Question 24

Does an ALU work independently or in coordination with some other unit? Give reasons.

Answer

Arithmetic Logic Unit (ALU) does not work independently; it operates in coordination with the control unit and memory. The control unit fetches instructions from memory and decodes them, directing the ALU to perform specific operations such as addition, subtraction, or logical comparisons. The results produced by the ALU are then stored back in memory or used by other components of the computer system.
