Q1. What is VPN?

A: VPN stands for Virtual Private Network. A VPN helps you access internet resources remotely, securely, and privately with tunneling technology. You might use a VPN for Enhanced Security, Privacy Protection, and Remote Access.

Enhanced Security: VPNs encrypt your internet traffic, protecting your data from potential eavesdropping or unauthorized access.

Privacy Protection: VPNs hide your IP address and location, making it difficult for websites, advertisers, or malicious actors to track your online activities.

Remote Access: VPNs enable secure access to your home or office network from remote locations, allowing you to access files, printers, or other network resources.
