I guess between C and assembly there’s abstract syntax trees and maybe LLVM, which is probably also written in C. Idk I skipped compilers in college.
I also know the networking stack has a bunch of layers, but that felt like its own separate thing to “computers”. I think UDP makes more errors than TCP but UDP also go brrrrr
Hehe, llvm is a compiler framework, basically provides all the utilities for processing an AST.
ASTs have various flavors but they're all the same thing an intermediate representation for a program that optimizers and linkers use to create binaries.
The network stacks meh, 6 or 7 layers depending on what protocol you use but in brief: physical, transport, application. More and more functionality has moved into the transport in the name of efficiency, see quic. But in general not worth worrying about most of the abstraction was nonsense anyways.
And you missed out compilers was one of the most useful classes in cs circulums since it teaches you how languages work.
I KNOW! My biggest mistake in college was worrying about my GPA and that worry keeping me from taking harder classes. But I did learn about ASTs.
