TCP/IP Protocal Stack

What is encapsulation?TCP/IP Protocal Stack?

Each layer adds a header and a trailer send to the another layer.
Trailer is Error checking methods

One person Writing data in his own PC.
He likes to send file to destination , In Between how it works

Here We going to explain How TCP/IP Works

What actually happens IF the files passes through TCP/IP .

TCP/ IP Protocal consist of
-Applicaion
-Transport layer
-Internet
-Network access layer.

Step 1
Application Layer(DATA)-->Assume that you have Big DATa . One DATA you can't send in one single shot.
What it will do ,

Here Application Part over

Step 2

Transport Layer --->It will segerate as a segment after that sequene wise one by one will send.

Segment - Segregated
Sequence-> First , Second , Third
Port number - This Data should go through this ID

Here Tansport part over

Step 3

Internet Layer

All There things merge in Transport Header--->Begining of the information

Assume segement , sequence and port num in the courier cover .
Sequence --->In that courier cover we need address, that mean Sequence need to know source and destination IP
also we required Who sends it ---> Source IP Address
Who received it --> Destination IP Address

Here we knows how to that get to that district->Network , How do that get to that building -->IP address---> Here involves Router

Step 4

Network access layer -MAC Address

Here you are sending to the building suppose you need to send to the particular person mean,
you required Source and Destination MAC Address--Here involves switch.

Trailer is the end of the information

In that courier has 100 pages, whether same pages destination person received or not , Here error checksome is coming to the picture.

Courier everythig filled up , now going to post in postel box . Small truck will come and take it up --->Here Framerelay involves
Framerelay knows where the data should go.

Step 5
Phsical Layer

Here Truck should go in road right ? That's what Ethernet cable involves here
Also we can send courier to Aeroplane too , that's what Fibre cable involves here
