What is a VPN Server? Definition and Functionality

A VPN server, or Virtual Private Network server, acts as a secure gateway that encrypts your internet traffic, providing a layer of privacy and security. Understanding what a VPN server is and how it functions is essential for anyone looking to enhance their digital privacy and bypass internet restrictions.

Overview of VPN Servers and Their Role in Digital Privacy

In today’s digital landscape, maintaining privacy online is becoming increasingly crucial. A VPN server plays a pivotal role in this process by allowing users to connect to the internet through a secure tunnel. This technology ensures that your internet activity remains private and anonymous, as your data is sent through the VPN server rather than directly to the websites you visit. The server acts as an intermediary, effectively masking your IP address and geographical location.

How VPN Servers Encrypt Internet Traffic

One of the most significant functionalities of a VPN server is its ability to encrypt internet traffic. When you connect to a VPN server, your data is scrambled using advanced encryption protocols such as AES (Advanced Encryption Standard). This encryption makes it nearly impossible for hackers, government authorities, or your Internet Service Provider (ISP) to intercept or read your online activities.

VPN servers employ various encryption protocols, including:
