A URL is another word for a web address.
A URL can be composed of words, such as "w3schools.com", or an Internet Protocol (IP) address: 18.104.22.168. Most people enter the name of the website when surfing, because names are easier to remember than numbers.
URL - Uniform Resource LocatorWhen you click on a link in an HTML page, an underlying <a> tag points to an address on the world wide web.
A Uniform Resource Locator (URL) is used to address a document (or other data) on the world wide web.
A web address, like this: http://www.nabeeljamil.blogspot.com/ follows these syntax rules:
- scheme - defines the type of Internet service. The most common type is http
- host - defines the domain host (the default host for http is www)
- domain - defines the Internet domain name, like w3schools.com
- :port - defines the port number at the host (the default port number for http is 80)
- path - defines a path at the server (If omitted, the document must be stored at the root directory of the web site)
- filename - defines the name of a document/resource
