Registers in a CPU are used for:a. Long-term data storageb. Temporary data storage and data manipulationc. Arithmetic operations onlyd. Data input only

Break Down the Problem

1. Identify the purpose of registers in a CPU.
2. Analyze each of the given options (a, b, c, d) related to the function of registers.

Relevant Concepts

• Registers in a CPU are small storage locations that hold data temporarily for immediate processing. They are fundamental for operations that require fast access to data.

Analysis and Detail

1. Option a: Long-term data storage - This is incorrect as registers are not designed for long-term storage; instead, they are volatile and lose their content when power is off.

2. Option b: Temporary data storage and data manipulation - This is correct. Registers are used to store data temporarily during processing and assist in data manipulation, such as performing arithmetic and logical operations.

3. Option c: Arithmetic operations only - This is misleading. While registers can be involved in arithmetic operations, their purpose is broader. They also store data for other types of processing.

4. Option d: Data input only - This is incorrect because registers do much more than just handle data input; they also participate in processing that data.

Verify and Summarize

Based on the analysis, the most accurate option regarding the function of registers in a CPU is option (b) - they serve as temporary data storage for data manipulation.

Final Answer

b. Temporary data storage and data manipulation
