Aritmeetikaloogikaüksus, often abbreviated as ALU, is a fundamental digital circuit within a computer's central processing unit (CPU). Its primary role is to perform arithmetic and logical operations on binary numbers. Arithmetic operations include addition, subtraction, multiplication, and division, while logical operations encompass comparisons like AND, OR, NOT, and XOR.

The ALU receives data from registers and instructions from the control unit. It processes this data according to the given instruction and then outputs the result, typically back to a register or memory. The control unit dictates which operation the ALU performs by sending specific control signals. The speed and efficiency of the ALU are crucial for the overall performance of a computer system, as it is responsible for executing the vast majority of computational tasks. Modern ALUs are highly complex, capable of performing a wide range of operations at very high speeds.
