E

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.
