Description of Terms
Bridge
A functional unit interconnecting two or more local area networks (LANs)
that uses the same link protocol. The bridge not only transmits but also
filters packets. The bridge usually operates on a Data Link Layer when it
transmits packets.
DMT (Discrete Multi-Tone)
A modulation technique of segmenting and transmitting a large amount of
data by way of Multi-carrier, in which a carrier frequency band is
multiplexed, thereby realizing optimal performance on a Loop.
Ethernet
A representative method of interconnecting LANs was using a
transmission cable of 10BASE standard. Three companies, i.e., Xerox, Intel
and DEC develop this method, in cooperation. Its transmission rate is
about 10 Mbps, and employs a CSMA/CD access method in which a node
monitors signals over a transmission line and sends data after confirming
that the other nodes do not send signals.
Hub
A communications interface used for interconnecting a series of devices on
a network. This retransmits a signal, which is received from a device, or
segments a received signal and transmits the segmented signal.
FTP (File Transfer Protocol)
A protocol for transferring files from one host to another or from a host to a
personal computer over a network.
