10/100BaseT. 10-Mbps baseband Ethernet specification that uses two pairs of
twisted-pair cabling: one pair for transmitting data and the other for receiving
data. 10/100BaseT has a distance limit of approximately 100 meters per
segment.
100BaseT. 100-Mbps baseband Fast Ethernet specification that uses UTP
wiring. Like 10/100BaseT, 100BaseT sends link pulses over the network
segment when no traffic is present. These link pulses contain more
information than those used in 10/100BaseT.
ADSL. Asymmetric Digital Subscriber Line.
ARP. Address Resolution Protocol. Enables routers to obtain the Ethernet
address for a known IP address. See also Inverse ARP.
ATM. Asynchronous Transfer Mode.
BOOTP. Bootstrap Protocol. Used during network booting by a network node
to determine the IP address of its Ethernet interfaces.
DLCI. Data-Link Connection Identifier. Value that specifies a PVC or SVC
in a Frame Relay network. In the basic Frame Relay specification, DLCIs are
locally significant (connected devices might use different values to specify the
same connection). In the LMI extended specification, DLCIs are globally
significant (DLCIs specify individual end devices).
E1. Network connection with a capacity of 2.048, divided into 32 separate
channels (or DS0s).
EEPROM. Electrically Erasable Programmable read only Memory.
Nonvolatile memory chips that can be erased using electrical signals and
reprogrammed.
Ethernet. Physical connection commonly used for LANs. Runs over a variety
of cable types and provides theoretical bandwidth of 10 or 100 Mbps.
Invented by Xerox Corporation and developed jointly with Intel and Digital
Equipment Corporation.
Fast Ethernet. Any of a number of 100 Mbps Ethernet specifications.
