EMI
Electromagnetic interference. Interference by electromagnetic signals that can
cause reduced data integrity and increased error rates on transmission channels.
ESD
Electrostatic discharge. A transfer of electrostatic charge between bodies of
different electrostatic potentials, such as an operator and a piece of electrical
equipment. ESD occurs when electronic components are improperly handled
and can damage equipment and impair electrical circuitry. ESD is more likely to
occur in the presence of synthetic fibers and dry atmosphere.
F
Flash memory
The nonvolatile storage that can be electrically erased and reprogrammed so that
data can be stored, booted, and rewritten as necessary.
G
G.SHDSL
Symmetrical high-data-rate digital subscriber line technology that enables
high-speed transmission over the “last mile” between the service provider and
the customer site.
M
MDI
Media-dependent interface. A port on an Ethernet network device used to
connect the device to the Ethernet network, usually through a hub or switch.
MDI-X
Media-dependent interface, crossover. A port on an Ethernet hub, such as the
Cisco 1528 Micro Hub 10/100, that connects the Ethernet network devices
through the MDI port to create a network.
