Internet without URL?

 

This question already has an answer here:

  • What is the difference between a URI, a URL and a URN? 33 answers

    • That's simple but yet confusing. In simple words, "every URL is a URI but not every URL is URL". When you specify a protocol or connection format with URI, it becomes URL eg

    example.com is a uri http://example.com is a url ame is for ftp://, mailto: etc

    So practically, you can't us just the uri to access the server because you need to specify what type of connection you want unless you enter the address directly in the browser which uses http:// by default

    Regarding the questions about searches, so that's true, when ever you make a request, the dns first finds the URI regardless of the connection type then that's your browser which will try to make a connection to the server using a required protocol. So its like this:

    Browser ---> Sends URI to DNS SERVER Browser <--- DNS server Sends back an IP Browser ---> adds a protocol, making the url from uri and try to connect to server
