When fail function is invoked when creating an ajax request

Given : When making an Ajax request with jQuery, a failure callback gets invoked in case there is any error while making the request.

Can you explain what does it mean "while making the request" ? Can you give me examples.

in other words, when does the fail function is invoked ?
