Which basic operation process of the central processing unit's control unit is responsible for carrying out commands?

• A. Fetch
• B. Decode
• C. Execute
• D. Store

Answer: (C)

The operation process of the central processing unit's control unit responsible for carrying out commands is the execution phase. During the execute phase, the CPU performs the necessary calculations, data transfers, or logic operations specified by the instruction that has been decoded. It takes the decoded instruction and performs the actions required, which could involve arithmetic calculations, moving data from one location to another, or controlling other parts of the computer system. This phase is crucial because it is where the actual work of the CPU is performed based on the preceding fetch and decode operations. Fetch and decode prepare the instructions, but it is the execute phase that brings those instructions to life by implementing them. Therefore, understanding this process is essential for comprehending how CPUs function and process instructions to carry out tasks within a computer system.
