What is a VPN?

• A. A Virtual Private Network that creates a secure connection over a less secure network
• B. A secure digital payment system for online transactions
• C. A method for data encryption on local networks
• D. A program for managing firewall settings

Answer: (A)

A Virtual Private Network (VPN) is a technology that creates a secure and encrypted connection over a less secure network, such as the Internet. By using a VPN, users can protect their private web traffic from snooping, interference, and censorship. The VPN establishes a secure tunnel between the user's device and the VPN server, which can then route the traffic to the Internet. This means that any data transmitted over this connection is encrypted, making it difficult for outside parties to intercept or monitor the communications. The context of why other options do not fit includes that a VPN is specifically focused on creating a secure connection across untrusted networks, while the other options target different aspects of digital security and networking. Secure digital payment systems pertain to transaction security rather than network connections. Methods for local data encryption do not usually involve creating private networks, but rather focus on securing data stored on devices or transmitted within a local area network. Programs for managing firewall settings relate to controlling network traffic but do not constitute a VPN’s function of creating secure connections.
