Understanding VPNs and Internet Networks

Your VPN is basically a secret, encrypted tunnel through the public internet.

Think about it: your phone connecting to your headphones is a tiny Personal Area Network.

Your home Wi-Fi? That's a Local Area Network, or LAN. These LANs connect

to form city-wide networks, which then plug into the massive Wide Area Network

we call the internet. It all started as a US military project called ARPANET. Now,

it's a global collection of networks all talking to each other using a standard language,

TCP/IP. Every time you click a link, you're sending data packets through

this giant web.
