The arithmetic logic unit is a digital circuit that is part of the CPU. Its main functions are to do arithmetic and logic operations.
The arithmetic and logic unit (ALU) within the computer's central processing unit (CPU) carries out arithmetic operations. Some designs also support a dedicated floating-point processing unit (FPU), which carries out arithmetic, trigonometric and logic operations based on floating-point variable types.

Control Unit
The Arithmetic and Logarithmic Unit of the CPU.
Central Processing Unit(CPU)
The unit that performs the arithmetic and logical operations within the processor is called the Arithmetic Logic Unit (ALU).

ALU
Comparisons and calculations are performed in a logical block called ALU - the Arithmetic-Logical Unit. This component (be it really a component or a set of components performing the function) is tasked with mathematical operations of any order above 1s and 0s, and - of course - with logic (binary logic, to be exact).
No, the Instruction Decoder and Sequencer part of the Control unit directs and coordinates all of the operations of a computer; including the ALU, I/O, Load/Store, etc. units.
Processor - Aka Chip or Microprocessor
ALUShort for Arithmetic Logic Unit, ALU is one of the many components within a computer processor. The ALU performs mathematical, logical, and decision operations in a computer and is the final processing performed by the processor. After the information has been processed by the ALU, it is sent to the computer memory.In some computer processors, the ALU is divided into two distinct parts, the AU and the LU. The AU performs the arithmetic operations and the LU performs the logical operations.

Because addition and subtraction are the basic arithmetic operators, which all other arithmetic operations are based on. Multiplication can be posed as repetitive addition. Raising to a power is repetitive multiplication, etc. The processor of a computer basically is just a really fast adder.
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.
processor
CPU expands to Central Processing Unit. CPU as a Unit refers to main components interconnected within a Box called Cabinet. Cabinet houses components such as Power Supply, Motherboard, Processor, RAMs, Harddisk Drive & other components as per requirements.Inside CPU on Motherboard with a special designed socket the BRAIN of the Computer lies called Processor/MicroProcessor. The Processor is designed that is fabricated as a single unit comprises of Control Unit & Arithmetic/Logic Unit (ALU).Control Unit executes all Instructions related part whereas ALU performs all Mathematical & Logical Operations.
