alu is for the logical and arithmetical operations in the system unit.
In computing, an arithmetic logic unit (ALU) is a digital circuit that performs arithmetic and logical operations. The ALU is a fundamental building block of the central processing unit of a computer, and even the simplest microprocessors contain one for purposes such as maintaining timers. The processors found inside modern CPUs and graphics processing units (GPUs) accommodate very powerful and very complex ALUs; a single component may contain a number of ALUs.

The function of the Arithmetic Logic Unit is to perform the arithmetic operations and boolean logic operations needed during instruction execution.Some Arithmetic Logic Units also provide temporary storage for operands and/or results of these operations in registers or accumulators, others do not provide any temporary storage (depending on the computer's architecture and/or implementation).
The Arithmetic Logic Unit as suggested by the name carries out the arithmetic calculations of the computer.
The arithmetic logic unit or ALU performs arithmetic, logic, and integer operations. ALU was created by mathematician John von Neumann in 1945.
There is a special part of the CPU that performs Arithmetic and Logical calculations. Its called Arithmetic Logic Unit ( ALU ).
The ALU performs arithmetic and logic operations. ALU stands for Arithmetic Logic Unit.
The "arithmetic logic unit" performs these operations in classical standard microprocessor architectures
The arithmetic logic unit is a digital circuit that is part of the CPU. Its main functions are to do arithmetic and logic operations.

Arithmetic Logic Unit - the place where all operations happen in a computer.Other units are:Memory - data and instructions kept here.Control - coordinates all units according to instructions.Input/Output - moves data and instructions in and out of the computer.
