Virtual private network
A virtual private network or VPN for short, is a way of connecting a computer to a remote network. Most people using computers connect to the World Wide Web using a normal network, such as dial-up or broadband. A VPN is a little bit different. It's commonly used by workers to connect to their work network using a laptop to check their work email and see work websites that cannot be seen on the normal internet.
Similarly, the encryption process allows VPN to offers anonymity by hiding the user and making it very hard for anyone to track them. As a result, VPN helps make one's online activities on the web anonymous and undecipherable.
VPN is often used to access websites that are blocked in some countries, like China. Many people also use a VPN to protect their internet activity while using public WiFi. While VPN usage varies by country, you can see a full list of reasons why, where, and how often people use a VPN at GlobalWebIndex.
VPN can also be used to connect corporate offices to the larger branch offices, also known as site-to-site VPN. This is because direct network connections are impractical between offices that are physically distant.
