Uniform Resource Locator
What is Uniform Resource Locator?
A uniform resource locator (URL) is a text-based address that identifies the location of a resource on the web, and can contain the protocol, the domain name and the web page or file name; it is not itself an IP address.
This definition is part of the The Internet and its Uses chapter in Cambridge O Level Computer Science.
Uniform Resource Locator in context
A uniform resource locator (URL) is a text-based address that identifies where a particular resource on the web can be found. It can contain the protocol to be used, the domain name of the site, and the path and web page or file name of the resource being requested. A URL is written for people to read and type; it is not the numerical address the network uses. The domain name inside it must first be resolved to an IP address before any request can be sent.
