| bus | parallel collection of conductors that carry data or control signal from one unit to another |
| data bus | biderectional pathway linking the cpu to memory and i/o devices |
| address bus | pathway that carries data generated by cpu to various memory and i/o elements of the computer |
| pc bus | bus architectures used in first IBM Pc's, originally an 8-bit bus explained to 16 bit |
| isa | industry standard architecture 8- and 16- bit original connectors used in PC's they run at abus speed of 8 mhz |
| eisa | extended industry standard architecture 16- bit ia was extended to 32 bits they called eisa |
| pci | peripheral system interconnect. high performance 32/64 bit |
| plug and play | standard was supposed to make adding peripherals to your system as early as plugging them in and using them |
| bandwidth | measure in some amount of bits per second, amount of datacan be sentover in particular cable, interface or bus |
| bus master | any class of microprocessor unit with the ability to take control of the system buses of a computer |
| bus speed measurement, usually in mhz, of how many times data can be transferred over the bus per second | computer memory above the dos 1mb limit of reventional memory accessed by memory paging |
| legacy | describes older computer systems, hardware, software |
| fire wire (IEEE 1394) | high speed serial bus, allows for up to connection up to 63 devices primarily used for digital video |
| expansion slot | computer memory above the dos 1mb limit of reventional memory |
| adapter | device that allows one system to connect to and work with another |
| interrupt | signal that gets the cpu and is usually generated when i/o is required |
| i/o | on pc', three digit hexadecimal number (2AB, 2AO, and so on) used to indentify and signal a peripheral device like a serial port, parallel port, or sound card |
| jumper | small plug place over pins(or emoved pins) to configure hardware settings |
| dma | stand fordirect memory access. specialized cirtuitry or a dedicated microprocessor that tranfers data from adapters to memory without using the cpu |
| agp | advanced ecelerated graphic port |
