 Source Port is a 16-bit source port number.
 Destination Port is a 16-bit destination port number.
 Sequence Number is a 32-bit sequence number.
 Acknowledgment Number is a 32-bit number that identifies the next sequence number that the receiver is expecting
to receive.
 Data Offset is a 4-bit number that indicates the total number of bytes in the TCP header (option included) divided by 4.
 A flag bit is 6-bit. URG: the urgent pointer field is significant; ACK: the acknowledgment field is significant; PSH:
indicates the push function; RST: resets TCP connection; SYN: synchronizes the sequence number (establishing a
TCP connection); FIN: no more data from the sender (closing a TCP connection).
