What is the full form of VPN?
The full form of VPN is “Virtual Private Network“. VPN is a secure and private network connection through the public internet. VPN services protect your personal data, hide your IP address when you use the internet, and let you bypass censorship, content blocks, and website restrictions. Its work is basically to provide an encrypted connection between a device and network so that personal and sensitive information can be transmitted between desired people.
Point-to-Point Tunneling Protocol (PPTP) is one of the oldest and most widely used VPN protocols in existence. Developed in the mid-90s by Microsoft. It generates a tunnel and confines the data packet. Point-to-Point Protocol (PPP) is used to encrypt the data between the connection.
L2TP or Layer 2 Tunnel Protocol is a replacement of the PPTP VPN protocol. This protocol does not provide any encryption or privacy out-of-the-box. It is often combined with another VPN security protocol like IPSec to establish a highly secure VPN connection.
