What is VPN


What is VPN | Have you ever opened a browser and been searching a site, and have you ever encountered the error **You Are Not Authorized To Access This Web Page As Per The Dot Compliance**?  Then remember that the site is blocked by either ISP's or Government. 

If you are in college and if you are using college Wi-Fi then you may notice that some movie download sites like torrentz or social media sites like facebook, instagram or porn sites are closed then those sites are closed by your college staff. You can access those sites by using VPN.

How do we access internet by using your mobile or computer, When you use the internet , you are using the service of any Internet Service Provider like Airtel, Jio, BSNL. When you open the browser in mobile or computer and search google.com then the request first goes to your service provider and from there it goes to google's server and then you can access google.com. But these service provider can block some sites. To access this block sites you can use VPN.

How VPN Works or How To Access Block Sites Using VPN

When you are accessing any block site and you are using a VPN, you are searching any data or service from the any site which means you are requesting that data or service from server. When you are using VPN this request is encrypted and encryption connection is established. ISP can not see that requested data as it is encrypted between your device and VPN server. 

When your computer sends a request to the ISP, The ISP does not know which site you want to go to, ISP only knows that you want to go to that VPN server so it lets you to connect to that server through router without connecting to that block site. VPN server checks that request, opens that packet and he knows that you want to go that block site then connection is established for server to go to that block site. That server can be anywhere in India or even outside India. We can easily access the sites which are blocked by our College, ISP or Government. Your ISP does not know which sites your are accessing but all the information does know ISP's of VPN server so you cannot hide completely.

Does VPN help to increase internet speed?  No. Even though VPN speed is 1 gbps, your computer's speed will be the same as your ISP provide. You connect the VPN with the speed given by your ISP.
