Learning Outcome

TCP/IP

“ Have you ever sent a parcel and sometimes needed confirmation that it reached safely, but other times you just sent something quickly without caring much?”

   Layman Example

Example:
Think of TCP and UDP like two ways of sending parcels:

 You send a package

 Courier confirms pickup

TCP (Safe Delivery Service)

       Tracks it         →        Delivers

 You get confirmation

UDP (Fast Delivery Service)

 You just throw multiple                →             no tracking                  →           no confirmation

  packages quickly  

You write a letter

Put it in an envelope, and add sender and receiver addresses — your message is ready to be sent.

You give it to the post office, which takes responsibility for delivering it.

The post office routes the letter through different sorting centers to reach the correct city.

A postman delivers it to the exact address of your friend.

Your friend receives, opens, and reads the message.

    What is the Use of TCP/IP  Model ?

Enable communication between devices over the internet.

Ensure data reaches the correct destination using

IP.

Provide reliable transfer using TCP or fast transfer using UDP.

Support all internet services. (web, email, apps)

How It Works (Step-by-Step)

• TCP/IP model explains how data moves between devices over the internet in a simple structured way

• Data starts when a user makes a request (like opening a website)

• The request is prepared, organized, and broken into small parts for easy transfer

• Address information is added so data knows where to go

• Data travels across the internet through different paths and networks

• The receiving device collects all parts and joins them back together

• The original information is restored and shown to the user
