Modem - Box from your ISP that connects to the internet. It actually connects to the phone line or the coaxial cable or whatever physical line you have. It normally has at least an ethernet connection, sometimes a USB as well. Router - Box that connects to the modem and allows multiple devices to use that internet connection at the same time. It also lets the devices talk to each other (so you can transfer files in your house or whatever).
In order for devices on the network to connect to the Internet, the router must be connected to a modem. Therefore, most routers have a specific Ethernet port that is designed to connect to the Ethernet port of a cable or DSL modem. A modem is a device that provides access to the Internet (see below). The modem connects to your ISP, which typically provides either cable or DSL Internet service.
