- Instruction Set Architecture : OS系統與硬體之間的溝通介面
- defines how the CPU is controlled by the software
- Abstract model of computer
- The ISA acts as an interface between the hardware and the software, specifying both what the processor is capable of doing as well as how it gets done.
- A device that executes instructions described by that ISA, such as a central processing unit(CPU), is called an implementation
