Store data or information temporarily and pass it on as directed by the control unit?

The correct answer is Register because CPU registers are ultra-high-speed internal memory locations that store volatile data during processing.

• Register: This is the correct choice. Located inside the CPU architecture itself, registers provide immediate storage for data values, instruction addresses, or calculation steps currently being processed by the Arithmetic Logic Unit (ALU).


• Incorrect Options:
  
  
  
  • Memory: This is incorrect. While broad memory (like RAM) holds data, it sits outside the CPU core and operates at a slower clock rate than specialized internal registers.
  
  
  • Address / Number: These are incorrect. These represent attributes or values held within memory cells rather than active hardware components.
