Answer / pinar uyanik
Port addresses are smaller than IP addresses because their
domain is smaller.
Port addresses does not necessarly need to be unique. But
port addresses together with the IP address uniquely
identifies the particular server program on a particular
host.

Answer / madhu
Port Adresses need to be unique for some well known
applications.
Ex: NTp Server , TFTP Server,FTP Server etc
Totally the port numbers range from 0 to 65535 . In that 0
to 1024 are used for well known or particular applications
(Servers)These ports are called ephemeral ports. The rest
can be used for normal usage.
The port address field in the header of TCP as well as UDP
protocol is of 16 bits length where as the IP address filed
of the IP Header is of 32 bit length. So the port addresses
can range from 0 to 65535 (2^32-1) only.
