What has port numbers in its header?
both tcp and udp
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).

Why are the source and destination port numbers at the beginning of the TCP header?
That is the way the standard designed the header. They could be placed anywhere as long as everyone understood where in the packet header it was placed.
Why are port numbers included in the tcp header of segments?
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?
What header that has source of 13357 and destination port of 23?
It is a TCP Header
How does a client computer determine what source port number to assign to a UDP header?
The port number is random
Which stp port type can only appear once on a segment and must be present in order for traffic to flow on that segment?
designated port
An Internet server is running both FTP and HTTP services. How does the server know which of these applications should handle an incoming segment?
If I understand the question aright; different port numbers are used to identify different protocols. Port numbers between 1 and 1023 are well-known numbers and standards define which protocol uses which. FTP uses port number 21, HTTP uses port 80.
Can oil fron a valve cover leak drip into the header and blow into the exhaust port and out the header?
Yes it sure can and will if the valve covers are leaking oil and the header gaskets are worn out/ leaking.
What are the two basic port numbers?
ephemeral port numbers and well known port numbers
Port number is 16bits what is the minimum header size of a transport layer?
8
