Which unit can store instructions, data, and intermediate results
Correct answer: C. Storage Unit
- A. Arithmetic Logic Unit (ALU)
- B. Control Unit
- C. Storage Unit
- D. All of the above
Explanation
The storage unit, also known as main memory or primary memory, is the component that stores instructions, data, and intermediate results that the CPU needs to access. It is typically volatile memory, meaning that data is lost when the computer is turned off. However, there are also non-volatile storage devices like hard disk drives and solid-state drives that can store data permanently. In conclusion, while the ALU and control unit play essential roles in processing data, it is the storage unit that serves as the repository for instructions, data, and intermediate results within a computer system.
