Partition

A portion of a hard disk that functions as a separate unit. A single hard disk can be divided into several partitions, each of which functions as a separate drive and has its own volume name (such as D:, E:, F:, and so on). The purpose is to make the drive more efficient, as the computer can search smaller sections for a specific file rather than the entire drive. The verb to partition refers to the process of dividing the hard drive into partitions.

LCD

Liquid-crystal display. Created by sandwiching an electrically reactive substance between two electrodes, LCDs can be darkened or lightened by applying and removing current. Large numbers of LCDs grouped closely together can act as pixels in a flat-panel display.

Digital Controls

Digital controls are buttons or similar mechanisms that alter settings in discrete steps, in contrast with the infinitely variable analog controls such as dials. The advantage of digital controls on a monitor is that you can store settings in memory and recall them (often automatically) at a later time. This lets you change resolutions without constantly fiddling with controls to correct the image.
