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

Question

People talk about URLs, URIs, and URNs as if they\'re different things, but they look the same to the naked eye.

Answer 1

Easy to explain:

Lets assume the following

URI is your Name

URL is your address with your name in-order to communicate with you.

• my name is Loyola

  Loyola is URI

• my address is TN, Chennai 600001.

TN, Chennai 600 001, Loyola is URL

Hope you understand,

Now lets see a precise example

http://www.google.com/fistpage.html

in the above you can communicate with a page called firstpage.html (URI) using following http://www.google.com/fistpage.html(URL).

Hence URI is subset of URL but not vice-versa.
