What is ALU in computer definition?
Definition of arithmetic logic unit computing. : a circuit in a computer’s central processing unit that performs basic mathematical calculations … the core of a central processing chip is the arithmetic logic unit or units. These units do basic operations like addition, multiplication and division. —
What is arithmetic logic shift unit?
Arithmetic Logic Shift Unit (ALSU) is a member of the Arithmetic Logic Unit (ALU) in a computer system. It is a digital circuit that performs logical, arithmetic, and shift operations.
How many transistors are in a ALU?

What is arithmetic and logical unit?
In computing, an arithmetic logic unit ( ALU ) is a digital circuit that performs arithmetic and logical operations. The ALU is a basic building block of the central processing unit (CPU) of a computer, even the simplest microcontrollers contain one for purposes such as timing.
What is the function of the ALU?
The purpose of the ALU is to perform mathematical operations such as addition, subtraction, multiplication and division. Additionally, the ALU processes basic logical operations like AND/OR calculations. Also known as the arithmetic logic unit, it serves as the computational hub of the Central Processing Unit (CPU) for a computer system.
What is a logic unit?
A logical unit number (LUN) is a unique identifier for designating an individual or collection of physical or virtual storage devices that execute input/output (I/O) commands with a host computer, as defined by the Small System Computer Interface (SCSI) standard.
What is computer arithmetic?
Computer arithmetic is a branch ofcomputer engineering that deals with methods of representing integers and real values (e.g., fixed- and floating-point numbers) in digital systems and efficient algorithms for manipulating such numbers by means of hardware circuits or software routines.
