Hello people this is Shark the author today we will learn about computer networks and there's my assistant Nemo who's gonna assist us
Nemo
Hello everyone~~
Mr Shark
So first thing we will learn about computers is how they communicate
Nemo
Liked wired and wireless?
Mr Shark
Yes nemo but there's a protocol that every computer follows while communication. Wired and wireless are subjects where we will discuss later-
Nemo
Oh i know the protocol you're talking about its osi model right ?
Mr Shark
Yes Nemo its the very same osi model but for those who don't know osi model is a 7 layer protocol which is the main backbone of communication between different computers
Mr Shark
tell me the name of the 7 layers nemo
Nemo
The osi model has 7 layers namely
Application layer
Presentation layer
Session layer
Transport layer
Network layer
Data link layer
Physical layer
Mr Shark
Very good that's absolutely correct and while communicating the computers follow from the app layer down to the physical layer from where the data travels in raw bits to the physical layer of other computer and from that physical layer it goes upto application layer for us to look at
Nemo
But Uncle Shark does this happen all the time ? Like every second ?
Mr Shark
Yes Nemo it happens with every single packet sent on the network this is how networks work as we know the data is sent into the forms of small packets each packet follows this protocol until it reaches the destination.
Mr Shark
Okay guys now we have to end this chapter we'll meet again in the next one
