Performing logical and mathematical operations on data is the responsibility of the logical unit in the CPU of a computer.
The logical unit, also known as the arithmetic logic unit (ALU) is the component of the CPU that carries out arithmetic and logical operations on data. This includes basic math functions like addition, subtraction, and comparison, as well as logical operations like AND, OR, NOT, XOR, and bit shifting.
The ALU receives data from registers within the CPU executes the operation, and sends the result back to the registers. So in short, the main responsibility of the logical unit is to perform computations and logical tests on data within the CPU.
