Routers

Routers are small physical devices that join multiple networks together. There are many of them on the internet.

Home networks typically use a wireless or wired router.

When you key in a URL the router will decide where to go to find the website and then send it back to the correct PC.

Each router has an IP Address and this helps to send information to the right place.

An IP router such as a DSL or cable modem broadband router joins the home's local area network (LAN) to the wide-area network (WAN) of the Internet.
