We all love the Internet, On an average
We use internet for almost 9 hours
We watch videos
Chat with friends, and post on Instagram
And we search things on google, and what not?
But, How does internet actually work?
We send data from one place and it is delivered to another place, how?
Well we are going to find this out.
What Internet actually does?
It helps to communicate between two or more devices
Until they are connected through any medium
That medium can be
your wifi or mobile data
And this communication is possible
with the help Servers
Servers, are directly connected to the central wire of the Internet
Any websites you visit on Internet
Or anything you post on Facebook
Everything is stored in the servers
Devices like
Mobile, Laptop, PC, Tablet are not drectlty connected to the Internet
We are connected through an ISP's or Internet Service Providers
Internet Service Providers. This can be your Ncell Network, Worldlink Broadband
or any of the home fibres.
As we are connected though your ISP's
and search anything on Internet, we send request to the server
we send request to the server
and the server responds our request and sends the requested file back to the client
In this transaction, Client is our devices
But, whatever I send to my friend through the Internet
Why it does not get transferred to his neighbour? but goes to him only
but goes to him only. Well here
router plays an important role. Router makes sure that
your data is transferred to its destination securely
All our homes have their own postal address likewise
every devices which is connected to the internet have their own
unique address called IP Address
or Internet Protocol Address
Ip Address are the list of random numbers
which is very difficult to memorise, that's why
we give then names like google.com,
facebook.com
These name are called DNS
or Domain Name Servers
 
Let's take a look how it works. While you were scrolling your phone
you loved one meme and you decide to
send that meme to your friend. You send that
meme using your wifi. Your router
changes that meme into 0s and 1s
and send request to your ISP. Then your ISP
finds your friends home router and
send the request. And that router again changes 0s and 1s
back to the meme
and finds the correct
device and sends that meme to your friends device
and that's how your friend gets the meme
