Term Definition
Ethernet Local Area Network technology, originally developed by Xerox Corporation,
can link up to 1,024 nodes in a bus network.
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.
