What is a VPN[Virtual Private Network]

The internet is one of the most important discoveries of the modern world; the internet contains everything you want and need. It is a huge step in bringing the world together.

In the right hands, it is a source of vast and never-ending knowledge. But as it turns out, with more things available to people, a need arose to put some regulations on the internet.

There were laws set up to protect the citizens of the internet and prevent piracy. The countries came up with their own set of rules to regulate the internet.

As a result, some specific websites were blocked only in some countries. So if one website is blocked in one country, it might be working in any other country. It posed a problem for the people who wanted to use the internet freely. Then, VPNs came to help them.

Virtual Private Network, or VPN, is not a new term for netizens. They regularly use VPN for various functions like unblocking torrent websites, watching online content, etc.

Not only this, but VPN also is helpful for business people who have to stay in contact with their office even if they are working from a different location.

VPNs are nifty tools when you want to surpass the geo-restrictions and use the internet for fun or business-related work. Also, it protects your anonymity and data from theft to keep you safe on the internet.

Now, a question arises how a VPN does all this? How does a VPN work? Let us try to understand the intricate working of VPN in simple terms.

How do VPNs work?

Every device has an IP address. That IP address becomes your virtual address when you are online. Your IP address is traceable to find you and your device.

What a VPN does, is changes your IP address virtually. It shows your location in a different country. It allows you to access the internet of that country.

When you turn on the VPN and use the internet, VPN becomes the mediator of your data. So all of your data passes through a VPN. The VPN assigns you an IP address from any country of your choice.

So, it seems that you are sitting in that country and using their internet. Since the VPN is your source now, geo-restrictions are gone.

The data you are supposed to receive also passes through this VPN. During this passage, all of the data turns into gibberish.

So even if anyone tries to intercept and steal your data, all they will receive is meaningless strings of letters and characters.

So VPN shoots two birds using a single stone – passes geo-restrictions and protects your data and anonymity. For these features, VPNs are famous among the people who want to protect their internet freedom and safely use the internet.

Pros and cons of VPN

Just like other things, there are pros and cons of VPN as well. Let us take a look at the advantages and disadvantages of using a VPN-


  • Protects your data online
  • Allows you access to blocked websites in your region
  • It lets you watch region-restricted content on various streaming platforms
  • Keeps your online activity hidden from your internet service provider
  • Maintains your anonymity online


  • Ruled illegal in many countries
  • Insufficient knowledge of encryption
  • Unstable connections

As its pros heavily outweigh its cons, VPN apps stay the favourite of netizens to make sure of their online safety and data protection.

Uses of VPN

From entertainment to business, VPN has several uses that make it a helpful app. Here are some of the widespread applications for VPNs in both the private and business sector.


Online multiplayer games are on the rise. What started just as a hobby; has become a career path for many people. People spend hours playing games and making their names.

They love to games with other better players to improve their game. But geo-restrictions sometimes do not allow them to join in regional rooms of any other country. It is when using a VPN app helps them.

Using the VPN, they can pass these restrictions and play games on foreign servers with minimum lag. It allows gamers to improve on their game and make their name in the gaming community.


It means a huge network of people, where they can download files from each other’s devices. Sometimes, the files people want to share can get large.

That makes it difficult to share it, especially if it is to be shared across the world. It is where torrenting comes in. It allows users to share files via the internet worldwide.

The speed is dependent on how many people are sharing that same file. Torrenting is also used to download movies, software, TV shows, games, etc.

Now, some countries have blocked torrenting websites. Users take the help of a VPN in this situation. They use VPN to cross the geological boundaries and use torrenting websites from a country where they work.

Unblocking Geo-Restricted Content

Everyone loves to watch content on streaming platforms. Since the pandemic, online streaming of shows has become popular among every age group of people.

They spend their working, and at night it is streaming time. They love to watch movies and shows in their homes. These streaming websites, and apps, generate revenue, and people get their entertainment.

But here comes a problem. Every country has its media laws, which online streaming platforms have to follow. As a result, some content gets blocked in some countries.

It may include some popular and critically acclaimed shows. To stream these contents, people turn to VPN. VPN allows them to watch content that is available only in some specific countries.

By changing their IP, they change a device’s location. Thus, it finds a way around the geo-block in some countries.


Working never stops for some people. Even if they are away from the office, they need to stay connected with their office; sometimes, they even have to work remotely.

Large companies work on their private network. They have their network set up in their offices around the world, and they have to keep these offices interconnected.

VPN helps companies to set up this web. One main router acts as a VPN client, and other routers in other offices become the repeater. Employees have to log into this private connection to get connected to the company’s network.

VPN can also link multiple companies to a single network by configuring their routers. Also, employees can get login credentials from the IT department to continue working from home while staying on the company’s private network. It keeps the company’s data secure and prevents any breach from hackers.

How to use VPN?

Language and working of a VPN may sound very technical, but using it is contrastingly easy. All it takes is a few taps on your device to make your device secure. Here is how you can set up a VPN service in your device easily-

  1. Buy a subscription to your preferred VPN service. We prefer NordVPN because of its amazing features.
  2. Install its app on your mobile, tab or your computer.
  3. Run it and choose the country of your choice.
  4. If you don’t have any preference, directly run it.

That is how you can run a VPN on your device.
