You may have seen or heard the term “VPN” thrown around. Virtual private networks popularly known as (VPNs) is a popular tool in the fight for privacy but unfortunately many people don’t really know what they are and how they work. Despite the huge and complex network theory behind VPNs, they are actually remarkably simple and easy to understand and even more easier to use.
A breif note on how the internet works
To understand what a VPN is and how it works, it’s important to understand how the internet and networks works. When two or more devices are able to interact with one another, that can be called a network. Machines interact by sending data to and fro. The internet is just a worldwide network built out of various networks and devices worldwide.
The VPN Graphic Test
When a user accesses a website from a computer or other device, data is exchanged instantenously. This is necessary in order to connect to a website, but it means that observers can also read these packets and know who is visiting a particular site, and what they’re doing there at that moment.
Here comes in VPN
A VPN is at its simplest, a network that requires authentication before a user can access it. So how exactly does a VPN protect all your data? By serving as a sort of launching pad for users before they access sites.
When a user connects to a VPN, a “tunnel” is created immediately. This is a secure and safe line of communication between the computer and the VPN, meaning that outside observers cannot see the data passing between them at that moment. As a security, the data passing through the tunnel is encrypted and can’t be let out. Only the user’s computer and the VPN know the key to the encryption, so when the data reaches its destination, it can be decrypted and returned to its original state. Amazing right ?
This means that even if a hacker penetrate the tunnel, they would struggle to read the data within but can’t because all data are twisted. This secure tunnel blocks out more than just malicious outsiders.
Once you connect to a VPN, you can browse the internet as usual with one major exception: Your computer behaves as if it is located in the network, rather than wherever you are at that moment. This means that when you access a site while logged into a VPN, the data packets sent will never have your own address on them, but instead that of the VPN.
VPNs are a useful security measure and they also serve another purpose. Because your device while logged into a VPN, acts as if it is part of the network, you can log into VPNs in other countries to get around “geoblocking,” the act of blocking access to a site based on where a user lives.
For an example of how one can use VPNs to circumvent geo-blocking, imagine a user in Nigeria who wants to watch videos on YouTube. If this user were to log into a VPN based in the United Kingdom and access YouTube, the site and anyone observing their activity will recognize them as being in the United Kingdom, where the VPN is located. That is while hackers also make use of it so as not to track them.
How to start using a VPN
Now you know how a vpn works, the question arises: how does one get started using them? Despite each and everything that goes into making a VPN work (tunnels, encryption, and others.) for you it’s as simple as logging in — meaning you’ll need the right credentials.
Start using a VPN in three easy steps:
Download your VPN app(amaze vpn,hideman, express vpn and any of your choice)
Select your plan.
(For example, get ExpressVPN app for your computer or mobile device.
Set up your VPN service. ExpressVPN apps are quick and easy to setup….)
Then Connect to a VPN server. Connect to any of 145 locations in your own vpn app and enjoy the internet with good privacy and security!
So easy and simple once you have the app
The dangers of using a VPN
VPNs can be very useful but they are not without drawbacks. The most immediate problem with VPNs is that they can cut-back your download speeds. Remember as we earlier said that data passing between the user and the VPN is encrypted. The data must also then be decrypted upon reaching its final destination. If you are trying to download a software or game, for example, the bits of data will be encrypted and sent down the tunnel. When they reach , your pc must then decrypt them, and this can take noticeably more time. The speed can also be impacted by how far away the VPN servers are from you. As such, try to avoid connecting to a VPN when playing games or doing any other activities that needs a fast connection.
An additional problem with VPNs is that some larger websites have decided to crack-down on them. Netflix is probably one of the greatest example. In order to keep foreign users from accessing its U.S library, Netflix routinely blocks users if it detects they are all coming from a VPN. This does not only apply to people trying to get around geoblocking. If you live in the United State and try to access Netflix through a VPN, the site will detect it and block access.
VPNs are a great option for anyone looking to protect their own privacy online. They are not foolproof however, so take care when using one or any. Be aware of your country’s surveillance laws and the privacy policies of any VPN you make use of.
