BNC connectors (Bayonet-Neill-Concelman or British Naval Connector) are connectors for coaxial cables. The BNC family is made up of the following elements:
- BNC cable connector: is either soldered or crimped to the end of the cable.
- BNC T-connector: links a computer's network card to the network cable
- BNC barrel connector: joins two lengths of coaxial cable, to make a longer cable.
- BNC terminators: placed at both ends of a bus cable to absorb stray signals. They are grounded. A bus network cannot function without them. It would be out of service.
