BNC connector(Bayonet Nut Coupling) A commonly used plug and socket for audio, video and networking applications that provides a tight connection. Using a mount somewhat similar to the way a bayonet (knife) is mounted onto the end of a rifle, BNCs are used to connect a variety of different coaxial cable types. After the plug is inserted, it is turned, causing pins in the socket to be pinched into a locking groove on the plug.
TNC (Threaded Nut Coupling)
For a more secure connection, TNC is a threaded version of BNC that uses screw threads instead of a locking pin and slot.
A Lotta Names
There are numerous definitions of the BNC acronym, including Bayonet Neill-Concelman (after its inventors), Barrel Nut Connector, Bayonet Nipple Connector, Bayonet Navy Connector, Baby N Connector, British Naval Connector and British National Connector. See A/V ports, coaxial cable and plugs and sockets.
|BNCs differ from many connectors because of their snap-lock architecture, which keeps the plug firmly in its socket.|
transportation network companyAn organization such as Uber and Lyft that uses mobile apps to enable people to secure individual and carpooling rides from drivers who use their own vehicles. The GPS capability in the smartphone identifies the pick-up location and keeps the customer informed in real time when the car will arrive.
Billing is automatically handled via pre-registered credit cards, and although tipping is enabled in the app, nothing prevents the passenger from handing the driver cash. Initially treated as contractors, drivers became classified as employees in Britain. The transportation companies are increasingly challenged by jurisdictions to change driver status to employee.
Also called a "ridehailing" or "ridesharing" service, in 2013, the California Public Utilities Commission created the transportation network company category to deal with these services. See Uber and Lyft.
