differences between modems and router
Modem vs. Router. Modems and routers are both involved in connecting your home PCs to the Internet. The modem encodes and decodes data so that it can pass between your home network and your Internet Service Provider (ISP). The router, on the other hand, directs the information collected by the modem to devices within that network.
Weâre here to help. A router and modem are two very different devices, though many ISPs offer a combined modem/router unit. A router is a device thatâs connected to two networksâlike your home network and the Internetâand forwards traffic between them.
But you canât connect directly to the Internet with just a router. Instead, your router must be plugged into a device that can transmit your digital traffic over whatever type of Internet connection you have. And that device is a modem. Your modem serves as a bridge between your local network and the Internet.
