If you spend time on the internet, chances are you have seen a pop-up advertisement somewhere for a VPN. But what exact is a VPN, how does it work, and do you really need to spend even more money on subscription services? Here is the low-down.
What is a VPN?
Firstly, VPN stands for virtual private network. Essentially, it is a private network that uses virtual connections from the internet and encrypts all traffic and information; this gives uses a more secure connection to different websites.
How does it work?
A VPN creates a tunnel from your computer, laptop, or smartphone to the internet. It then encrypts all the data, masks your IP address, as well as your location.
Why would I want one?
VPNs can be used for business purposes so that employees are connect remotely to private servers. Additionally, they are also used by the general public for people who worry about internet security and privacy. One of the more exciting uses for many, however, is that it can help you get around regional restrictions. For example, if the American Netflix has better programs than the South African version, using a VPN can allow you to sign in to the American Netflix by tricking your computer into thinking you are in the United States.
