Disk Drive
The disk drive (floppy disk drive) is used to store programs and data on diskette
(write access) or to load from diskette to the computer (read access).
Diskette
The diskette (floppy disk) is an external data access memory on which all types of
files and programs can be stored. The storage medium is a round magnetic disk in
a plastic cover to protect it from getting scratched.

Double-Click
Pressing and releasing the left mouse button very quickly twice in succession
without moving the mouse. This action is normally to open an object or program.
Drives
Devices for operating rotary disk media (diskettes, hard disk, CDs).
Drivers
These are programs which are part of the operating system. They adapt user
program data to the specific formats required by I/O devices such as hard disk,
printers, and monitors.
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.
E
EPROM/EEPROM Submodules
These are plug-in submodules with EPROM/EEPROM chips. S5 user programs
can be stored on them. These programmed submodules are then plugged into
specially designed slots in the programmable logic controller.
