| 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 by 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 is a PC bus standard that extends the 16-bit ISA bus (AT bus) to 32 bits and provides bus mastering. |
| PCI | peripheral system interconnect. A high performance 32/64-bit bus. |
| Plug and Play (PnP) | In Plug and Play (PnP), the configuration of adapters is performed by the operating system. |
| Bandwidth | A measure, in some amount of bits per second, of the amount of data that can be sent over a particular cable, interface, or bus |
| Bus Master | any class of micro-proccesor units with the ability to make control of the system buses. |
| 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, it's limited to ISA, EISA, PCI, and PCMCIA. |
| AGP | accelerated graphics port, ) A bus specification by Intel which gives low-cost 3D graphics cards faster access to main memory. |
| DMA | Direct memory access, the abilityof certain intellegent highspeed i/O devices to preform data transfer themselves, withthe help of DMA controlles. |
| Adapater | 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. |
| I/O Address | On PCs, a three-digit hexadecimal number (2AB, 2AO, and so on) used to identify and signal a peripheral device like a serial port, parallel port, or sound card. |
