A Virtual Private Network (VPN) is a technology that creates a secure and encrypted connection over a less secure network, such as the internet. It allows users to send and receive data as if their devices were directly connected to a private network, enhancing privacy and security.
The primary uses of a VPN include:
1. **Privacy Protection**: It masks users' IP addresses and encrypts their internet traffic, making it difficult for third parties, such as ISPs or hackers, to monitor their online activities.
2. **Secure Data Transmission**: It provides a secure channel for transmitting sensitive data, especially when using public Wi-Fi networks.
3. **Accessing Restricted Content**: It allows users to bypass geographical restrictions and access content or services that may be limited or blocked in their region.
4. **Enhanced Security**: It protects against various online threats and potential cyber-attacks by encrypting data and shielding users' online identity.
