How semantic analysis catches the errors that parsers cannot, and how type checking guarantees program safety
Why compilers use intermediate representations and how optimization makes programs faster
How optimized intermediate representations become machine code, and a final look back from automata theory to compiler construction
Core concepts of Von Neumann architecture and how CPU, memory, and buses work together
How the ALU, control unit, and datapath work together to execute instructions
The role of ISAs, CISC vs RISC philosophy, and x86 versus ARM design differences
Instruction pipelining, hazard handling, branch prediction, superscalar and out-of-order execution
Why CPUs distinguish privilege levels, and how x86 protection rings and ARM exception levels protect the system
Why interrupts exist and how IDT, ISR, PIC/APIC work
