URL stands for Uniform Resource Locator, which is the address of a resource, such as a specific webpage or a file, on the internet. It is a specific character string that is used to access data from the World Wide Web. The URL is a type of URI (Uniform Resource Identifier) . It was created in 1994 by Tim Berners-Lee and the Internet Engineering working group.

A URL contains the following information:

• Protocol name
• A colon followed by double forward-slash (://)
• Hostname (domain name) or IP address
• A colon followed by port number (optional – unless specified otherwise, “:80” is the default when using HTTP, and “:443” is the default when using HTTPS)
• Path of the file

The most important parts of a URL are the protocol, hostname, and path. The protocol is the standard set of rules that are used to allow electronic devices to communicate with each other. The hostname describes the name of the server on the network. The path describes the pathname to the file on the server.

In summary, the full form of URL is Uniform Resource Locator, which is a specific character string that is used to access data from the World Wide Web. It contains information such as the protocol, hostname, and path of the file.
