<ul><li>URL stands for Uniform Resource Locator , more commonly known as a web address. The address of every resource or file on the internet has a Uniform Resource Locator, including an address of a web page, audio stream or other internet resources. URL’s consists of protocol of the resources, domain name for the resource and address of the file. The first part of the address is called a protocol identifier and it indicates what protocol to use, and the second part is called a resource name and it specifies the IP address or the domain name where the resource is located. The protocol identifier and the resource name are separated by a colon and two forward slashes. </li></ul>
What function does it perform in the context of the internet?
<ul><li>URL’s connect the browser to the webpage. The address that we type in locates the specific web page that can be viewed anywhere in the world at any time, just by a simple click on the mouse. </li></ul>
<ul><li>There are three main types of URL addresses. Static URL, Dynamic URL, Directory URL. URL’s that connects the destination without generating programming Scripts is called Static URLs. In Static URLs, contents of the web page stay the same unless the changes are hard-coded into the HTML. The URL that uses the programming script to connect to the destination is called dynamic URL. A dynamic URL is a page address that results from the search of a database-driven web site or the URL of a web site that runs a script, dynamic URLs are generated from specific queries to a site's database. Directory URL has no file name that points the default file of the directory. </li></ul>
<ul><li>When you use the Web or send an e-mail message, you use a domain name to do it. For example, the Uniform Resource Locator (URL) " http://www.howstuffworks.com " contains the domain name howstuffworks.com. So does this e-mail address: firstname.lastname@example.org. Every time you use a domain name, you use the Internet's DNS servers to translate the human-readable domain name into the machine-readable IP address. </li></ul><ul><li>URL’s are used to locate a certain webpage, or site. </li></ul>
