Which CPU component is responsible for logic operations such as comparisons?

The Arithmetic Logic Unit (ALU) is the component of the CPU responsible for performing logic operations and arithmetic calculations. This includes fundamental operations such as addition, subtraction, and logical comparisons like AND, OR, NOT, and so on. When it comes to comparisons—such as determining if one number is greater than, less than, or equal to another—the ALU processes these logical operations, enabling the CPU to make decisions based on the outcomes of these comparisons.

The other components in a CPU have distinct roles: the control unit orchestrates the operations of the CPU by directing data flow between components and executing instructions; registers are small storage locations that hold data temporarily for quick access; and the program counter keeps track of the address of the next instruction to be executed. While all these components work together seamlessly, the ALU is specifically designated for conducting logical and arithmetic operations.
