A wired router connects directly to computers through wired connections. As a result, all of the devices on your home network have internet access.
The router then creates and communicates with your home Wi-Fi network using built-in antennas. This allows it to receive information from - and transmit information to - the internet. A wireless router connects directly to a modem by a cable. When it comes to routers, there are only two types you’ll need to consider: With today’s internet connections, including cable and satellite, modems play a similar but different role. When most internet service was delivered over telephone lines, modems enabled communication between the digital devices in your home and the analog signals used on telephone lines. It then connects to your router, delivering that internet connectivity to your home network. The modem’s job is to bring the internet service from your provider into your home. In fact, without the modem, all you’d have is your local network with no access to the internet. How modems differ from routersĪ router and your devices aren’t the only components on your home network. As you add more and more devices - think Internet of Things - you ask your router to do more. Making sure that information is delivered quickly and correctly is a big task - and getting bigger.
The information traveling on your home network could be an email, a movie, or a live feed from your baby cam, each of which takes up varying amounts of bandwidth. A router directs incoming and outgoing internet traffic on that network in the fastest and most efficient way. With your router, these devices form a network. A typical home has a range of internet-connected devices - personal computers, tablets, smartphones, printers, thermostats, smart TVs, and more.
