Port numbers identify a particular application or service on a system. An IP address identifies a machine in an IP network and determines the destination of a data packet, while port numbers identify particular applications or services on a system.

What is the difference between physical port and logical port?

after identifying the network physical address is used to identify the host on that network. The port address is used to identify the particular application running on the destination machine. Logical Address: An IP address of the system is called logical address.

Is port 80 and 8080 the same?

Port 80 is the default port. It’s what gets used when no port is specified. 8080 is Tomcat’s default port so as not to interfere with any other web server that may be running.
