    The length of the TCP header is specified here. This helps the receiving end to identify where the header ends and the data starts from.

    📝 Note The header length is represented by 4 bits, i.e., the numbers

    0000

    →

    1111

    0000→1111

    or

    0

    →

    15

    0→15

    in decimal which is not enough to represent the potential 60 bytes of the header. Hence, this number is multiplied by 4 upon receiving. So

    1111

    1111

    would represent

    60

    60

    . In other words, the way the 4-bit header length field is used to represent a maximum header length of 60, is that this field represents the number of 4-byte words in the header
