Question

**is a high-speed device used in CPU that is utilised to store data temporarily during processing.**

1. Arithmetic and Logic Unit (ALU)
2. Auxiliary Memory
3. Control Unit
4. Registers

Accepted Answer

**Solution:**

1. The **Arithmetic and Logic Unit (ALU)** performs arithmetic and logical operations but does not store data temporarily.

2. **Auxiliary Memory** refers to external or secondary storage devices like hard drives, which are slower and not used for temporary data storage during processing.

3. The **Control Unit** manages the execution of instructions but does not store data temporarily.

4. **Registers** are small, high-speed storage locations within the CPU used to temporarily hold data and instructions during processing. They are the fastest form of memory and essential for efficient CPU operation.

**Answer:** Registers
