Refer to this article : Service overview and network port requirements for the Windows Server system

and read this: Ports and protocols

The port numbers are divided into three ranges: the Well Known Ports,the Registered Ports, and the Dynamic and/or Private Ports.The range for assigned ports managed by the IANA is 0-1023.
