Ex. When 2 host access google.com then the IP address of host are 192.168.1.1 port no is 80 also 192.168.1.2 p.no 80 when the router receive packet from google.com.
It will change port number for ex. Public IP is 21.10.1.1 P.81 for 192.168.1.1 P.No 80 and 21.10.1.1 P.No 82 for 192.168.1.2 P.No 80. In router there will be change in port addr of host that is called PAT.

PAT (Port Address Translation) includes ports in addition to IP addresses.
Many-to-one translation. Maps multiple IP addresses to 1 or a few IP addresses. Unique source port number identifies each session. Conserves registered IP addresses.
Also called NAPT (Network Address Port Translation) in IETF (Internet Engineering Task Force) documents.

Port has address based on physical media. It is 100% correct.

Hey Nandi, for static NAT- We are giving the manual ip to every host in the network which will be converted into public ip address by NAT.
for Dynamic NAT - We are providing the pool or set of public IP addresses to all hosts instead of giving it manually to every host.

NAT: NAT means Network Address Translation. Or PAT: It means Port Address Translation. And both are consist of similar to each other only difference is that NAT is One IP one port and PAT is One ip multiple port.
