will not run on another. On the other hand, there are many different
models of processors within a single family. Each manufacturer
produces processors of ever-growing performance and complexity,
but the different models remain compatible at the ISA level. Popular
families, such as IA32, have processors supplied by multiple
manufacturers. Thus, the ISA provides a conceptual layer of
abstraction between compiler writers, who need only know what
instructions are permitted and how they are encoded, and processor
designers, who must build machines that execute those instructions.

4. Are different processor models compatible at the ISA level?
