What are virtual private networks (VPNs), and how do they work?

A Virtual Private Network (VPN) is a technology that allows you to create a secure and encrypted connection between two networks over the Internet. It provides you with a private network within a public network, like the Internet, by creating a virtual tunnel that encrypts your internet traffic and hides your IP address.

A VPN works by routing your internet connection through a remote server run by a VPN provider. This server acts as a middleman between your device and the internet, encrypting your traffic and hiding your IP address. When you connect to the internet through a VPN, your online activity is hidden from your internet service provider (ISP), hackers, and other prying eyes.

VPNs can be used for various purposes, such as protecting your privacy online, accessing geo-restricted content, and securing your internet connection while using public Wi-Fi networks. Many businesses also use VPNs to allow remote employees to securely access company resources.
