I’ve read and seen videos on the OSI model and from what I remember it’s just a reference model for how you should develop a network in a computer but it’s not strict in that you should follow it exactly how it looks?
I could be misremembering but if I’m not then my question is why do we use it in the first place? Is it just a checklist of sorts to make sure we’re including the main parts?
Also as a follow up question, in networking I always see ports as in port (long number) I am always confused are these actual physical ports?

The OSI Model classifies network traffic into “layers”. Each layer interacts with specific protocols. This is why a few years back you’d hear folks talking about a “layer 7 firewall” and such…. hope this helps start your down the path of knowledge!
