02.Packet-switching
you switch on your PC & connect to your favorite site that offers a number of application you can download from,so you begin downloading one applications at the time ,Each packet has to find its own route the destination ,
For instance :your computer .Each packet finds its way using the information it carries ,such as the source & destination IP Address .If network congestion occurs,the router responsible for routing packets between networks will automatically select different paths to ensure data is transferred as required.
Thank you for the simple and brief explanation,It's really useful.
