10BaseT
An implementation of the Ethernet IEEE (802.3) based on shielded or
unshielded twisted pair cable. 10BaseT uses the star wiring topology
based on a centrally located hub.
All MICROS PC Workstations include an Ethernet 10BaseT port.
Active Matrix LCD
A type of LCD that uses a transistor at each pixel to produce a high
quality image without the temporary visual loss of the screen pointer
associated with passive matrix displays. Active displays are brighter,
crisper, can be viewed from greater angles than passive matrix
displays, and they do not tend to produce ghost images, or trails when
motion is displayed.
See Passive Matrix
ASCII
Abbreviation for American National Standard Code for Computer
Information Exchange. The standard ASCII code consists of a pre-
defined set of alphanumeric, control, and graphics characters. The 7-bit
coded characters allow information to be exchanged between
computers and peripheral devices.
Adapter Card
A printed circuit card that can be installed in the expansion connectors
of an IBM Compatible PC to extend or enhance its operation. An
internal modem board is an example of an adapter card. See Also: ISA
Riser Card.
Adapter ROM
The read-only memory on some expansion boards which contains code
to control the device. The contents of Adapter ROMs are normally
appended to the system BIOS ROM at start-up.
