Dictionary of Computer and Internet Terms: 10base-2
10base-2
thinwire Ethernet; a type of Ethernet connection using thin coaxial cable with BNC T-connectors, a bus topology, and a maximum data rate of 10 megabits per second. Cable segments can range from 2 feet (0.6 m) to 607 feet (185 m) in length.
Usage note: In this and similar terms, 10 stands for the data rate in megabits per second; base means baseband (not modulated on a higher-frequency carrier); and 2 is the approximate maximum cable length in hundreds of meters. The hyphen is often left out.
