It depends on when it was. Back in 1999 it fit pretty well. Even if not perfect it still was a good teaching tool to explain "how it all works" on some level. Then you got to know the hairy details.
Nowadays "Internet" is mostly HTTP 2 for most people and then this model doesn't even remotely explain the structure of it.
- Rapzid 3y agoIt's not really meant to explain http2? But it still very much applies to how an http2 user gets data from a server..
- robertgraham 3y agoThe book has an extensive section on history. I claim that by 1981, the OSI Model was already obsolete and that it didn't fit well, that was not a good teaching tool, that it has done more to beffudle than enlighten students. The problem being is that if you learned according to the modle, you are not aware of what you misundertood.
- IshKebab 3y agoIt didn't fit any better in 1999 than it does now and it wasn't a good teaching tool because it didn't match reality at all but was presented as if it did. Definitely caused more confusion than learning.
- jdougan 3y agoWhen I was first exposed to the OSI model in the late 80s, it wasn't very good then either.
