Often we have to sign in on these platforms for this kind of activity, where we have to give our personal details. If you are giving your details online then it can be quite risky.

VPN or Virtual Private Network is a kind of encrypted connection with the help of which you can make a secure connection with any other network over the Internet. That is, you can hide your presence.

Whenever you search any website or any content on the internet, you can connect with it with the help of your internet service provider.  Your ISP assigns you a unique IP address and whenever you access a site, you get identified because of that IP address and your location is known.

But as soon as you connect VPN with your internet, it makes a secure connection for you and now if you access any site, then that site cannot identify you.

This happens because your VPN server keeps changing your IP address continuously and also changing your location. This makes it difficult to identify you.

VPN – Its full name is Virtual Private Network.  It is a private network that is based on a public network such as the Internet but is secure.  In it, the traveling data is encrypted.  It is made safe by using tunneling protocols and security procedures.

  Tunneling or port forwarding encrypts the data when it is sent and decrypts when it needs to be received.  Using this we can keep our browsing on the Internet safe and can also do work from home / anywhere.

The classification of VPN is as follows –

Remote Access VPN –

See in the picture, this is the internal network of a company based on the Internet, regional offices are connected to the company’s main office and all share information and resources among themselves. 
Suppose an employee is out of his office but has to use the resources of his office, then how will he do it?  For this, every employee is given a username and password.  Once verified by the VPN gateway, that employee can use the office’s resources.  IP Security (IPsec) or Secure Socket Layer (SSL) is used to make the network secure.


Nord facilitates VPN to home users; 

Software like Norton and Tunnel Bear do.  These software create an encrypted connection between the client and the server in which the data travels.  Internet browsing through this is safe.

On opening such a blocked website, we get a notice that this website has been blocked by the Government of India.  And the reason for being blocked a bit is also written.  We see this type of situation only when we open a copyrighted website.


For example, if we want to download a movie or web series, then such website is blocked by the internet service provider due to copyright.  So what can we do in this case so that it can open a blocked website.

So we can open these sub-blocked websites easily through vpn.  Vpn flower form is virtual private netwark.  This means that it is your personal network.  Through which you can keep your identity secret too.

What is VPN?

VPN (virtual private network) is a network that secures private network and wifi.  Which prevents our personal data from being stolen from hacker.  In this, the network company gives you an ip address and password so that you can use this network from anywhere in the world.

All data from VPN remains secure and safe whether it is being imported or not.  You can use VPN from both computer and mobile, so that your data is safe, with VPN you can transfer your data without being hacked and your data is also safe.

Let me tell you that your data from VPN is not only safe, but you can also use it to visit or visit websites which have been blocked by the government.

Most of the big companies use VPN network or big websites use it so that they can secure their data and no hacker can hack and steal that data.

How does VPN work?

Whenever we access any site using VPN, it hides our IP address, so that your personal data is not only secure, but you can also access that website.

Which your country has blocked such as facebook is banned in China so that whenever you access facebook on internet, your network is connected to the local network and the local network has banned facebook then at that time  But in China you cannot open facebook .

When you connect your mobile or computer to VPN then it gets connected to a special private network which makes your personal data secure and device is connected to VPN.  You block website i.e. as I have given you the example of China, you can also share your details by accessing facebook in China, even if you are connected to VPN.

This will hide your history (but again, you cannot be completely anonymous, depending on many other reasons, such as their terms and conditions).

A VPN masks your real IP address.  That is, it puts a mask in front of your IP address (you can say it in easy language). It can be identified.

VPN  is legal in many countries and it has been declared illegal by many countries.  That is, there is a VPN Ban.  Like we have PUBG and Tik Tok Ban here.

30 countries have banned VPNs.  Which includes countries like China, North Korea, Russia, Iraq, Turkey.  You must have already known that China will be on this list.

VPN also prevents hackers  to a great extent.

The full form of VPN is Virual Private Network.  You would know this.

With VPN you can access Blocked Website.  Just like Tik Tok’s website is not opening, just use a VPN and then have fun.  Well try not to do that in truth.

Unrealistic Private Network (VPN) extends a private network into a public network, and enables users to send and receive data over a shared or public network as if their computing devices are directly connected to a private network.  Therefore applications running in a VPN can benefit from the functionality, security, and management of private networks.


VPN technology was developed to allow remote users and branch offices to safely access corporate applications and other resources.
  To ensure security, data will travel through secure tunnels and VPN users will use authentication methods to gain access to the VPN – including passwords, tokens, and other unique identification methods. 

In addition, Internet users can secure their transactions with a VPN to connect to a proxy server to prevent geographical restrictions and censorship, or to protect personal identity and location to remain anonymous on the Internet.
