A URL (Uniform Resource Locator) is a web address that directs a browser to a website or resources on the internet. It is a unique identifier used to locate a resource on the internet. URLs consist of multiple parts, including a protocol and domain name, that tell a web browser how and where to retrieve a resource. The main components of a URL are:

  • Protocol identifier: This indicates the name of the protocol to be used to fetch the resource. Examples of protocols include HTTP (Hypertext Transfer Protocol) and HTTPS (HTTP Secure) for web resources, mail to for email addresses, FTP for files on a File Transfer Protocol (FTP) server, and telnet for a session to access remote computers.

  • Domain name: This identifies the IP address or domain name where the resource is located. Optionally, after the domain, a URL can also specify a path, which represents the building where the resource should be delivered.

  • Parameters: These represent extra information such as the number of the apartment in the building.

  • Anchor: This represents the actual person to whom the resource is addressed.

A URL can be thought of as the address of a given unique resource on the web. It is used by browsers to retrieve any published resource on the web. URLs can be quite long, but only four segments are typically referenced by users, all of which are on display in the URL. URLs are often colloquially referred to as web addresses or simply addresses, since web pages are the most common resources that users employ URLs to find.
