What is the primary use of a BNC connector?

  1. Audio transfers

  2. Power connections

  3. Coaxial cable for networking

  4. Fiber optic connections

The correct answer is: Coaxial cable for networking

A BNC (Bayonet Neill-Concelman) connector is primarily used for coaxial cables, which are commonly used for networking purposes. Option A, audio transfers, is incorrect because BNC connectors are not designed for transmitting audio signals. Option B, power connections, is also incorrect because BNC connectors cannot transfer or supply power. Option D, fiber optic connections, is also incorrect because BNC connectors are not compatible with fiber optic cables.
