Which of the following is the full form of VPN?

The correct answer is Virtual Private Network.

Key Points

• A Virtual Private Network (VPN) is a technology that creates a secure and encrypted connection over a less secure network, such as the internet.
• VPNs are commonly used to protect sensitive data by encrypting internet traffic, making it difficult for unauthorized entities to intercept.
• VPNs are widely used to access region-restricted content, bypass censorship, and protect users’ privacy while browsing the internet.
• Organizations often deploy VPNs to allow employees to safely access internal corporate networks while working remotely.
• VPNs ensure anonymity by masking the user's IP address and routing traffic through secure servers.

Additional Information

• Encryption: VPNs use advanced encryption protocols such as AES-256 to secure data transmission, ensuring it remains confidential and tamper-proof.
• Types of VPNs: Common types include Remote Access VPNs (for individual users) and Site-to-Site VPNs (used to connect entire networks).
• VPN Protocols: Popular protocols include OpenVPN, L2TP/IPSec, PPTP, and WireGuard, each offering varying levels of security and speed.
• Advantages of VPNs: They provide secure communication, anonymity, and unrestricted internet access while protecting against cyber threats.
• Challenges: While VPNs enhance security, they can reduce internet speed due to encryption and rerouting, and some countries have restricted or banned VPN usage.
