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.
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.
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.
UIS
Uninterruptable Internet System - This is what controls the auto
reset functionality of the Remote Power IP Switch. With this setting
enabled, the Switch will monitor the Target Sites and automatically
reset power to any outlets the user assigns when the connection is
lost.
