VPN (Virtual Private Network) is a service that creates a secure, encrypted tunnel between your computer and a server in another location. This allows you to access websites from other countries through the server rather than your own. When you connect to the internet, your data is routed through this tunnel and all other users connected to that server. This means that it's complicated for anyone to track what you're doing or where you're located. It also helps safeguard your information against hackers and identity thieves looking to intercept passwords and sensitive data about your online activities.
