Explanation
:start this is word with a colon is what the computer recognises and when you issue the goto then the word eg like goto start when all process are done you are saying to the system, hey boy return back and start from beginning

 @echo off will make sure that the commands typed donot display when its displayed on your screen.
 echo %random% this echo is a command that displays, so you are telling the computer to display numbers randomly from 1 to around 29615 or so, that is when you include the %random%
