In a microprocessor, what is the meaning of the term 'ALU'?

Explanation:
The ALU is the part of the microprocessor that carries out arithmetic and logic operations. It handles tasks such as addition, subtraction, multiplication, division, and bitwise operations (AND, OR, NOT, XOR), along with shifts and comparisons. The control unit directs the ALU to perform a specific operation on operands taken from registers, and the result is sent back to a register or memory. The acronym stands for Arithmetical Logic Unit (often shortened to Arithmetic Logic Unit). The other phrases don’t refer to a standard CPU component, so they don’t describe what the ALU does.
