Bit size tcp header
Transmission Control Protocol accepts data from a data stream, divides it into chunks, and adds a TCP header creating a TCP segment. The TCP segment is then encapsulated into an Internet Protocol (IP) datagram, and exchanged with peers. The term TCP packet appears in both informal and formal usage, whereas in more precise terminology segment refers to the TCP protocol data unit (PDU), datagram to the IP PDU, and fr… WebFeb 5, 2012 · When the URG bit is set the Urgent Pointer is also set (in the TCP header Options field: 16 bit). The URG pointer tell how many bytes of the data is urgent in the segment that has arrived. (Example if the data size is 100 bytes and only first 50 bytes is urgent, the urgent pointer will have a value of 50). Now coming to the PSH bit.
