What is the main purpose of a Virtual Private Network (VPN)?

1. To connect to a public Wi-Fi network securely

2. To connect to a private network using public wires

3. To boost internet speeds

4. To create a separate physical network

The correct answer is: To connect to a private network using public wires

The primary purpose of a Virtual Private Network (VPN) is to establish a secure connection to a private network over public infrastructure. This means that when users connect to the internet, a VPN allows them to create a secure tunnel for their data, encrypting it to protect their activities and information from potential eavesdroppers. The encryption ensures that sensitive data remains confidential even when transmitted over unsecured networks, such as public Wi-Fi. When accessing a private network through public channels, the VPN uses protocols to encrypt the data packets being sent and received, making it difficult for unauthorized users to interpret the information. This capability is especially important for businesses that handle sensitive information remotely or allow employees to work from various locations. In contrast, the other options do not accurately represent the primary functionality of a VPN. Connecting to public Wi-Fi securely is a related benefit but not the main purpose. Boosting internet speeds is not a core function of a VPN, as they can sometimes even reduce speed due to the overhead of encryption. Likewise, creating a separate physical network does not align with how VPNs operate because they function electronically and virtually rather than through physical networking infrastructure.
