How many times have we faced an acronym for information technology and don't know what that means ? The Information Technology world is full of acronyms to identify this or that technology. After talking about the FTP, HTTP acronyms and the WWW acronym, now let's see what the URL acronym means. Everyone will know that the URL is the string that identifies a Web page and allowing you to access it. Then type in your browser or click on a character a string consisting of HTTP / / WWW and followed by the domain name, domain extension and so on ...

In practice, thanks to an URL we identify uniquely by a sequence of characters, a resource on the Internet can be a web page, one image, document, etc. ... Each URL corresponds to a numeric address that connects the host names to own IP addresses. When entering an address, it is transformed into its numeric Internet Protocol (IP) through the Domain Name System (DNS), which is a database that collects them all.

Following is the address of the server that identifies the domain name or IP address, as www.ciccio, after the extension site that can identify the country or nation (.it is going to Italy. uk for United Kingdom . eu for Europe, etc. ...). The extension ORG for example, identifies an organization site.

Following the extension, separated by slashes, we may find folders to access site pages or documents, pictures, videos, etc. ...
