Definition - What does Arithmetic Logic Unit (ALU) mean? An arithmetic logic unit (ALU) is a major component of the central processing unit of a computer system. It does all processes related to arithmetic and logic operations that need to be done on instruction words. In some microprocessor architectures, the ALU is divided into the arithmetic unit (AU) and the logic unit (LU).
The unit octet was defined to explicitly denote a sequence of 8 bits because of the ambiguity associated at the time with the byte. The usage of the term octad(e) for 8 bits is no longer common today.
