In simple terms a router routes data between 2 different networks. A network being 2 different IP subnets. Typically a Public IP (an Internet IP address) and a private IP (your local network)
Now you are probably asking how come I have 2 networks. You don't, but you do have 1 network, the other network is the Internet.
So the router is used as a device to allow your computer on your home network to talk to the Internet.
Your home network is that cable that goes from your computer to the router, or if you have wireless it is the wireless link between your computer and the router.
Modems are for the most part just media converters. It converts your xDSL connection to Ethernet. Now because what is presented at the Ethernet connection is effectively raw internet it needs something that is capable of getting data into and out of that connection, that is where your router comes in.
I hope this has been of some use to you.
