Computer Network Basics Questions Medium
A VPN, or Virtual Private Network, is a technology that allows users to create a secure and encrypted connection over a public network, such as the internet. It enables users to access and transmit data securely between their devices and a private network, even when they are connected to a public network.
By using encryption protocols, a VPN ensures that the data transmitted between the user's device and the private network remains confidential and protected from unauthorized access. It also provides anonymity by masking the user's IP address, making it difficult for anyone to track their online activities.
VPNs are commonly used by individuals and organizations to enhance their online security and privacy. They are particularly useful when accessing sensitive information or when connecting to public Wi-Fi networks, which are often vulnerable to cyber attacks. Additionally, VPNs allow users to bypass geographical restrictions and access content that may be blocked or restricted in their location.
In summary, a VPN is a tool that creates a secure and private connection over a public network, providing users with enhanced security, privacy, and access to restricted content.
