A VPN, or Virtual Private Network, is a tool that allows you to connect to the internet using a public or private network while hiding your identity from third parties. It's widely used for secure internet access, remote work, and other online activities.
- Secure Connections: VPNs encrypt your internet traffic, making it difficult for others to access your accounts.
- Privacy: You can access private or restricted areas of the internet without your computer knowing.
- Customizable: You can choose which public network you want to connect to and which private network you want to use.
- Real-time Access: You can access the internet and your accounts at any time.

Types of VPNs:
- Client-Server VPNs: You connect to a server that hosts your accounts.
- Server-Server VPNs: You connect to other computers running the same or different protocols.
- Public vs. Private Networks: You can connect to public (like the internet) or private networks (like a local area network or a VPN).
