Question

A device receives a Transmission Control Protocol (TCP) packet. The device understands where the actual data payload begins. Which portion of the TCP header provides this information?

1) Data offset

2) Acknowledgement number

3) Checksum

4) Sequence num

Answer 1

The answer is 1. Data offset

Step-by-step explanation:

From the Question given, a device that receives a Transmission Control Protocol packet and also understands where the actual data payload begins is called the Data Offset

Data offset: This is the 4 bit data offset field, also referred to as the header length. It indicates the length of the TCP header so that we know where the actual data starts from or begins.
