What is VPN (Virtual Private Network), How does VPN works Explained 2018 !

What Is A VPN? : A VPN (Virtual Private Network) is a technology or service that encrypts your Internet traffic and protects your online identity. Or you can say VPN is a popular internet security method, The latter involves technologies that aim to add a layer of security to both private and public networks. It creates a secure tunnel between your computer and the VPN server and All the data on this channel is encrypted, means all network traffic, from voice to text to video, goes through a secure passageway between the client’s computer and the VPN server.

What does a VPN do?

Typically, when you try to access a website on the Internet, your ISP (Internet Service Provider) receives the request and redirects you to your destination. As your Internet traffic passes through your ISP, they can see everything you do online. What’s more, they can track your behavior and sometimes even hand your browsing history over to advertisers, government agencies and other third parties.

Here’s where a VPN comes into play. It redirects your Internet traffic through a specially configured VPN server, hiding your IP address and encrypting all the data that is sent or received. The encrypted data is essentially gibberish to anyone who intercepts it, making it impossible to read. Here is the Top 7 benifits of using a VPN service.

Online Security: Shield your personal data and activity with end-to-end security while browsing the web from any location, on any device.

Bypass Censorship: Get around regional restrictions and other forms of online censorship that block you from accessing certain websites, videos, and more.

Anonymous Browsing: Enjoy truly private browsing from anywhere without being watched by your school, office, or any other third parties.

To use a VPN you need to sign up for a VPN service. These typically operate VPN servers located in various locations around the world. You will also need to download special software known as a VPN client or VPN app. The VPN app connects your device (such as a PC, laptop, or smartphone) to a server run by the VPN provider. All data that travels between your device and the VPN server is encrypted to ensure that no-one else can see it. The VPN server acts as a gateway to the internet, and all your internet data is routed through it.

Once you’re connected to the VPN you are “inside the tunnel,” and it becomes very difficult for anyone else to spy on your web-browsing activity. The only people who will know what you’re up to are you, the VPN provider (usually an HTTPS connection can mitigate this), and the website you’re visiting. This means every time you send and receive data while using a VPN, you don’t need to worry about hackers or snoops intercepting your communications or violating your privacy.

Why do I need a VPN?

Although the answer to this question could be remarkably complex, the main reasons why one needs a VPN are security and privacy. You should strongly consider using a VPN if:

You use public Wi-Fi regularly

When you’re using a public Wi-Fi network, even a password-protected one, a VPN is your best friend. That’s because using public hotspots can be rife with hazards. From man-in-the-middle attacks to Wi-Fi sniffing, there are many different hacking methods that snoopers use to intercept your Internet traffic and steal your social media or banking passwords, files and photos.

The good news is that a VPN allows you to check your email and social media accounts, make banking transactions and shop without the worry of falling into the nightmare of data loss or identity theft.

You travel a lot

If you’re traveling to a foreign country, a VPN can help you access services that may not be available in that country – say, China, where the government blocks sites like Facebook. Even if you just cross a border into a neighboring country, you will most likely lose access to some streaming content to which you subscribe.

Not being able to enjoy something you’ve paid for is frustrating, and here’s where a VPN can help. It changes your IP address, making it look as if you’re browsing from a different location. In fact, if you connect to a VPN server in your home country, you will be able to access all your favorite content securely.

You want to shield your browsing from third parties

Even when browsing online in the comfort of your own home, using a VPN is a pretty good idea. For instance, you may want to buy your little nephew a birthday gift online without being bombarded with toy truck ads for next six months. Or perhaps you need to do a quick research of health clinics without attracting your employer’s attention. If you live in the US, you may simply want to know that your ISP will not be able to sell your entire browsing history to the highest bidder.

A VPN encrypts your Internet traffic and replaces your IP address, making it extremely hard to link it to you. It keeps you from leaving footprints on the web that can otherwise be tracked by your ISP and other third-party snoopers.

You want to avoid government surveillance

Then there’s the widespread surveillance by local and foreign governments. Through the Snowden leaks and years of follow-up reporting, we know that the worldwide surveillance structure is vast in scope and reach. While it would be illegal for police officers to search your home without a warrant, your browsing activity, messages, social media content, and other online information can be monitored, retained and shared among various government agencies, including across country borders.

Using a reliable no-logs VPN service provides a high degree of privacy, protecting you not only from ISP tracking but also from blanket government surveillance.

You use file-sharing services

P2P (Peer-to-Peer) is one of the most effective methods to quickly share large sets of data across a network; it is excellent for distributing open-source software, corporate and scientific data, or public domain videos.

But despite these perfectly legitimate uses, many Internet Service Providers (ISPs) often try to discourage Internet users from P2P file sharing. They do it by controlling access to file-sharing websites or setting bandwidth limits that significantly slow down Internet connection speeds.

A VPN makes it much more difficult for your ISP to detect that you are sharing files and shape your Internet connection accordingly. It ciphers your file downloads, uploads, and actual IP address so that you become unidentifiable.

How to get and use a VPN?

In spite of the fact that more and more Internet users join the VPN trend, many people still believe that using a VPN service is somewhat close to rocket science. While it’s true that some digital security tools can be confusing, best VPN service providers design their apps to be intuitive and easy-to-use.
