What is a VPN and What Does It Do? Read the Full Explanation Here!

In today’s digital era, online security and privacy have become increasingly important as cybercrimes continue to rise. One of the tools commonly used to protect personal information on the internet is a VPN. But what exactly is a VPN and what is its function?

Definition of VPN

Simply put, a VPN (Virtual Private Network) is a network that ensures the safety of users’ information while browsing the internet. Using a VPN, data sent and received between the user’s device and the server is encrypted. This means that the user’s information cannot be easily accessed by unauthorized third parties.

Besides security, a VPN also offers the advantage of accessing more online content. With a VPN, users can change their virtual location, allowing them to access websites that are typically only available in certain regions.

Functions of VPN on Mobile Phones

VPN serves several important functions, including:

1. Security and Privacy
   One of the main functions of a VPN is to keep data safe. By encrypting information, a VPN protects users from cyber attacks, especially when using public Wi-Fi networks. This is very important for those who often work in public places like cafes or airports.

2. Masking IP Address
   A VPN helps hide the user’s real IP address, making their online identity harder to track. This is beneficial for users who want to maintain privacy while browsing or accessing websites that might be blocked in their country.

3. Accessing Restricted Content
   Many streaming services and websites restrict content based on country. With a VPN, you can select a server in another country, allowing access to content that would otherwise be unavailable in your home country.

4. Avoiding ISP Throttling
   Some Internet Service Providers (ISPs) implement speed controls that can slow down user internet speeds. Using a VPN can help bypass these restrictions and enjoy more stable internet speeds.

How VPN Works

A VPN creates a secure “tunnel” between the user’s device and the VPN server. Data sent through this tunnel is encrypted so that only the user’s device and the server can read it. Once the data reaches the server, it is sent to its final destination using the server’s IP address instead of the user’s original IP.

This way, a VPN not only protects user data but also enables access to content restricted by region. By encrypting information and hiding the real IP address, a VPN helps maintain online privacy.
