BNC
1. Short for Bayonet Neill Concelman connector, a BNC connector is
a connector used with coaxial Ethernet cable. The connector is bayonet-style, meaning that it is put in then turned and locked in
position. This connector is commonly used on a Token Ring network. BNC is also short for Bayonet Nut Connector or British Naval/Navy Connector although more appropriately known as the Bayonet Neill Concelman.
In the picture to the right, is an example of a BNC connector on the end of a
coaxial cable.
2. Short for bouncer, BNC is software that can be used to help protect and hide a user by relaying their IRC or FTP traffic over a network to their computer. For example, a user may connect to a computer using psyBNC and then relay traffic from that computer to their computer and connect to a IRC or FTP network to hide their true IP address. When this is done, the IP address would be for the computer that is running the BNC software.
