What is the function of a BNC connector?

A BNC (Bayonet Neill-Concelman) connector is a type of coaxial cable connector commonly used for RF (radio frequency) applications. Its primary function is to provide a quick and secure connection for transmitting video signals, data, and audio, especially in professional video equipment and telecommunications. The bayonet coupling mechanism allows for easy connection and disconnection while ensuring a reliable electrical connection. BNC connectors are widely used in broadcast, surveillance, and networking applications.
