Easier way is to remember that the ISO model is defunked and you should use the TCP/IP model.
we’re getting back there, for example HTTP/3 separates session from transport, and web browsers separate presentation from application
Yes, except if you are in my University, where professors are fossils and knowing OSI is required to pass the CN exam.
TCP/IP model is Limited and incomplete.
Fibrechannel, infiniband, and many RDMA protocols, just to make a few, don’t fit in the TCP/IP model, while the OSI model fits them just fine.
How don’t they fit?
Neither TCP, UDP, nor IP, is involved.
But they don’t run CLNS so the ISO model doesn’t fit either.
OSI model != OSI protocols
CLNS is not a pre-requisite for Layer 3.
Accurate
Application: full of itself; just look at it; leaking out of its constraints.
Presentation: not happy; has to talk to the app.
Session: chillin; don’t start nothin, won’t be nothin.
Transport: ready for whatever comes its way.
Network: acting up as usual.
Data Link: Hidden but watching, well-behaved, compliant.
Physical: draping out of the rackInternet is cats, all the way down.
Please Do Not Throw Sausage Pizza Away !
Ah yes, the EtherCAT.
All People Seem To Need Data Processing
But Few Purchase Software (Bits, Frames, Packets, Segments)
People Don’t Need Their Stupid Packets Anyway
Layer 8…
I have only ever know two devs that knew what the fuck OSI was. two out of at least one-hundred and fifty.
it’s nice to see a technical joke on here that’s more than just “hehe your language is bad”.
I think “technical” is a bit of a stretch… But who doesn’t like a good cat meme?
Missing the latest addition to the OSI model: AI!
Layer 8 (sender): turning a few keywords into a well-formed text
Layer 8 (receiver): summarising text back into its short form
Believe it or not this made it harder
thank god I dropped out before going into the real nerd stuff
It’s missing layer 8 with a cat slowly and intentionally pushing the stack over while looking the IT cat directly in the eyes as it finally topples over. Then complains that nothing’s working but also not providing any helpful information.
Ohhhhhhhhh!
