>>22409The actual topics to cover will largely depend on what you want to get out of it. Since you mentioned ASCII, I assume you are interested in the actual representations used by computers and not just the numeral systems in mathematics. I'm sure there are plenty of textbooks that cover these things but I can't recommend any because I learned these stuff by attending lectures in university.
I would cover at least these topics:
- Boolean algebra, maybe a little digital circuits
- Numeral systems (binary, octal, decimal, hexadecimal)
- Bitwise operations
- Number representations (BCD, sign-magnitude, one's complement, two's complement, floating point)
- Memory, endianness
- Arbitrary precision numbers (maybe?)
- Character encodings (ASCII, ISO/IEC 8859, Unicode)
- Maybe some simple image format like something from netpbm? Or some other example of how other things are represented in computers. 3D models, audio? idk
I'm sure I missed something, hopefully other anons will insult me for it,
