module
A printed circuit board that contains electrical components and electrically
conductive pathways between components. A module stores data or mem-
ory or controls the functions of a device.
multiport repeater
A repeater used to connect two or more cable segments. The repeater lets
you extend Ethernet networks beyond the limits imposed by a single seg-
ment. Repeaters perform the basic actions of restoring signal amplitude,
waveform, and timing amplitude to normal data and collision signals.
multisegment LAN
A LAN composed of more than one cable segment.
network
A group of individual computer systems that are connected by communica-
tions lines to share information and resources.
network coordinator
The network coordinator manages the network, assigns unique node names
and addresses for each system on the network, and provides administrative
assistance to network users.
node
An individual information-processing unit, such as a computer, worksta-
tion, or peripheral device, that is connected to a network. A node is an
end point to any branch of a network or a junction common to two or more
branches.
operating system
A collection of system programs that controls the operation of the system
and allows the user access to data files, input/output devices, and appli-
cations programs. The operating system software performs such tasks as
assigning memory to programs and data, processing requests, and schedul-
ing jobs. VMS and ULTRIX are the two operating systems available for the
MicroVAX 3100 and VAXserver 3100 systems.
output device
A device that accepts data from the system. A printer is an example of an
output device.
