Hi Sachin,

TCP/IP is a method of addressing places on the internet, while HTTP refers to communication protocols when accessing websites. So an example would be if you wanted to host your own domain, and wanted to provide a website, as well as email and file transfers, your domain would have an IP address, with a TCP protocol to establish communication, and then you would need to set up HTTP for websites, SMTP for email and FTP for file transfers. This allows your server to provide the right information based on the requested communication.

You could think of it in terms of your house. For someone to access your house, they would need your address and directions to get there (analogous to TCP/IP protocol). What they do when they get there is dependent on the context. If you were throwing a party, your guests might take the front door and come right in, where as a caterer might need to go through the back and check in with someone. While they all took the same route to get there, they perform different functions once the destination has been reached.

Hopefully this helps.

Thank you for this explaination. I get it!

I would say imagine that TCP/IP is the post office or FedEx where they are responsible for the breaking down of packets of information and routing them to and from their destinations. The sender and receiver all have an IP addresses which would represent their individual mailing address in the analogy and HTTP would be the initial request to send or receive.
