    TCP/UDP activities

    Once application layer send the data through layer 7/6/5 to layer 4, does the layer 4 stop that process and send some short of their own bits of data to another side of host for acknowledgement TCP connection, to make sure the it has connection and able to send the data came from above layer .... or the TCP layer, send the first segment of data comes from application layer to another host for acknowledgment to establish the connection to send the another segment of data.

    Re: TCP/UDP activities

    I tihnk Data waits untill TCP connection is established.  3-way handshake.

    then tcp features such as Flow control (windowing) and error recovery (using sequence numbers) are part of tcp headers with Data from above layers. So, once connection is established, session layer Data is placed into a Layer 4 segment.

    Most books show additonal headers appended to prevoius data in OSI model.
