What is the function of a VPN?

• A. To speed up internet connections
• B. To create a secure connection over the internet
• C. To increase data storage capacity
• D. To manage incoming email traffic

Answer: (B)

A VPN, or Virtual Private Network, functions primarily to create a secure connection over the internet. This is achieved by encrypting data transmitted between the user's device and the VPN server, effectively protecting sensitive information from interception by third parties, such as hackers or surveillance entities. The encryption facilitates a private, secure communication tunnel that is particularly valuable when using public Wi-Fi networks.

Furthermore, VPNs also enable users to mask their IP addresses, which enhances online privacy and allows access to geographically restricted content. The security aspect of a VPN is crucial for individuals and organizations seeking to maintain confidentiality and integrity in their online activities, making option B the accurate description of its primary function.
