A cable modem is a hardware device that enables high-speed internet access by transmitting and receiving data over a coaxial cable television (CATV) network. It acts as a bridge between a user’s local network and their internet service provider (ISP), converting digital signals into RF signals and vice versa. Cable modems are commonly used in homes and businesses, supporting broadband internet services such as DOCSIS (Data Over Cable Service Interface Specification) for fast and reliable connectivity.
