What does a virtual private network (VPN) primarily provide?

A virtual private network (VPN) primarily provides a secure and encrypted connection between a user's device and the internet or a remote server. This secure connection is achieved through various encryption protocols, which prevent unauthorized access to the data being transmitted over the network. By encapsulating data within a secure tunnel, a VPN ensures privacy and security, safeguarding sensitive information from potential eavesdroppers, especially when using public Wi-Fi networks.

While aspects like bypassing firewalls or improving data transmission rates may be secondary benefits of a VPN, they do not define its primary function. The core purpose is to create a secure pathway for data communication, making option A the most accurate representation of what a VPN offers.
