What is a VPN: The Way It Works and Advantages It Offers

VPN has become a buzzword, which you may hear almost every day but not fully understand its purpose and the range of opportunities it offers. The following information provides the main knowledge for understanding the technology and becoming a tech-savvy user.

Let’s clarify the term and find out why it was invented.

Virtual Private Networks (VPN) were originally created for large businesses and corporations to provide their employees with access to particular computers from various locations without compromising security.

For instance, Nike’s headquarter is located in Beaverton, Oregon, the USA, but the company does overseas manufacturing in China, India, South Korea, Thailand, and Vietnam. In Beaverton, all the main computers are connected to Nike’s server via a network of cables, which are physical, highly secured, and hard to hack.

Running the cable from the USA to Thailand, to let an employee from the Thai factory connect to Nike’s private network, is just impossible. That is why creating a virtual private network — like a virtual cable between the countries — is what they need!

So how does it work?
