A cable modem is a device that connects your home network to the internet through a cable television line. It converts the data from the internet into a format that your devices, like computers and smartphones, can understand. This allows you to access the web, stream videos, and play online games.
Cable modems typically work with Internet Service Providers (ISPs) that offer cable internet services. They can be standalone devices or combined with a router to provide both internet access and Wi-Fi connectivity. Many homes use cable modems because they offer high-speed internet options.
