VPN stands for Virtual Private Network. It is a technology that allows you to create a secure and encrypted connection over the internet, providing privacy and anonymity while browsing. VPNs are commonly used to access geographically restricted content, protect personal information from hackers and government surveillance, and bypass censorship in countries with strict internet regulations. They work by routing your internet traffic through a remote server, which masks your IP address and encrypts your data, making it difficult for third parties to intercept or track your online activities. There are both free and paid VPN services available, with varying levels of security and features.
