Introduction to VPN 

VPN is pronounced as Virtual Private Network. As its name suggests, VPN is a private network connection which serves the purpose of data sharing, privately, among several connected devices.

Data encryption means that your original data is being transmitted into a different complex language which needs to be decrypted for understanding. That's why, when you surf the internet via VPN, all your data log is encrypted and no internet service provider can see the actual data. They just see a connection between a random IP and the VPN server. The encrypted data seems garbage to them. 

History of VPN

VPN was introduced in 1996 just for the sake of sharing the team data, remotely, via private network. It made the team eligible to connect the company's device via secured connection. Later, many military and government sectors shared their resources and their devices via virtual private networks so that any core member of the department could access the data anywhere online.VPN, Virtual Private Network, guide for VPN, VPN Guide,Virtual Private Network GuideThese private networks made sure the data encryption as well. No other internet user or service provider could actually see their transaction details. That's how the VPN appeared as a handful yet secured network. With the passage of time, a corporate sector adopted this private network method as they could not afford to reveal their specific business models and strategies online with anyone; therefore, they made their own virtual private networks to deal with their international staff via private network. 

VPN Structure

Virtual private network means a private network access to a public network connection virtually. There are different protocols used in building a secured VPN. Whenever a person is connected through a VPN, his browsing history and login details won't be accessible via public network.

  • Secure connection
  • Better Internet Speed
  • Access to the restricted platforms

Secure connection

The very first and foremost usage of the VPN is building a secured line of data transmission which cannot be traced, manipulated or hacked by any service provider. All the data which is transmitted by a VPN is encrypted in several layers and the service provider can just see a connection between them, not the actual data which is being transferred. That's why most of the banking sectors and e-commerce stakeholders have their own VPNs. Otherwise, all the private credentials can be hacked or manipulated with some medium level hacking. VPN, Virtual Private Network, guide for VPN, VPN Guide, Virtual Private Network Guide

Better Internet Speed

As you have known that VPN is a private network, so it works as a dedicated server between the both ends. We may receive lag in our public network connections due to a burden of overload traffic but the VPN works as a sole private network which is dedicatedly available to you. Regardless of a normal public connection speed, VPN always offers you a better speed than a public network. That's why many streamers and professional gamers now have to have a premium VPN service for the best speed. 

Access to the Restricted Platforms

We are living in a highly diplomatic and highly competitive era. Many international countries and brands have to restrict their services due to their diplomatic policies like China and Saudia won't allow you to use Facebook and Google etc. In the same way, some countries won't support the PayPal and Netflix streaming services. If you are traveling or staying there for a while, you still can access your PayPal and Netflix subscription there with the help of VPN.  If you still want to use any international service without any local restrictions, you need to have a VPN service.VPN, Virtual Private Network, guide for VPN, VPN Guide, Virtual Private Network Guide

Chance to Go Global

One of the most fascinating things about VPN is about connecting to an internet from any country's local network. You can select your favorite county's network to connect with and then all your data surfing and browsing would be done with that particular network. 
Most of the time, any internet geek or E-commerce geek chooses VPN to collect data and statistics for an international forum. For example, whenever you type a certain keyword in your browser, you will see some top suggested queries by your browser. Those top suggestions are based on most common search queries from your nearest areas. Hence, you can connect to another country's network via VPN and collect a different data set by searching the same query in your browser. It would give you top search results from that particular location. Any SEO guru can do this to master the keyword finding technique. Probably most of the keywords finding tools perform the same algorithm to gather the top ranking keywords in different parts of the world.  

Get Rid of Censorship

If you ever feel rejected, restricted by the national censorship laws and some international forums and you just can't share any bold content or speech of your desire. You can achieve that freedom of speech after getting connected with any of a VPN service. You can then easily share your ideas and content from a different location. 

An Untraceable IP

In a normal routine, you are easily traceable and trackable of your all activities via your internet devices. All your banking details and your bank transaction can be hacked with ease on a public network. You can even be traced with some medium to advance hacking tools. Hence, you are nothing but a caged person in this miserable public network connection. So, you may get an untraceable IP each time after getting connected with the VPNs. Each time you get connected to the VPN, you get a new IP address which cannot be traced back to your device. 

Redeem All International Offers

As you have already understood much about VPN, you should be aware of the fact that you can change your logged in location with the help of VPN. Now here comes an exciting part. Many companies and brands present the special deals and discounted offers for specific countries or regions on some specific local festivals. If you have a VPN service, you can easily redeem the discounted price after getting logged in from that particular location. In another case, you can even purchase online from different locations to have a fair deal. For example, AliExpress provides a different rate for Chinese than Europeans. 

Secured Data Log

Have you ever wondered about the internet ads process? How do they belong to you every single time? How can they appear at the right place at the right time? How is it possible for those advertisers to know your personal interests and your personal needs?Well, it is an alarming yet awakening fact that every single free social media service provider keeps logging and storing your personal data from your device. Whenever you download the free apps, they ask the permissions to access your microphone and camera. There you fall into a trap. They can know every single thing about yourself through your device. They sell that particular data to those third party apps, so they can lure you with the most relevant necessities. That's how the whole online advertising model works. That's how all these free apps are still able to provide you so called free services, because you are not paying for their products but you are yourself a product. It is what it is.VPN, Virtual Private Network, guide for VPN, VPN Guide, Virtual Private Network Guide

That's why government institutions and your national internet service provider keep tracking your internet activities all the time. If any fraudulent or terror activities are to be done somewhere, they try to trace it via their logged data and eliminate the threat before a threat eliminates us.That's why many countries won't encourage the VPNs as they consider it as a risky approach for common civilians. If it is encouraged openly, then every single person would be doing it and they can't differentiate between anyone because they won't be able to decrypt the encrypted surfing data. Anyone with bad intentions would be a major threat if he would be using the VPN each time before going to the internet. That's why, all the security institutions won't allow any open usage of the VPN. They are interested in tracking your records for your safety;however, you won't be having your free private life.

They just redirect your internet requests to the private network and all the responses from the public networks against your search queries revert back to you from the same private network connection. There is no direct network connection between the public network and your device. You can get a new random IP address each time while connecting to that free VPN. So, your location is untraceable.These free VPNs are most favorable towards newbies and freebies. Almost all the teenagers use such free VPNs to stream their favorite content platforms like Netflix, Hulu and Sonyliv etc. The major benefit of such VPNs is that they won't cost you some extra bucks but they are not much feasible as well. They are usually slower than premium ones because many people use their free services and their server is usually down due to heavy traffic. Moreover, their security is not as much safer as it should be. As they also have an advertisement revenue model for their return of investment (ROI), you are still on the verge of losing all your data online to some specific advertisers. That's why you observe many ads even on VPNs. So these are not trustworthy for secured businesses. They are just valuable for youngsters for steaming the restricted games and apps free of cost. 

Premium VPNs

Premium VPNs are dedicated VPNs for your network connection. They are not rushy as there are no freebies there on their server. Only mature and serious peeps buy their membership to have either a better speed of internet or a much safer protection for their online surfing. In such premium VPNs, several layers of VPN protocols are added and your data is made fully encrypted. Further, your one session data expires- once you logged out from that private connection. That's the most attractive part to buy a premium service of a VPN as it gives you full control and assurity about your protected internet surfing. These premium VPN services have several backup servers in their end, so their speed is  rarely compromised. Such VPNs give freedom of speech and a free life- a true meaning.
