Newer models designed for home usage typically have four Ethernet ports for wired devices, a fifth port for connection to a modem, and a wireless networking antenna.

Routers used in business may have specialized uses, such as handling data for specific business servers, transferring data between other routers and providing secure connections to the Internet.Learn more about Internet & Networking
