What are registers used for in the CPU?

• A. Storing permanent software applications
• B. Temporarily storing data or instructions being processed
• C. Maintaining system configuration settings
• D. Facilitating internet connectivity

Answer: (B)

Registers play a crucial role in the operations of the CPU by temporarily storing data or instructions that the CPU is currently processing. They are small, fast storage locations directly within the CPU that hold immediate data needed for ongoing computations or controls. Since accessing data from registers is significantly quicker than retrieving it from main memory (RAM), these temporary storage areas enable faster processing speeds and efficient execution of instructions. Registers are designed to handle specific tasks, such as holding operands for arithmetic operations, storing the addresses of instructions to be executed next, and keeping track of essential flags that indicate the status of the operations. Their primary function is to facilitate the immediate processing capabilities of the CPU, ensuring smooth and fast execution of programs.
