What is VPN How to use it


The use of the Internet has increased very rapidly in the last decade and a half. Even all the services like money transaction, shopping, banking, business and trading have become online. So why would thieves and robbers stay behind? They have also come on the Internet. And has made online cheating his new business.

At the same time, such methods of cheating have been discovered that do not ask. That is why online security and privacy has become a big problem. And some security measures have been invented to overcome this problem. One of which is the solution VPN (VPN).

What is VPN

VPN i.e. Virtual Private Network is a network technology that works to convert an unsecured network into a secure network. Also helps to hide the actual location and identity of the user. That is, VPN keeps your identity completely confidential. And protects your data from being hacked. Also it protects your rights of Freedom of Internet . and allowing you to access restricted services and websites.

How does VPN work?

When you enter the URL of a website in your browser and press OK. So first of all your request goes to your ISP i.e. Internet Service Provider . Where all the details like your Online Identity, Device ID, Location and Data Request are checked. And after that you are connected to the server of that website. After that whatever data is exchanged between you and that website, it is all done through the ISP . In this case none of your data remains confidential.

Apart from this, your network is also not completely secure. So that every moment there is a risk of data theft. At the same time, restriction is also a big problem. Which prevents you from accessing Blocked Websites. Overall, you have to deal with problems like Freedom, Privacy and Security. But VPN is the solution to all these problems. Because the working of VPN is completely different. How? Let’s try to understand.

Working of VPN

Suppose you want to open this website of mine from the browser of your Smartphone. So as soon as you type techsevi.com and press OK. Your request will go directly to the VPN Server. And the data traffic that will go in the form of a request from your phone , it will be completely encrypted. And will be sent through a Secure Tunnel . Also, your online identity will be completely secret. Because the data traffic will be sent from the VPN server instead of your Smartphone.

But as soon as your data goes to the VPN Server, it will be decrypted. After that the VPN will send your request to the server of techsevi.com. And after receiving the answer from there, it will encrypt it back. and will send it to your phone via its secure connection. Now the VPN software in your phone will decrypt that data. so that you can read it. This way your ISP will never know which website you visited and what activities were done there?

What is VPN Protocol?

A VPN protocol is a set of rules used to establish a connection between a VPN client and a VPN server . So that data can be exchanged securely between VPN Client and VPN Server. These VPN Protocols are currently being used by VPN service providers :- PPTP, SSTP, L2TP/IPSec, IKEv2/IPSec, IPSec, OpenVPN, SoftEther and Wireguard. But Wireguard is currently in the experimental phase.

How to use VPN?

is very easy. Choose a good VPN Service Provider . And go to its website and download the VPN software according to your system. If you are using Smartphone then download the mobile app from Google Play Store or App Store. On the other hand, if you want, you can also download Chrome Extension. Well, after that create your own VPN account and activate your license by logging into it. Take it! Congratulations! You are all set to use VPN.

Just select your preferred VPN Server or Location. And get connected to the Internet in a world where no one can recognize you. Nor can he keep an eye on you. No one can steal your data. Nor can prevent you from accessing any website. Meaning, you can enjoy the Internet completely free and without worry. And can feel the freedom of the Internet from the heart.

Who should use VPN?

By the way, every person who uses the Internet should use a VPN. But if you use the Internet for normal browsing or light entertainment. So VPN is not that much necessary for you. But if you do any work related to Online Banking, Trading, Cryptocurrency, Government Agency, Security Firm, Data Center or sensitive information. So VPN is not only essential but mandatory for you. And for such things, you must always use a VPN.

Apart from this, if you want to keep yourself safe during internet browsing. Or even if you want to access Blocked Websites, VPN is necessary for you. Now you can decide for yourself whether it is necessary for you to use VPN or not.

1. Privacy

People who are always worried about their privacy. A VPN is a great option for them. Because VPN hides the actual location and identity of the user. Also hides its IP address . So that he can do his work by being completely anonymous. That is, which website did he visit? What did you see there? What did you download? No one knows this.

2. Security

It is also a fact of the Internet that news like Online Fraud, Scam, Hacking and Data theft are heard every day. In such a situation, using a VPN becomes even more important. Because VPN gives you online security. It provides you Secure Connection . Also encrypts your data and protects it from hackers.

You must have experienced slow internet speed on certain websites. Actually it is called Bandwidth Throttling or Data Throttling . It slows down your Internet Connection. Due to which there is a very bad effect on the performance. But VPN is able to overcome this problem. Because VPN encrypts your Internet traffic, which gives you high performance.

4. Bypass Restriction

VPN allows access to restricted services by bypassing the restrictions imposed by the ISP. Also bypasses Geographical Restrictions. With which you can also access those websites which are banned in your country. Like if I change the visibility of this article to India, it will be visible only in India. Will not be visible in any other country. But with the help of VPN , it can be seen from anywhere, from any country.

5. Freedom of Internet
