| DIMM |
| |

Inline Memory
Module) The memory module used
in most computer systems. Memory modules in older systems needed
to be installed in pairs (they were known as SIMMS). With the
advent of DIMMS, a single memory module can be installed unpaired. |

over traditional SDRAM modules.

| DVD(Digital
Video Disk) |
| |
|
Similar to a CD-Rom drive,
it reads special DVD disks that hold up to 4.7GB of data as
opposed to a typical CD's 650MB. Due to its large storage
capacity the defacto purpose for a DVD drive is to play back
movies, but as storage needs increase, DVD drives will soon
become the de-facto method of file storage and retrieval.
