So it can be stated that any server that has internet location is said to be web URL or a web address. Every website or web address has a unique URL. For ex:- if the website of Punjab School Education Board has web address and web-URL called as http://pseb.ac.in/. whereas the file-Path states the location of the file inside the local computers folder structure. This acts just the file address by which we can use it. By making use of file paths and URL we can link the external resources like images, videos, style sheets, and other web pages etc. It is necessary for one to know the source of the file when you want/wish to insert it file into the webpage. For ex:- It is a must for one to know the path of the file of the image for specifying it in the HTML document if incase we wish to insert an image in the webpage. The URL is been formed by four basic parts which are Protocol, Host name, Folder name, File – name. for ex:-
There are two types of URL which are Absolute and Relative URL

This URL includes all the basic/detailed information which is required to search the files on the internet or on the local computer.
