FDDI
Fiber Distributed Data Interface. A network based on the use of
optical-fiber cable to transmit data in non-return-to-zero, invert-
on-1s (NRZI) format at speeds up to 100 Mbps.
FIFO
First-In, First-Out. A memory that can temporarily hold data so
that the sending device can send data faster than the receiving
device can accept it. The sending and receiving devices typically
operate asynchronously.
firmware
The program or specific software instructions that have been more
or less permanently burned into an electronic component, such as
a ROM (read-only memory) or an EPROM (erasable
programmable read-only memory).
frame
One complete television picture frame consists of 525 horizontal
lines with the NTSC system. One frame consists of two Fields.
graphics controller
On EGA and VGA, a section of circuitry that can provide
hardware assist for graphics drawing algorithms by performing
logical functions on data written to display memory.
HAL
Hardware Abstraction Layer. The lower level hardware interface
module of the Windows NT operating system. It contains platform
specific functionality.
hardware
A computing system is normally spoken of as having two major
components: hardware and software. Hardware is the term used to
describe any of the physical embodiments of a computer system,
with emphasis on the electronic circuits (the computer) and
electromechanical devices (peripherals) that make up the system.
HCT
Hardware Conformance Test. A test used to ensure that both
hardware and software conform to the Windows NT interface.

Input/Output
IBC
PCI/ISA Bridge Controller
IDC
Insulation Displacement Connector
IDE
Intelligent Device Expansion

interlaced
A graphics system in which the even scanlines are refreshed in one
vertical cycle (field), and the odd scanlines are refreshed in
another vertical cycle. The advantage is that the video bandwidth
