Answer
The Arithmetic Logic Unit (ALU) makes all calculations and comparisons. The ALU performs the arithmetic (+, -, *, /) and logical (AND, OR, NOT, XOR) operations sent from the memory and returns the result to the memory. The result of the logical operations is either true or false and helps the computer in decision-making.
