A. the control unit and the arithmetic logic unit

B. the hard drive and RAM

C. the cache and the motherboard

D. RAM and ROM

Answer: A. the control unit and the arithmetic logic unit

When a CPU (Central Processing Unit) executes instructions to convert input into output, it does so with the help of two essential components: the control unit, the arithmetic logic unit (ALU).

The command unit or the control unit takes care of the process of fetching the instructions from memory, then decoding the instructions and finally coordinating other components of the microprocessor by directing them to execute what has been encoded. It comprises the control hub, which controls the instructions and data traffic directions within the CPU.

However, ALU is the one, which carries out various specified logical operations and actual computations as instructed by the instructions. It performs arithmetic operations as addition, subtraction, multiplication and division common to most microprocessor architectures. The logical operations comprise, among others, comparisons and bitwise operations. The ALU handles these operations upon data delivered by the control unit by saving resulting in either registers or memory.

Definitely, this is the cooperation between the control unit and the ALU. Those bring about instructions and data processing allowing the CPU to perform its fundamental functions and convert input into its necessitated outputs.
