How a VPN actually works| know the unknown | science behind it

hello everyone and welcome back to our

Channel

today we are going to talk about one of

the most popular technologies that we

all use but might not fully understand

vpns or virtual private networks

in this video we'll take a closer look

at what vpns are how they work and why

you might want to use one

part one what is a VPN

a VPN is a technology that allows you to

create a secure and encrypted connection

to the internet

essentially it's like creating a private

Network within a public network

[Music]

when you use a VPN your data is routed

through a server that encrypts your

connection and hides your IP address

part 2 how does a VPN work

to understand how a VPN Works let's

consider the example of Alice and Bob

and response to access a website but she

doesn't want anyone to know what she's

doing online

[Music]

Bob runs a VPN service and analyst

decides to use it

when Alice connects to the VPN her data

is encrypted and sent to go off server

from there the server decrypts the data

and sends it onto the website Alice

wants to access

the website responds to the server which

encrypts the data and sends it back to

Alice

the key takeaway here is that Alice's

connection to the internet is now

encrypted and hidden from anyone who

might be watching

it's important to note that vpns don't

actually make you anonymous online but

they do make it much harder for anyone

to track your online activities

part 3 why user VPN

there are many reasons why you might

want to use a VPN

for example if you are traveling and

using public Wi-Fi you might want to use

a VPN to protect your personal

information from hackers

similarly if you are accessing

geo-restricted content a VPN can help

you get around those restrictions

another reason to use a VPN is to

protect your privacy from your internet

service provider ISP

in some countries this is a required by

not to keep loss of their users online

activities

by using a VPN you can prevent your ISP

from seeing what you are doing online

part 4 how to choose a VPN

[Music]

if you're considering using a VPN there

are a few things you should keep in mind

when choosing the provider

first and foremost you want to choose a

provider that doesn't keep loss of your

online activities

this ensures that even if someone were

to demand access to your provider

servers they wouldn't be able to find

out what you've been doing online

you'll also want to consider the speed

and location of your provider servers

if you are accessing content from

another country you'll want to make sure

your provider has servers in that

country to ensure a fast and reliable

connection

part 5 conclusion in conclusion vpns are

a powerful tool for protecting your

online privacy and security

mind flipping your connection to the

internet and hiding your IP address a

VPN makes it much harder for anyone to

track your online activities

if you're considering using a VPN be

sure to do your research and choose a

provider that meets your needs
