What are port numbers explain?

Answer 1

A port number is a kind of address within a computer. It helps distinguish different services on a server. Thus, any data that goes to port 80 (TCP) will be processed by the Web server; data for other ports gets sent to other applications.

On the client side, the port number helps separate different "conversations". For example, if I load different Web pages at the same time, in my browser, one might be assigned to port 1024, the next to port 1025, etc. This is the origin port; the destination port is still port 80. But when data comes back from the server, my computer will receive it at port 1024, or port 1025, and thus know to which file the information must be added.
