Drop-Down Menu
In graphics-supported programs, a menu line is positioned on the top edge of the
screen. The menu titles contained in this line can be set either as drop-down or
pull-down menus. Drop-down menus “roll” down as soon as the mouse pointer
passes over a menu title. Pull-down menus only “roll” down when the menu title is
clicked on. Different functions can then be called from these menus by moving the
mouse and clicking on an item in a menu.
DVD
Digital Video Disc. A digital video disc can store greater amounts of data than a
traditional CD. A standard single-layer, single-sided digital video disc can store 4.7
GB of data; a two-layer standard increases the single-sided disc capacity to 8.5
GB. Digital video discs can be double-sided with a maximum storage of 17 GB per
disc. A digital video disc player is needed to read digital video discs; this player is
equipped to read older optical storage technologies.
E
EIDE
Enhanced Integrated Drive Electronics. An extension of the IDE standard, EIDE is
a hardware interface standard for disk drive designs that house control circuits in
the drives themselves. It allows for standardized interfaces to the system bus while
providing for advanced features, such as burst data transfer and direct data
access. EIDE accommodates drives as large as 8.4 gigabytes (IDE supports up to
528 megabytes).
