GL-9

Media

Physical cabling or other method of interconnection
through which network signals are transmitted and
received.

MIB

Management Information Base. A database of data related
to a specific management or manageable network device,
which may be viewed or modified through SNMP
commands.

MIB Tree

The MIB Tree is the collection of all MIBs that can be
used to monitor or control a network device. MIB Trees
are made up of several branch groups which lead to leaf
objects
, or MIBs.

Micron (

µ

)

A micrometer, one millionth of a meter.

MIM

Media Interface Module. See also: Module.

Mission-
Critical

Vital to the operation of a network, company, or agency.

Modular
Chassis

A device which provides power, cooling, interconnection,
and monitoring functions to a series of flexible and
centralized modules for the purposes of creating a
network or networks.

Module

A discrete device which is placed in a modular chassis to
provide functionality which may include, but is not limited
to; bridging, routing, connectivity, and repeating. Modules
are easily installed and removed. Also, any device
designed to be placed in another device in order to operate.
See also: BRIM, EPIM.

Multichannel

A Cabletron Ethernet design which provides three separate
network channels (of Ethernet or Token Ring architecture)
through the backplane of a chassis, allowing for the
creation of multiple networks in a single chassis.

Multimode

A type of fiber optics in which light travels in multiple
modes, or wavelengths. Signals in Multimode fiber optics
are typically driven by LEDs.

Nanometer

One billionth of a meter.
