Glossary
Extended Capabilities Port (ECP)
An option available in your computer's BIOS which affects the way a printer attached
to your parallel port communicates with your computer. If your printer supports this
standard, enabling the ECP option will allow faster printing.
extended memory (XMS)
Memory beyond 1 MB that can only be accessed by use of extended memory
manager software (such as HIMEM.SYS, included with MS-DOS and Windows).
Some application software, including Windows and Windows-based software,
requires extended memory in order to operate correctly. Extended memory can be
added to your computer, within specified limits, by installing SIMMs.
fast ethernet
Fast Ethernet is a new technology that can be integrated into current 10Base-T Local
Area Networks (LANs) and allow them to scale easily to 100 Mb/s. Fast Ethernet
provides higher bandwidth without a major change in infrastructure.
firmware
Information that is permanently stored in your computer's ROM and cannot be
changed. This might consist of application software and/or configuration information
about certain aspects of the computer. Your computer's BIOS (see Basic
Input/Output System) is an example of firmware.
graphical user interface
Abbreviated as GUI. The visual "desktop" image generated by software such as
Windows, that allows you to operate your computer by using a mouse or other
pointing device to manipulate icons that might represent application software, files
containing data, and/or operating system commands. An alternative to a command
line.
