Need A Help in URL and URI

Question

Hello Everyone, We all use many URLs on a daily basis. Sometimes we type them, sometimes we are just redirected to one URL by another. I have faced an interview someone asks me the difference between URI and URL. I have google it but till now I didn't get the exact answer. Anyone explain to me the syntax of both.

Hello Arjun, URI = Uninform Resource Identifier URL = Uniform Resource Locator The difference between the two is that a URI is basically a name, its a representation of an entity of some kind of resource somewhere Whereas a URL specifies where that resource can be http://found.so a URL is a URI but a URI is not a URL URI isn’t going you to show where a resource can be found but URL does. E.g http://public://my_life.jpg -----> URI http://sites/default/files/my_life.jpg 2 -----> URL URI is pointing to a location on the server that is publically accessible URL is also pointing to a location but it may more, like what protocol was using in order to access the file. Well, if you want to know if that ‘something’ is URI or URL, you should always mark it as a URI because all URLs are URIs.
