GLOSSARY-13
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.
MICR
Magnetic Ink Character Recognition. MICR allows a computer to
read characters printed in special metallic ink by scanning the
shapes of their magnetic fields. MICR fields are often imprinted
on bank checks before processing.
mixed environment
Multiple Xerox printers or printing systems (for example, 9790
and 4090 printers) in the same location.
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.
monitor
Program used to supervise, control, or verify the operations of a
system.
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.
node
Station, terminal, or computer that performs some control
operation and influences the operation of the network as a
whole.
nonimpact printer
Printer that forms characters without any strikes of a key or
element against the paper.
