Why are port numbers included in the tcp header of segments?

Updated: 10/3/2023

So the destination host knows what port to send it to. If the destination just takes a guess as to what port to send it to and sends an RDP packet to port 80 what do you think is going to happen?

For transport information, the protocol needs to know what port to deliver the packet to. A port has a listening program on the other end to receive it.

What happen during segmentation in transport layer protocol?

The original data stream is broken into pieces, called "segments"; each segment is numbered (numbering is by bytes, not by segments). Other header information is added too, for example, the origin and destination port numbers.The original data stream is broken into pieces, called "segments"; each segment is numbered (numbering is by bytes, not by segments).

How does the transport layer tell the difference between different data segments?

In order to tell the difference between different data segments the transport layer assigns an identifier to an application. The TCP/IP protocols call this identifier a port number. Each software process that needs to access the network is assigned a port number unique to that host. This port number is used in the transport layer header to indicate to which application that piece of data is associated. Hope this helps!!!
