What is a VPN?

A VPN, or Virtual Private Network, is primarily designed to enhance security and privacy when users connect to the internet. By creating a secure tunnel for data transmission, a VPN encrypts your internet traffic, making it more difficult for hackers, your internet service provider, or government entities to monitor your online activities. This is particularly useful when using public Wi-Fi networks, where the risk of data breaches is heightened.

Moreover, a VPN can help users access content that may be restricted in certain geographical locations by masking their IP addresses. Overall, the main function of a VPN revolves around providing a secure and private way to use the internet. Other options do not accurately represent the true nature and purpose of a VPN, either focusing on aspects unrelated to its main function or misrepresenting its purpose.
