Define the difference between a URL and an IP address?

A URL, as stated before, is a name, designed for people to remember (IE yahoo.com). A DNS server is used to convert that name to an IP address, which is some odd number IE 209.191.93.52 which routers and computers understand that is used to forward your destination request to a computer IE a server at yahoo.com to send you a message/page back. After all, who on earth who be able to remember websites as a series of numbers (that's why we, as "normal people", use URLs instead of IP addresses)?!

So, in short:

The URL/"Domain Name" is something for you to remember
The IP is for the computer to use to send the message
The DNS is used to translate from the URL to IP address
