A 'subnet' is a term used to describe a portion of an IP address space, where each device in that space can communicate with one another without using a router:

If you have more than one PC, you need a 'switch' or hub to physically connect all of those devices, so they can all speak to each other. (fwiw, I cringe at the term subnet). I have a switch to connect all of these 3 pc's. Steve wrote: In the diagram above, you need two NICs in the gateway. One goes to the ISP, and the other 192.168.1.2 goes to the switch. The rest of the computers also plug into the switch. If all of the devices have 192.168.1.x, they are all in the same subnet. If the 2 pc's will be connected to gateway directly and another one with the switch, then all 3 pc's won't be in one subnet.
