What does VPN mean? VPN connection what is it?
Being able to comprehend how does VPN work might seem hard, but the truth is, it isn’t. First of all, the definition of VPN: What is a VPN? What is a VPN connection? According to Wikipedia (yes, even teachers use Wikipedia, what do you guys think?), a virtual private network (VPN) extends a private network across a public network, such as the Internet. It enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network.
Well, that didn’t help much, did it? The problem with sites such as Wikipedia, is that it relies on the reader on already having some knowledge on the topic they are researching. In this case, a lot of prior technical knowledge. Though after reading this article, if you’re still interested and wish to learn the intricacies of how virtual private networks work, then I would suggest you ready yourself for a deep dive, and sites such as that Wikipedia page will go into routing, User-visible PPVPN services, layering services, so on and so forth. But for now, let’s continue with this 101 class.
So, let’s find a better way to put it. It is basically a network. And this network is virtual in that it establishes a virtual bridge between VPN users (you, for example) and a server (located anywhere on earth). Finally, these network connections are private because to get access, you need to have an account with login credentials (username and password). It also differs from a leased line since it offers encryption and authentication.
What is VPN client? So, you connect to a server and then this server connects to the Internet for you and makes sure that you have a secure connection. That’s it. The client itself is basically just the app and setting up a VPN is even simpler.

VPN and security
If you are missing the point and you’re still somewhat confused about what is a VPN connection, what is a VPN, how does vpn work or what does a vpn do. Don’t worry, it is just the beginning. And you will soon have a better understanding and knowledge of what a VPN is and have VPN explained. Now let’s take a tiny look into a bit of internet history. Does anyone know why virtual private networks were created in the first place? No? Here’s a clue: it has something to do with business…Okay, still nobody?
Originally, companies created VPNs to protect their communications from industrial espionage. Because there are increasingly simple ways to intercept data travelling to a network. Have you heard of MAC spoofing and Firesheep for example? Two solutions to hack information.
That’s why a VPN offers an encrypted connection from point A to point B. A VPN client uses an encrypted data transmission and a tunnelling system to securely route the data between these two points. Back and forth. As a result, your data is encrypted and protected. It’s almost like that secret tunnel at the back of your castle that leads you safely away through the secret mountain passage, and only you and your fellow knights know about it. VPN explained yet?
VPN and privacy
Security sounds good, right? What about privacy? Good news: a VPN also means better privacy! Besides, security and privacy typically come hand in hand anyways. Now indeed, the VPN replaces the IP address of your internet connection with the IP address from the server where you are connected. And you can connect to any server that the VPN provider has for you to choose from. Therefore, you can have several different IP addresses. For instance, you may live in London and appear to be in New York with the help of the VPN (or vice versa). So at least when somebody asks you what exactly is a VPN and what is it used for, you can mention that privacy is certainly one of the main reasons as to why they are highly sought after.
To summarize, when you are using a VPN: first, nobody can intercept and use your data. Second, nobody can know which websites you are visiting. That’s all there is to it. Simple and easy on the surface, just as technology should be. Now you are able to answer the question: what does a VPN do or how does vpn work?
VPN and censorship (geo-restricted content)
Being able to understand what does a VPN do or how does vpn work and how it is affected by censorship is especially important when it comes to learning about geo-restricted content and using VPNs to get around them. After all, what is VPN program, what is a VPN, what does a vpn do or what is a vpn connection, if not able to help you bypass these restrictions?
But that’s not all! Indeed, there is another good point related to the privacy method described above. For example, connecting to an IP address from any country means that you can unblock all the geo-restricted content from the country you connect to. Imagine that you want to watch American Netflix from your home in Leeds. Without a VPN, the thought of doing so is virtually impossible. But with a VPN however, you can instantly connect to an American server and easily access US Netflix! American shows from the comfort of your own home with just a few clicks of a button, simple and easy
And it is the same thing the other way round. If you are on a trip to China, with a VPN you can watch UK Netflix from abroad or watch the BBC iPlayer. Furthermore, you can unblock content and get access to censored websites like Facebook or Twitter. So, really, no matter how you look at it and no matter how you intend on using it, you can see how beneficial it would be to your online activity by having a VPN client. With all that being said, it should pretty much answer the question – what is VPN client, what is VPN program and how does VPN work?
What is a VPN? Here’s a fun little fact; most journalists connect to a VPN and use virtual connections to bypass restrictions and censorship when they’re away. That way they can stay free on the internet and make sure that their only activity has a secure connection for their work. Online security is doubly important when you’re a traveling journalist. And when you’re traveling, sometimes you are forced to use public wi-fi in order to get online. This is another area where having access to a virtual private network is extremely beneficial.
To summarize, with a VPN you can protect your data and privacy and access websites and content that are usually restricted. Exercise that freedom!

Several protocols are available today for secure tunnels. The most common ones are:

Is VPN essential?
To understand if a VPN is essential, you have to understand what does a VPN. The great thing about a VPN is that it adds security. And while that is good to have, you might wonder if it really is that important. To cut a long story short, yes, a VPN is important, especially when you consider that your internet security is pertinent. However, when you wonder how does VPN work, you should note that it does quite a lot more than just encrypt your data connection. VPN protection does a lot more as it should be seen as a full service, with every one of those servicing adding a little more value to the entire internet browsing experience. When you ask, what does a VPN do or how does vpn work, from a security standpoint or even a security one, you are simply asking, what is a vpn connection’s work or what do you get from using the VPN mechanism.
What is a VPN?
To know how does VPN work, you should note that with a VPN, you can be sure of anonymity whilst on the internet. Think of it this way, every aspect of the internet has some sort of tracking placed on it. Most people have simply accepted that to be the norm of the world and simply do not care. That being said, there are quite a lot of other that still value their anonymity and privacy. The fact is, even the software specifically designed to secure your information is limited in what it’s able to do. Every one of your connections has to go through a service, enabling that service providers to track you and the fact is every internet provider sells user data.
Having a VPN helps provide an intermediary between your internet provider and you. The VPN basics is that your connection heads first to the VPN server, which enables you to eradicate any avenue for data tracking. Now you are able to answer what is a VPN and what does a VPN do.
