What does a Virtual Private Network (VPN) primarily provide?

Physical access to networks
Encryption for secure data transmission
Data storage solutions
Increased network speed

The correct answer is: Encryption for secure data transmission

A Virtual Private Network (VPN) primarily provides encryption for secure data transmission. This technology establishes a secure and private connection over a public network, such as the internet, using encryption protocols. By encrypting the data being sent and received, a VPN protects it from eavesdropping and interception. This is particularly important when using unsecured networks, such as public Wi-Fi, where sensitive information could otherwise be exposed. The encryption ensures that even if the data packets are intercepted, they cannot be easily deciphered by unauthorized users. This capability is essential for maintaining confidentiality and integrity while accessing resources remotely or communicating over an untrusted network. While some might consider aspects such as data storage solutions or increased network speed relevant, those are not primary functions of a VPN. The main purpose remains the secure transmission of data through encryption, enabling safe internet usage and protecting user privacy.
