What is the purpose of additional hardware like a register between memory and CPU?

• A. To increase processing speed
• B. To perform error checking
• C. To reduce electrical load
• D. To enhance graphics performance

Answer: (C)

The inclusion of additional hardware such as a register between memory and the CPU primarily serves the purpose of increasing processing speed. Registers are small storage locations within the CPU that hold temporary data and instructions that are currently being processed. By having this additional layer of memory very close to the CPU, data can be accessed and manipulated much faster than if the CPU had to retrieve everything from the main memory (RAM) each time. This direct access to fast storage helps improve the overall performance of the system as the CPU can often work with this data much more efficiently. In contrast to the main memory, which has higher latency, registers have extremely low latency, enabling faster data retrieval and processing. In terms of electrical load, while registers do have a lower electrical load compared to larger memory banks, the primary purpose is to facilitate speed in data processing. Enhancing graphics performance is related to dedicated graphics hardware, rather than the function of registers. Error checking is typically handled by other components or processes in the system, such as parity bits or error-correcting code (ECC) memory, rather than by registers. Therefore, while various components in a computer system play roles in efficiency and error handling, the specific function of registers is to increase processing speed by providing quick access to data
