Table C-1. Glossary

Ethernet	A LAN specification developed jointly by Xerox, Intel and Digital Equipment
	Corporation. Ethernet networks transmit packets at a rate of 10 Mbps.
Fast Ethernet	An Ethernet system that is designed to operate at 100 Mbps.
Gigabit Ethernet	An Ethernet system that is designed to operate at 1000 Mbps (1 Gbps).
Fault isolation	A technique for identifying and alerting administrators about connections
	(such as those associated with switch ports) that are experiencing
	congestion or failure, or exceeding an administrator-defined threshold.
Forwarding	The process of sending a packet toward its destination using a networking
	device.
Filtering	The process of screening a packet for certain characteristics, such as
	source address, destination address, or protocol. Filtering is used to
	determine whether traffic is to be forwarded, and can also prevent
	unauthorized access to a network or network devices.
Flow control	A congestion- control mechanism. Congestion is caused by devices
	sending traffic to already overloaded port on a switch. Flow control prevents
	packet loss and temporarily inhibits devices from generating more traffic
	until the period of congestion ends.
Full-duplex	A system that allows packets to be transmitted and received at the same
	time and, in effect, doubles the potential throughput of a link.
Half-duplex	A system that allows packets to transmitted and received, but not at the
	same time. Contrast with full duplex.
IEEE	Institute of Electrical and Electronics Engineers. This American organization
	was founded in 1963 and sets standards for computers and
	communications.
IETF	Internet Engineering Task Force. An organization responsible for providing
	engineering solutions for TCP/IP networks. In the network management
	area, this group is responsible for the development of the SNMP protocol.
IP	Internet Protocol. IP is a layer 3 network protocol that is the standard for
	sending data through a network. IP is part of the TCP/IP set of protocols
	that describe the routing of packets to addressed devices.
IP address	Internet Protocol address. A unique identifier for a device attached to a
	network using TCP/IP. The address is written as four octets separated with
	periods (full-stops), and is made up of a network section, an optional subnet
	section and a host section.
LAN	Local Area Network. A network of endstations (such as PCs, printers,
	servers) and network devices (hubs and switches) that cover a relatively
	small geographic area (usually not larger than a floor or building).
