What does a Virtual Private Network (VPN) enable users to do?

A Virtual Private Network (VPN) is designed to create a secure and encrypted connection over a less secure network, such as the Internet. This technology allows users to send and receive data as if their devices were directly connected to a private network. By utilizing a VPN, individuals can ensure that their online activity remains private and secure from potential eavesdroppers, such as hackers or government surveillance.

When connecting to a private network (like a corporate network) over a public network (like Wi-Fi hotspots in cafés or hotels), the VPN encrypts the data transferred between the user’s device and the private network. This encryption protects sensitive information, making it much harder for malicious actors to intercept and exploit data.

While the other options touch on different aspects of technology, they do not accurately describe the primary function of a VPN. Accessing local files offline pertains to file storage, sharing files in real-time relates to collaboration tools, and enhancing surfing speed is generally not the core focus of VPNs, as they often have the potential to slow down internet speed due to encryption processes. The correct choice highlights the secure connection aspect, which is the fundamental purpose of a VPN.
