VLAN

Overview

In old IT, to create a network, you plugged in several computers to a Switch or hub. This is called a Local Area Network. If I didn't want computer A to talk to Computer B, but I wanted it to be able to talk to the Internet, I'd have to have 2 sets of switches with different things attached. A Virtual Local Area Network (VLAN) uses software to divide a single switch into multiple "networks" instead of having to buy "side by side" networks of switches.
