Sure, I think I can help you understand how a VPN works.  Do you mind if we talk for a bit to understand how this works and why people use them?
assistant

We could talk about some of the common types of VPNs, and what people use them for. Can I describe them for you?

Can you tell me what a vpn does first?

Sure. A VPN, or Virtual Private Network, is a secure method of connecting to a network, or “the cloud” in particular. It encrypts your communications and links you to a “VPN server” that’s connected to the internet.  Let me give you an example of a simple scenario where a VPN could be useful. Let’s say that you wanted to access a website but you’re afraid that other people might be spying on your internet activity and looking for information that you’re interested in or could be sensitive. With a VPN, you could hide your internet activity so that people who might be trying to watch you wouldn’t be able to find out what sites you are browsing.

Sure, I can explain what a VPN does.  A VPN is a virtual private network, where a computer can access a network over the Internet, but it will appear to be directly connected to a private network.
