Introduction to VPNVPN 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. All the computers, mobiles, laptops and other devices connected through this virtual private network can share the data with a secured encryption which cannot be observed by anyone else. That's why it is called a private network. It serves the purpose of security. A typical VPN performs the data encryption up-to 256 bytes. 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 VPNVPN 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.These 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 StructureVirtual 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. It does not matter if he is using a public Wifi or not, his all browsing history is encrypted with several protocols.
Pros/ Advantages of VPNVPN helps us in getting:
- Secure connection
- Better Internet Speed
- Access to the restricted platforms
- Chance to go global
- Rid of censorship
- An untraceable IP
- All international offers
- Secured data log
Secure connectionThe 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.
Better Internet SpeedAs 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 PlatformsWe 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.
Chance to Go GlobalOne 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.
Get Rid of CensorshipIf 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 IPIn 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 OffersAs 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 LogHave 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.
