If the CPU reads instructions but produces incorrect arithmetic results, which subunit is most likely faulty?

Answer and explanation

Correct answer: Arithmetic and Logic Unit

The governing concept is the division of CPU functions into specialized subunits. The Arithmetic and Logic Unit, or ALU, performs addition, subtraction, comparisons, and other logical or arithmetic operations. If instructions are being read but the numerical results are wrong, the ALU is the most likely subunit involved. The control unit directs operations, while the power supply and network card do not calculate values.
