Url?

When going to different websites we very rarely know what we actually are typing in to the computer. What does http mean? What about www? Well first of all you need to know that a url, or uniform resource locator, is a string of characters that indentifies an Internet resources type and location. It is much easier to remember www.yahoo.com then it is to remember the ip address for that site. Each site is given an IP address, or Internet Protocol address, a numerical id and address that is assigned to the computer network.
