port numbers

[Ammybashide]

what is the port no of 

1) Network time protocol(NTP)

2) transmission control protocol(TCP)

3) user datagram protocol(UDP)

4) Internet protocol(IP)

5) Address resolution protocol(ARP)

6) Reverse Address resolution protocol(RARP)

[Marvin Rhoads]

Port numbers are used by transport layer protocols such as TCP and UDP. Those both run on top of IP.

I would suggest your class materials would be a good place to read as well.
