VPN
VPN (Virtual Private Network) is a technology that creates a secure, encrypted connection over a less secure network, such as the internet, to protect data transmission and provide anonymity. It allows users to access private networks remotely and masks their IP addresses by routing traffic through servers in different locations. This is commonly used for secure remote work, bypassing geo-restrictions, and enhancing online privacy.
Developers should learn VPN technology when building applications that require secure remote access, such as corporate networks, or when implementing features that depend on location-based services and privacy. It's essential for scenarios involving sensitive data transmission, testing geo-blocked content, or ensuring compliance with security protocols in distributed systems.
