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.
