A virtual private network is a system that changes your ip address and encrypts your internet connection. This means that your privacy is protected because you have a different ip address (internet protocol address is used to identify computers on the Internet) than the one you got from your internet provider.
But remember, if you log in to a account identified by your personal data (Facebook, Bank, Government Service) while connected to a Vpn, you will be identified. But when not logged in to a specific service, not even your Internet Service Provider can see your online activity. And that is a good thing.
