Glossary Definition for: VPN

A VPN encrypts all the data coming to and from your computer, and sends it to a remote VPN server that then connects to the public internet on your behalf. This prevents anyone on your local network from being able to eavesdrop on you in any way – they can’t even tell what sites you visit.

If you are traveling internationally, you can use a VPN server so that you appear still to be connected from your home country. Sites that block international traffic (like Netflix streaming) will still work, and other sites will continue to default to your native language.

A VPN will, however, introduce a small delay in all your network connections.
