message format consists of a header (containing identifying and
control information), followed by the actual message content,
followed by a trailer (indicating that the message is completed).
metacode
Same as “native mode.” The method of speaking to and controlling
the image generator. These controls are used by the character
dispatcher to generate scan line information. This information is sent
in the form of character specifications to the image generator, which
uses it to compose the bit stream that modulates the laser.
MHz
megahertz. 1. Unit of cycling speed (one million cycles per second)
for an electromagnetic wave (in particular, a radio wave). 2. Sending
and receiving stations of a radio wave transmission must be tuned in
to the same unit of megahertz.
mode
Manner in which an activity or process is carried out.
modem
Device that converts digital information into an analog signal suitable
for sending over analog telecommunication lines. Also converts an
analog signal from telecommunication lines into digital information.
module
Cohesive unit within a program. It is consistent in its level and
identifiable in terms of loading or with other units.
mouse
Electronic device used with the PC UI to select options and enter
data.
mouse pad
Base that provides friction and direction information to the electronic
mouse.
mouse tray
Optional extension module attached to the system controller to
accommodate the mouse pad and provide ample working space.
network
1. System of geographically separate computers, linked to one
another over transmission lines. 2. Communication lines connecting
a computer to its remote terminals.
nonimpact printer
Printer that forms characters without any strikes of a key or element
against the paper.
object file
Source file converted into machine language (binary code).
offline
Devices not under the active control of a central processing unit. For
example, a computer makes output to a magnetic tape. The tape is
then used by an offline printing system to produce printed data.
Offline operations are much slower than online operations. See also
online.
offset
To place pages currently being printed in slightly different positions
from previous pages.
