Correct Answer: Microprocessor is a program-controlled device, which fetches the instructions from memory decodes and executes the instructions Most Micro Processors are single-chip devices
Correct Answer: Flag is called as Low order rigister & Accumulator is called as High order Rigister
Correct Answer: Program counter holds the address of either the first byte of the next instruction to be fetched for execution of the address of the next byte of a multi byte instruction, which has not been completely fetched In both the cases it gets incremented automatically one by one as the instruction bytes get fetched Also Program register keeps the address of the next instruction
