A communication between two devices is over the maximum limit of an ethernet frame size. The Transmission Control Protocol (TCP) splits up the data into segments. Which field in the header helps keep track of the many segments?

A. Urgent pointerB. Acknowledgement numberC. ChecksumD. Sequence number

D. Sequence number

Explanation:

The sequence number facilitates the keeping track of many segments. This enables it to determine which segments out of many in which it should be in. The sequence number field is usually 32 bits.

Sequence numbers are used in transmitting data because of their importance. Since data is transmitted in packets, they can be lost and as such the receiver uses the sequence numbers to reorder them.
