very simple, for the sake of simplification:
- each computer in your network is identified by its own IP (assigned by router)
- each computer has "ports" that lets outside connections interact with ...
Thanks for the explanation
One more thing I don;t get...it seems that these IP (even with ports) are very similar between each other
e.g. your example 192.168.0.3
I am sure a lot of people are using that (coz its between 1-255 right?)
So if you type in 192.168.0.3:21
Wouldn't there be a million people using this as their ftp IP/port?
