What is VPN(Virtual Private Network)?

VPN is the computer network that will create a layer on the internet(Overlay).


Why we need VPN?

When we're going to do something personally on the internet everyone can track your activities and IP address at this point VPN is coming to help.


Normal Internet connectivities and accessing:


Normally when we're going to connect the internet to phone or system internet service provider will provide internet facilities. For example, if your going to connecting internet to mobile using sim then sim is internet service provider


Without VPN?

Without connecting VPN two members can track our activities and collect the data also. Can you guess who?

The first one is a hacker and the second one is the government. So at this point, I want to tell one important thing to you i.e without VPN our data will not be encrypted and IP address can easily access(Through IP address only can take whole data) moreover hackers can easily collect and misuse some valuable data also.


With VPN?

With connecting VPN our IP address will not show but will show VPN service provider IP address(Hackers cannot access VPN service provider IP address)and cannot access our IP address, data will be encrypted.

Then which person can have our data's after connecting VPN?

Absolutely VPN service providers. They will have our whole data but its all under government rules. If government need then they will provide our data to the government

Net Speed?

Two things for reducing internet speed compare to the actual speed
  • Distance
  • Based on VPN service providers computers
Distance:

For example, connecting VPN from the US or any other country then imagine the distance.

VPN service providers computers:

If VPN service providers have a supercomputer or quantum computer then we can expect internet speed

Usage of VPN:

  • Date encrypting
  • Hackers cannot follow and take data
  • Our IP address is replaced with VPN service providers IP
  • Secure connection

How to get VPN?

There is much more free VPN available on the internet
