What is VPN?
Stands for "Virtual Private Network." (Not a competitor of UPN). This is a network term that most computer users don't need to know, but at least you can impress your friends by talking about it. A VPN refers to a network that is connected to the Internet, but uses encryption to scramble all the data sent through the Internet so the entire network is "virtually" private. For example, a large company that has offices in multiple locations may need to send data to the different locations via the Internet. To keep the information secure, the company might first set up a VPN with an encrypted connection. It's basically like having a secure Intranet over the Internet.
