10base2 - Computer Definition
The IEEE standard (1986) for relatively thin coaxial cable in support of Ethernet transmission. Also known as ThinNet (Thin EtherNet), 10Base2 translates to 10 Mbps (theoretical transmission rate), Baseband (one transmission at a time over a single, shared channel), and 200 meters maximum segment length (actually 185 meters, rounded up). The thinner cable is less costly to acquire and deploy than earlier 10Base5, although its performance is less in terms of transmission distance due to increased attenuation. See also 10Base2, attenuation, baseband, channel, coaxial cable, Ethernet, IEEE, and transmission rate.
An earlier 10 Mbps Ethernet standard that used a thin coaxial cable. Network nodes were attached to the cable via T-type BNC connectors in the adapter cards. Also called "thin Ethernet," "ThinWire," "ThinNet" and "Cheapernet," 10Base2 had a distance limit of 607 feet. See 10Base5, 10Base-T, Ethernet and CSMA/CD.
