ANATOMY OF A URL
What is a URL anyway?
URL stands forUniform Resource Locator
That’s just another way to say it’s an address pointing to an Internet resource.
Think of it like you think of your address.
The post office can’t deliver a letter unless there is a unique address to deliver it. You need the number of the house, the name of the street, the city or town and the correct zip code.
Every site on the Internet has its own unique URL.
You can learn a lot about the site just by understanding its URL.
Example http://www.google.com/
http Stands for hyper text transfer protocolThat indicates the means by which the data is sent over the Internet. (Some other protocols are ftp and mailto, but http is most common.)
www Stands for world wide web
google.com Is the domain name. The first part (google) must be registered officially to insure that there are not two identical domain names. The second part (.com) gives clues to the type of site it is.
