Instruction set:
	The set of things the CPU can do
	It'll have actual transistors for these things
	Anything else has to be simulated in software

Note about that:
	"Software modem"
	Logical equivalency
		If you can do it in software, you can do it in hardware
		You do need some kind of hardware, but it can be minimal
	RISC vs. CISC
		Reduced vs. Complex
		This isn't a binary distinction
			Example:  Acorn Risc Machines

Memory and bandwidth
