What is the purpose of a VPN (Virtual Private Network) in internet protocols?

The purpose of a VPN (Virtual Private Network) in internet protocols is to provide a secure and private connection over a public network, such as the internet. It allows users to access and transmit data securely by encrypting the communication between the user's device and the VPN server. This ensures that sensitive information remains protected from unauthorized access and interception. Additionally, a VPN can also be used to bypass geographical restrictions and access content that may be blocked in certain regions.
