FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -VPN stands for “virtual private network”-a service that helps you stay private online. A VPN establishes a secure, encrypted connection between your computer and the internet, providing a private tunnel for your data and communications while you use public networks.

Detailed explanation-2: -A Virtual Private Network (VPN) adds security and anonymity to users when they connect to web-based services and sites. A VPN hides the user’s actual public IP address and “tunnels” traffic between the user’s device and the remote server.

Detailed explanation-3: -It is an encrypted connection over the Internet from a device to a network. It creates a private network to separate the user’s traffic from the rest of a public or shared network. The encrypted connection helps ensure that sensitive data is safely transmitted.

Detailed explanation-4: -VPN is basically a mechanism to simulate a private network over a public network. It includes the implementation of encryption and authentication to connect to the network and access the remote system. A Proxy server does not imitate a private network over a public network.

Detailed explanation-5: -VPNs are primarily used for remote access to a private network. For example, employees at a branch office could use a VPN to connect to the main office’s internal network. Alternatively, a remote worker, who may be working from home, could need to connect to their company’s internet or restricted applications.
