The acronym 'VPN' stands for Virtual Private Network, which is used to create a secure connection over the internet. VPNs encrypt data transmitted between devices and servers, thereby protecting users' privacy and confidentiality. This technology is particularly useful in safeguarding sensitive information when using public or unsecured networks. Additionally, VPNs enable users to bypass geographical restrictions and access content that may be blocked in certain regions. By connecting to servers in different locations, users can maintain anonymity online while ensuring a secure browsing experience.
