Data transfer in TCP

I am a beginer on studying the TCP/IP, and I would like to ask, how does TCP send out packets after data arrive from the application layer?
 
Ah, the question doesn't make a lot of sense. My suggestion would be to start at the beginning. I highly recommended a book by the title of "TCP/IP Illustrated Volume 1" by Richard W. Stevens. You can find it on Amazon or your book supplier of choice.

This book is the easiest to understand that I know. The author wrote (he died a year or so ago) in a very easy manner that doesn't put you to sleep, well not as easily as some authors can. :) This is a fairly dry topic so don't expect a gripping thriller either.

If you still have questions after reading this, write back again with your now more refined question.
 
The physical layer passes it up to the Data-link layer 2 where the bits are "framed". Then it goes up to the network layer 3 and packaged into "packets". That is when you see in IP packet. From there it goes to the Transmission layer 4 where the packet is encapsulated with a TCP,UDP etc.

Basically, you need to read heaps.

Good Luck

Bealy
