The brain of any computer is its CPU. However, the brain of any CPU is the ALU.
ALU short for Arithmetic And Logical Unit is the component that resides inside the CPU which processes data according to the given instructions && commands.
it is used to calculate arithmetic and logical operation
ALU stands for ARITHEMATIC LOGIC UNIT .It is a combinational circuit for arithematic and logical bitwise computation.

Business data processing and Scientific data processing.
The example of electronic data processing is the use of the computer in processing data.
Processing occurs after data have been entered into the computer.
Data is processed to get the required results. Different operations may be performed on data. Therefore, data processing is defined as:"A sequence of operations on data to convert it into useful information is called data processing."The important operations that can be performed on data are:Arithmetic and logical operations on data to get required results.To send and receive data from one location to another.Classification of data.Arranging data into a specific order etc.The data processing is divided into three categories or levels.1. Manual Data Processing: In manual data processing, data is processed manually without using any machine or tool to get required result. In manual data processing, all the calculations and logical operations are manually performed on the data. Similarly, data is manually transferred from one place to another. This method of data processing is very slow and errors may occur in the output.In Pakistan, data is still processed manually in many small business firms as well as government offices & institutions.2. Mechanical Data Processing: In mechanical data processing, data is processed by using different tools like calculators or other mechanical devices. This method of data processing is faster and more accurate than manual data processing.3. Electronic Data Processing: It is the modern technique to process data. The data is processed through computer. Data and set of instructions are given to the computer as input and the computer automatically processes the data according to the given set of instructions.The computer is also known as electronic data processing machine. This method of processing data is very fast and accurate. Now-a-days, the data is processed and analyzed through computers. For example, the results of students are prepared through computer; in banks accounts of customers are processed through computers etc.
Registers
The CPU is in charge of processing the data. In more detail, the ALU (Arithmetic Logic Unit) is in charge of executing logical and arithmetic operations. The ALU is a component of the CPU.
Major operations are three operations: Compiling and processing data done by CPU Graphic Generation and processing done by GPU Arithematic and logic Processing Done by ALU
ALU ( Arithmetic Logic Unit )
ALU-Arithmetic logic unit,cpu-central processing unit
The ALU (Arithmetic-Logic Unit) is generally a subsection of the CPU (Central Processing Unit). While the CPU is the master driver of a computer, the ALU is a processing area optimized to handle mathematical computations and logic comparisons. The processor controller passes operation codes and operands to the ALU, which performs the requested operation on the supplied data and passes back the results.
8 bit ALU and most of data processing registers will be 8 bit
The Arithmetic Logic Unit (ALU) inside the Central Processing Unit (CPU) of the computer.Most modern computers however do not have a single general purpose ALU that handles everything, but instead have several independently functioning special purpose ALUs optimized for specific data types (e.g. integer numbers: I-ALU, floating point numbers: FP-ALU, boolean logical values: LU).
The ALU (arithmetic logic unit) An ALU loads data from input registres, an external Control Unit then tells the ALU what operation to perform on that data, and then the ALU stores its result into an output register. Other mechanisms move data between these registers and memory.
ALU- Arithmetic Logic Unit CU- Control Unit alu performs the arithmetic and logic operations. cu is the one which controls the entire processing.
