What is a coaxial cable used for?

A coaxial cable is primarily used for transmitting data, video, and audio signals. It consists of a central conductor, insulating layer, metallic shield, and an outer sheath, which helps to minimize interference from external sources. This design makes coaxial cables suitable for a variety of applications, including cable television connections, internet access through cable modems, and even in some home theater systems.

In the context of internet access, most cable Internet Service Providers (ISPs) utilize coaxial cables to deliver broadband services. When connected to a cable modem, coaxial cables allow for high-speed data transmission, enabling users to access the internet quickly and reliably, thus serving a critical role in home and commercial network setups.

Do I need a coaxial cable for my internet connection?

Whether you need a coaxial cable for your internet connection depends on the type of internet service you have. If you have cable internet service, then yes, you will need a coaxial cable to connect your modem to the wall outlet provided by your ISP.
