What is URL?
In the area of computing, URL stands for Uniform Resource Locator. All web pages in the World Wide Web can be accessed using their directory name, the URL. The URL is a file or page’s global address, a unique ‘folder’ that when typed in a browser will bring you to a specific location.
Whenever people surf the internet, they make use of browsers. While there are many browsers available, all developed with different features and functions, they are all the same in the way that they work with URLs to deliver the web pages that the user wants to access.
A typical URL will look like this: http://www.example.com. The first part HTTP stands for Hypertext Transfer Protocol (also called a ‘scheme name’ or ‘protocol identifier’), which is a protocol for the transfer of information between servers and browsers. HTTP is followed by a colon, a double slash (which serves to separate the directory or folder file from the resource name), then by www, which stands for World Wide Web. It is then succeeded by the specified website name (in this instance, ‘example’), followed by the top level domain .com, which stands for ‘commercial’, pertaining to its original purpose to be used for general commercial use. Other top level domains include .org, .edu, and .net.
The URL was developed by Tim Berners Lee in 1994 along with others from the Internet Engineering Task Force group. A URL can be short, as in the case of the main page of a website, and could go longer as more sub-folders are used, for instance http://www.example.com/subfolder1/subfolder2.
