What is the purpose of a coaxial cable?

The purpose of a coaxial cable is primarily to transmit high-speed internet signals, as well as other types of data such as television and radio signals. Coaxial cables are designed with a central conductor surrounded by an insulating layer and an outer conductive shield, which allows for the efficient transmission of signals while minimizing interference. This construction makes them ideal for applications requiring high bandwidth and minimal signal loss, such as broadband internet and cable television.

Though coaxial cables may also play a role in other contexts relating to signal distribution, the primary function that distinguishes them is their ability to deliver high-speed internet and multimedia content effectively. The structure is specifically optimized to support the frequencies used in these communication systems, which is crucial for maintaining high data rates and reliability in modern communications.
