Which component handles arithmetic and logical operations within the CPU?

• A. Arithmetic and Logic Unit (ALU)
• B. CPU Core
• C. RAM
• D. ROM

Answer: (A)

Arithmetic and logic operations inside the CPU are handled by the Arithmetic and Logic Unit. The ALU is the part of the processor that actually performs calculations (like addition, subtraction, and multiplications) and logical operations (such as AND, OR, NOT, and comparisons). It takes operands from the CPU’s registers, computes the result, and writes the result back to a register or memory location. It also updates status flags that help the CPU decide subsequent steps in a program. The rest of the CPU, especially the control unit, coordinates which operation to perform, but the actual arithmetic and logic work is done by the ALU. RAM and ROM are memory components, not computing units, and the CPU core refers to the broader processing unit that includes the ALU along with other parts.
