d) To encrypt local files
Answer:
a) To create a secure connection over the internet
Explanation:
VPN (Virtual Private Network) is a technology that creates a secure, encrypted connection over the internet, allowing users to transmit data privately and securely. It is commonly used to protect sensitive information, especially when accessing public Wi-Fi networks.
By using a VPN, a user can mask their IP address and encrypt their online activity, making it difficult for hackers or third parties to monitor their internet usage. This is especially useful for businesses and individuals concerned about privacy.
VPNs are also used to bypass geographic restrictions, enabling users to access content that may be blocked or restricted in their location.
