Question

A von Neumann architecture, which of the following statements are true: The Control Unit contains a register called the program counter (PC) also known as the Instruction Address Register (IAR) or Instruction Pointer (IP) in Intel x86 and Itanium microprocessors. The program counter (PC) typically indicates the address of the next instruction to be fetched from memory, decoded, and executed. The value stored in the program counter (PC) always increases as a stored program executes. Conditional instruction execution and loops are accomplished by "branch" instructions that modify the value stored in the program counter (PC). I, II, IV II, III, IV I, II, III I, II, III, IV

Explanation / Answer

D ) I , II, III, IV

All are correct.

Control Unit contains Program Counter ,
PC stores the next address of instruction to be executed.
PC values increases by one as we move to next instruiction
