VPN(Virtual Private Network) Explained:-What is VPN?How does it work?


We are always trying to keep our data private & safe for which we use many techniques like using an incognito mode that we discussed in the last article. In this article let's understand a VPN as a way to keep your data private and safe.

What is a VPN?

VPN or Virtual Private Network is a technology that creates a safe and encrypted connection over a less secure network, such as the internet.VPNs are used by remote workers who need access to corporate resources, consumers who may want to download files and business travelers who may want to log into sites that are geographically restricted. 

How Does a VPN Work?

Imagine that you live on an island in a huge ocean. There are thousands of other islands all around you, some very close and others farther away. The common means of travel between islands is via ferry. Traveling on the ferry means that you have almost no privacy: Other people can see everything you do.

Let's say that each island represents a private local area network (LAN) and the ocean is the Internet. Traveling by ferry is like connecting to a Web server or other device through the Internet. You have no control over the wires and routers that make up the Internet, just like you have no control over the other people on the ferry. This leaves you susceptible to security issues.
So how does a VPN fit in? Using our analogy, suppose each inhabitant on your island has a small submarine. Let's assume that each submarine has these amazing properties:
·        It's fast.
·        It's easy to take with you wherever you go.
·        It's able to completely hide you from any other boats or submarines.
·        It's dependable.
·        It costs little to add additional submarines to your fleet once you've purchased the first one.
Although they're traveling in the ocean along with other traffic, the people could travel between islands whenever they wanted to with privacy and security. That's essentially how a VPN works.

Why You Should Use a VPN?

In Addition to providing a secure way to communicate on the Internet, a VPN has other benefits as well. A VPN can hide a user's browsing activity which is useful when using public WiFi at Airports or other places.VPN also allows users to connect to a site that may be geographically blocked.VPN helps you keep your data safe as well. So it is necessary in this new world to use a VPN.
