10Base2
Another Ethernet specification, 10Base2, describes a coaxial cable network that has a 10 Mbps baseband transmission rate over a maximum segment length of 185 meters.
This specification is also known as thin Ethernet, or thinnet, because of the type of cabling used.
Computers are daisy-chained together by segments of coaxial cable. There is a maximum of 30 hosts per segment.
Each end of a thinnet network must be terminated. This is because, unlike the 10BaseT specification, the wire does not terminate in the workstation and a hub.
The physical topology of a thinnet network is a bus.
