| Bank | An area on the system board that contains slots for memory modules. |
| Buffer | A temporary memory area where data is kept before being written to a drive or sent to aprinter, thus reducing the amount of writes needed when devices communicate at different speeds. |
| COAST | (Cache On A STick) Chips on a module available for pipelined burst synchronous SRAM. |
| SRAM | (Static RAM), RAM chips that retain information without the need for refreshing as long as the power is on. They are more expensive but less volatile than traditional DRAM. |
| DRAM | (Dynamic RAM), Common system memory with access speeds ranging from 70 - 50 nanoseconds, requiring refreshing every few milliseconds. |
| Conventional Memory | Memory addresses between 0 and 640K. Also called base memory. |
| EDO memory | A type of RAM that may be 10-20% faster than conventional RAM because it eliminates the delay before it issues the next memory address. |
| Extended Memory | Memory above the initial 1024KB, or 1MB, area. |
| Expanded Memory | (EMS) Memory outside the conventional 640K and the extended 1024K range that is accessed in 16K segments, or pages, by way of a window to upper memory. |
| Memory | physical microchips that can hold data and programming located on the system board or expansion cards. |
