disk cache
Using the hard drive as a memory cache for faster data retrieval. Disk cache is used as temporary higher-speed storage and transfer of data. Cache is used because it improves computer performance making it faster. Cache memory can also be dedicated fast RAM memory.
dual inline memory module - DIMM.
A pre-assembled RAM module that contains many smaller memory chips. A dual inline memory module has a 168-pin connector allowing for 64-bit data transfer, twice the data transfer rate of SIMMs (single inline memory module).
FAT - file allocation table.
1. A table used by an operating system to keep track of the files stored on the hard drive disk. Often files are broken into segments on a hard drive disk with each segment being record by FAT and associated with that file. The FAT is used when the file is open or run so the various segments can be sequenced together.
2. An application that is compiled to run on 2 platforms. For instance, on Macintosh® computers, a FAT application could run on a PowerPC or a 680x0 platform.

fixed width
As applying to fonts, fixed width fonts are fonts whose characters take up the same amount of space independent of the specific character. For example, both an "i" and an "o" will take up the same amount of space even though the characters themselves are different widths. Variable width fonts (also called proportional fonts) are those fonts in which the characters take up different widths.
flash memory
Similar to RAM except it does not lose its information when the power is shut off and is slower.
format
1. To format a disk to be compatible with a specific platform. Also called initialization of a disk.
2. The way text is arranged in a document with such formatting as columns, bold, font size, etc.
