BNC
A BNC (Bayonet Neil-Concelman, or sometimes British Naval Connector)
connector is used to connect a computer to a coaxial
cable in a 10Base-T Ethernet
network. 10Base-2 is a 10 MHz baseband network
on a cable extending up to 185 meters - the 2 is a rounding up to 200 meters
- without a repeater cable. 10Base-2 Ethernets
are also known as "Thinnet", "thin Ethernet", or "cheapernets". The wiring
in this type of Ethernet is thin, 50 ohm, baseband
coaxial cable. The BNC connector in particular
is generally easier to install and less expensive than other coaxial connectors.
A BNC male connector has a pin that connects to the primary conducting
wire and then is locked in place with an outer ring that turns into locked
position.
