Networking is a connection between two or more computers, even when you connect two computers via a USB cable. Networks use standardized hardware, like Twisted pair cabling and Ethernet hubs, ATM switches and optical fibre cabling. Internetworking is a connection between two or more networks, like an Ethernet network connected to another Ethernet network by glass fibre cable and ATM switches.
