus that is used for newer peripherals and cameras. |
| AGP | accelerated graphics port, ) A bus specification by Intel which gives low-cost 3D graphics cards faster access to main memory on personal computers than the usual PCI bus |
| DMA | Direct memory access. The ability of certain intelligent highspeed I/O devices to perform data transfers themselves, with the help of DMA controller. |
| Adapter | A hardware device, such as a printed circuit board, that enables a personal computer to use additional peripheral devices or hardware. |
| Interrupt | A signal to a computer that stops the execution of a running program so that another action can be performed. |
| Jumper | A short length of wire used temporarily to complete a circuit or to bypass a break in a circuit. |
| Input/Output | This refers to any operation in a computer where data is transfered in or out of the computer. |
