Term	Definition
Ethernet	Local Area Network technology, originally developed by Xerox
	Corporation, can link up to 1,024 nodes in a bus network. Ethernet
	provides raw data transfer in a rate of 10 megabits/sec. with actual
	throughputs in 2 to 3 megabits/sec. using a baseband
	(single-channel) communication technique. Ethernet uses carrier
	sense multiple access collision detection (CSMA/CD) that prevents
	network failures when two devices attempt to access the network at
	the same time. LAN hardware manufacturers use Ethernet protocol;
	their products may not be compatible.
Gateway	A computer that attaches to a number of networks and routes packets
	between them. The packets can be different protocols at the higher
	levels.
IP	Internet Protocol – The TCP/IP standard protocol defines the IP
	datagram as the unit of information passed across a network.
IP Address	Internet Protocol Address – A 32-bit address assigned to hosts
	participating in a TCP/IP network. The IP address consists of
	network and host portions. It is assigned to an interconnection of a
	host to a physical network.
MAC	Medium Access Control - The network layer between the physical and
	the data link layers. Specifically, the physical (hardware) address
	exists in this layer.
MIB	Management Information Base – The database, i.e. set of variables
	maintained by a gateway running SNMP
NMS	Network Management Station
OID	Object Identifier – The variables defined in a MIB
Router	A computer that manages traffic between different network segments
	or different network topologies. It directs the destination IP address.
	The network media can be different, but the higher-level protocols
	must be the same.
SNMP	Simple Network Management Protocol – A standard protocol used to
	monitor IP hosts, networks, and gateways. SNMP defines a set of
	simple operations that can be performed on the OIDs of the MIBs
	managed by the monitored Agents. It employs the UDP/IP transport
	layer to move its object between the Agents and the NMS
TCP/IP	Transmission Control Protocol/ Internet Protocol – A protocol suite
	used by more than 15 million users with a UNIX association and
	widely used to link computers of different kinds.
