A URL is what we call a Uniform Resource Locator.
It basically gives us a memorable *address* that we can use to reference certain IP addresses (such as servers and other nodes) on a TCP/IP network such as the internet.
For example answers.yahoo.com is a URL that points to the Yahoo servers and tells the server that you want to see the webpage for Yahoo Answers.
It saves us having to remember an Ip address such as 192.168.2.1 to access such resources.
[edit fixed up my mixup lol sorry forgot that it is Uniform not Universal *hehe*]
