Question: We need to multiply the header length field by _______ to find the total number of bytes in the TCP header.
Answer:
In TCP, the header length field is a 4-bit field that specifies the length of the TCP header in 32-bit words. To find the total number of bytes in the TCP header, you need to multiply this value by 4.
Therefore, the formula to find the total number of bytes in the TCP header is:
Total TCP header length = Header Length field x 4 bytes per word
Since the Header Length field can have values from 5 to 15 (corresponding to TCP headers of length 20 to 60 bytes, respectively), the total TCP header length can vary from 20 to 60 bytes.
