What is the common name for a coaxial cable?

The common name for a coaxial cable is often referred to as a television cable. This is due to its widespread use in connecting televisions to cable and satellite services. Coaxial cables are specifically designed to carry high-frequency signals with minimal interference, making them ideal for transmitting television signals, as well as broadband internet data.

Although coaxial cables can carry video signals, as implied by one of the other options, the term "television cable" is more commonly used in everyday language, especially among consumers who might not be familiar with technical terminology. This understanding aligns with the history of coaxial cable usage, particularly in residential settings where it has been primarily associated with cable television and signal distribution.

Other options such as fiber cable and sound cable relate to different types of cabling technologies that serve different purposes. Fiber cables utilize light for data transmission, typically offering high-speed internet connections, while sound cables are focused on audio applications and do not encompass the functionalities of coaxial cables. Therefore, the term "television cable" best captures the primary and most recognized use of coaxial cables.
