Coaxial cables can be used to transmit both analog and digital signals and are suitable for a wide variety of applications, most notably television broadcasting, long-distance telephone transmission, short-distance connections between computer systems, and local area networks (LANs). Coaxial cable has developed rapidly as a means of transmitting television signals to households, leading to cable television.
