What does a Virtual Private Network (VPN) do?

A Virtual Private Network (VPN) is primarily designed to create a secure tunnel between the user's device and the internet, encrypting data as it travels through this tunnel. By encrypting the traffic, a VPN ensures that sensitive information, such as personal details, passwords, and browsing habits, is protected from eavesdropping and unauthorized access. This encryption process safeguards data from potential threats, especially when using public or unsecured networks, thereby enhancing overall privacy and security.

The fundamental purpose of a VPN is to allow users to transmit data securely over the internet, ensuring that their online activities are private and protected. This functionality is crucial for individuals and organizations that need to maintain confidentiality and security for their communications and data exchange.

While other options may seem plausible at first glance, they do not accurately encapsulate the primary function of a VPN. For example, the second option suggests that a VPN allows internet access without a browser, which is misleading as a VPN operates at the network level and is not dependent on a browser for functionality. The third option asserts that a VPN connects multiple devices without encryption, which contradicts the fundamental purpose of a VPN; encryption is a core feature. Lastly, the fourth option implies that a VPN creates an isolated network environment, which may be
