Two main categories of Processors registers are:
1)User-visible resisters:-programmer can assign these registers to some variables while writing the program codes.
2)Control and status registers:-These registers are not user-visible.But cpu uses these registers to control the execution of programs or to store information about the interrupted program so that processor can resume the program after execution of interrupt.
