2.Are all registores inside CPU is volatile? Any non volatile registers inside CPU?

Answer 1

Answer:

Within the actual processor, register is a memory location that works in a very high speed. It stores the instructions which will be executed.

It is usually seen inside the CPU and it maintain the data that the CPU is processing,  where as the memory holds the data that are required for to start the processing therefore there are no registers inside the primary memory.

No the registers inside the CPU are not volatile. Because they store or hold the data that the CPU is processing,

Yes there exists non volatile registers inside CPU.
