A very, very simplistic view of Packet Switching. <br /><br />Basically data is split into separate packet. Each Packet can then be send via a different root. <br /><br />Each packet contains extra data to say where it is going and the order it should arrive in as well as some verifying data <br /><br />For more information about Packet Switching see:- <br />Packet Switching.
