A virtual private network (VPN) is a technology that creates a secure connection over the internet between your device and a remote server. It encrypts your data, making it difficult for others to intercept or access your online activities. This is especially useful when using public Wi-Fi networks, as it helps protect your personal information from potential hackers. VPNs also allow users to access content that may be restricted in their region. By connecting to a server in a different location, you can appear as if you are browsing from that area, enabling access to websites and services that may be blocked in your country, such as certain streaming platforms or social media sites.
