VPN

The World has become a global village ever since the inception of internet. Nowadays, browsing isn’t just about surfing pages on the internet, it allows you monitor the activities of other users. If you are concerned about your privacy while you use the internet, it is very likely you have come across the term “VPN”. Only a few people know what Virtual Private Network (VPN) is all about. There is nothing complicated about VPN. 

Before we talk about VPN, it is important to first understand the working principle behind the internet. A network is created once a connection has been established between two or more devices or computers. Internet is basically the network created when several computers and devices around the world communicate with each other.

Data is always exchanged when a user accesses online data using a computer or a mobile device. To do this, the user will have to send out packets which contain the address of the sender and the receiver. It then becomes easy for an observer to easily track the activities of a user.

In the simplest term, VPN is a network that requires authentication to be accessed by a user. As an instance, some job sites require passwords and username before it can be accessed. To protect your data, VPN will act as a sort of launching pad that allows users to access such sites. 

VPN secures the data exchanged between computers, thus locking out any external observer. For more security, the data that passes through VPN are encrypted. Encrypted in the sense that the information contained in them, are altered in a certain way. For instance, A becomes B, while C turns to D.

Once the information gets to the end user, it will be decrypted. Should an intruder break into your network, they will be at sea because interpreting your information will be difficult. 

With a VPN, you can still surf the internet, but in a different way this time. It will be as though your computer isn’t located in your actual location, but in the network. When you access a site using VPN, the data packet will not contain your actual address, but that of your VPN.

Why you need a VPN

VPN not only serves to protect your network, it also allows your computer behave as if it is coming from another country. For instance, let’s say you are in Iraq and wish watch YouTube. With a VPN, anyone monitoring the activities around YouTube will see you as being a resident of an American State. 

Now you have had a fair knowledge of VPN, next is to learn how to use it. A good example of VPN is the network of a campus or an office. The smartest way of signing up on VPN is to register with a VPN service provider. Before deciding on the VPN service provider you will finally settle with, it is important to do some research.
