4.  After processing the POS needs to send the data back to the PC. To do this it uses the

MWS (Manager Workstation) address. This is the address that all data from the POS will

be sent. In this case it is 62.136.7.167. If the POS sent the data to this address the data

would not arrive. The reason for this is because looking at the diagram, all IP addresses
around the POS begin with 192.168.0.n The POS is 192.168.0.1 and the router is

192.168.0.100.

5.  To enable the POS to speak with the PC VIA the router we have to tell the POS to send

the data VIA  another address. This is called the gateway address, and in this case is the

internal address of the router 192.168.0.100. So the POS sends the data to

192.168.0.100 for sending to 62.136.7.167

6.  The router receives the data and sends it to the PC who then receives the data
