Virtual Private Network (VPN)
Definition: A network protocol that establishes a secure and encrypted connection between a user and a network over the public internet. VPNs are often used to access regionally-restricted content, protect online privacy, and ensure secure communication over unsecured networks.
Key Features:
Encryption: All data sent over a VPN is encrypted, protecting it from prying eyes.
Anonymity: VPNs can mask the user's IP address, making their online activities anonymous.
Location Masking: Users can spoof their geographical location by connecting through servers in different countries.
Common Applications:
Privacy: Protecting online activities and sensitive data from third parties.
Accessing Blocked Content: Bypassing geographical or institutional restrictions.
Secure Communication: Safe browsing on public Wi-Fi networks.
