Answer:

Segment

Step-by-step explanation:

Port numbers is a 16-bit number that identifies the application the data is bound for. The Destination and Source port are usually contained in the segment, particularly in the first word of the segment header. Accurate dissemination of data to and from the Application-layer protocols is an integral function of the Transport Layer services.
