GLOSSARY 3

IEEE

Institute of Electrical and Electronics Engineers. Committees that

 

develop and propose computer standards, such as the 802 protocols,

 

which define the physical and data link protocols of communication

 

networks. Members represent an international cross section of users,

 

vendors, and engineering professionals.

incoming

The ability of a device to receive pause frames. See symmetric

flow control

flow control.

LAN

Local area network. An assembly of computing resources such as PCs,

 

printers, minicomputers, and mainframe computers linked by a

 

common transmission medium, such as UTP.

LED

Light-emitting diode. A diode that converts voltage to light and that is

 

commonly used in digital displays.

MAC

Media Access Control. The data link sublayer that is responsible for

 

transferring data to and from the physical layer.

Mbps

Megabits per second.

outgoing

The ability of a device to send pause frames. See Asymmetric

flow control

flow control.

partition

A repeater function that isolates a particular port from the network

 

because of an excessive number of collisions. Once the problem

 

causing the collisions is corrected, the port is reactivated.

pause frame

A set of bits that tells a transmitting device to stop the transmission of

 

data frames for a specified period or to resume the transmission of

 

data frames.

power workgroup

A small number of servers or a small number of sophisticated users

 

on high-end workstations. A power workgroup requires very high

 

performance to run applications that move and process massive

 

amounts of data in real time (for example, medical imaging, video

 

editing, film postproduction, CAD/CAM, or digital prepress).

repeater

A device that extends the length, topology, or interconnectivity of

 

the physical medium beyond that imposed by a single segment, up

 

to the maximum allowable end-to-end trunk transmission line length.

 

Repeaters perform the basic actions of restoring signal amplitude,

 

waveform, and timing applied to normal data and collision signals.
