404 error is simply an error ( code 404 ) message or a page sent back to the client ( our computer ) in response to our request for a particular webpage on that server. This happens because of 3 reasons: 1) The URL ( Uniform Resource Locator) or simply the address of the webpage we typed is wrong. 2) May be the page we are redirected or typed has been removed for some reason. 3) Or the server had been wrongly coded with wrong address, which is not found anywhere in the web. ( Rare, programmers are fired for that :) ).
