1) If i am not mistaken, high-order bits are used to begin commands, tho the low-order bits are still used in these commands...

But the thing i dont understand is this....i am told that low-order bits are used to store data, can anyone explain exactly how this works or if i am mistaken, try to explain how it works, i am a little lost.

2) What is the difference between the CPU "codebook" and the CPU instruction set?
 
The order depends on whether the system is big / little endian im sure, but usually the operator comes before the operands in a machine instruction. =)

Im not sure what you mean by code book, but the instruction set are all the instructions recognized by the cpu.

Hope that helps some, be more descriptive with your question.
