What's is coaxial cable?

Coaxial cable is a type of electrical cable that is commonly used for transmitting radio frequency signals. It consists of a central conductor wire surrounded by an insulating layer, a metallic shield, and an outer insulating layer. The design of coaxial cable allows for high-frequency signals to be transmitted with minimal interference and signal loss. Coaxial cable is commonly used in television and internet connections, as well as in networking and telecommunications applications.
