Can anyone show me the right pointer for this basic query? I need to know when i type http:\\www.google.com, How the request from my client appn { Browser } reaches to the destination web server.. ? I would like to know what happens in Each & individual layer of TCP ? For example, In HOst to host layer, destination port and dest address is found and added with the TCP header .. Like this can anyone pass me the whole info?

Regards

Saravanan:

Here is a nice write up on TCP/IP:

If you want some light reading, here is a book to buy:

absolute best way to understand TCP, try to speak it.

http://www.ethereal.com is a good tool to start with. this will allow you to see the TCPIP stack and see what happens when you query a server.

i would start on a quiet network and only do one thing at a time so you can see what happens when you press go.

also, remember PDNTSPA, the Open Systems Interconnect (OSI) layer mantra.

Physical = Wireless
Datalink = 802.11b/g MAC
Network = IP
Transport = IP and TCP (tcp/ip was developed before OSI, so this layer is split)
Session = TCP
Presentation = HTTP://
Application = Mozilla
