Port Number is a 16-bit integer that is used by software and operating system to send and receive data.

The range of port numbers is from 0 to 65,535 where 0 to 1043 are well-known ports, 1024-49151 are registered port numbers, and 49152-65535 are dynamic port numbers that can be used by users to create their own self-networks.
