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 is roughly
half that required for a non-interlaced system of the same resolution.
This results in less costly hardware. It also may make it possible to
display a resolution that would otherwise be impossible on given
hardware. The disadvantage of an interlaced system is flicker,
especially when displaying objects that are only a few scanlines
high.

IQ Signals

Similar to the color difference signals (R-Y), (B-Y) but using
different vector axis for encoding or decoding. Used by some USA
TV and IC manufacturers for color decoding.

ISA (bus)

Industry Standard Architecture (bus). The de facto standard system
bus for IBM-compatible computers until the introduction of VESA
and PCI. Used in the reference platform specification. (IBM)

ISASIO

ISA Super Input/Output device

ISDN

Integrated Services Digital Network. A standard for digitally
transmitting video, audio, and electronic data over public phone
networks.

LAN

Local Area Network

LED

LFM

Linear Feet per Minute

little-endian

A byte-ordering method in memory where the address n of a word
corresponds to the least significant byte. In an addressed memory
word, the bytes are ordered (left to right) 3, 2, 1, 0, with 3 being the
most significant byte.
