Central Processing Unit (CPU): The Control unit, Memory unit and Arithmetic Logical Unit (ALU) are together known as CPU. CPU is the brain of amcomputer system.The data is processed in the CPU. CPU performs the following tasks:
Control Unit: The control unit controls all the units of the computer . It controls the flow of data and instructions to and from the storage unit to the Arithmetic and Logic Unit (ALU). All devices or parts of the computers are interacting through this unit only. Thus, it is also known as the central nervous system of the computer. Arithmetic Logic Unit (ALU): The ALU can do basic arithmetic operations such as addition, subtraction, division, multiplication and logical operations (such as and, or, not, equal to, greater than and less than, etc). The control unit sends the data from the storage unit to ALU, whenever computations are needed. When the operations are completed, the result is transferred back to the storage unit. The ALU is divided into the Arithmetic Unit (AU) and the Logic Unit (LU). AU Performs the arithmetic operations, and LU performs the logical operations. Memory unit: All input data, instructions and temporary data to the processes are stored in the memory. Memory is generally classified into two types –
Primary memory: The computer memories which are directly accessed by the processor using the data bus are called primary memory. Primary memory resides within the CPU. It permits a processor to access stored running programs and currently processed data stored in a memory location. Examples:
Secondary memory: Secondary memory is the storage device that is used to store data the permanently. It is also known as removable storage media. Examples:
Secondary memory is a non-volatile memory (data with or without electrical power). It is slower and cheaper than primary memory. Important! Note: Input provided to the computer is called as data, and the output generated after processing the input, based on the instructions specified by the users, is called as information. Raw facts and figures which can be processed using arithmetic and logical operations to obtain information are called data.

The ALU is fed instructions by the control unit, which acts as a traffic cop, sending instructions to the ALU.
Which part of the CPU solve the arithmetic logic statement?The arithmetic/logic unit (ALU) contains the electronic circuitry that executes all arithmetic and logical operations.
Which part of the computer is used for arithmetic operations?Abbreviation of arithmetic logic unit, the part of a computer that performs all arithmetic computations, such as addition and multiplication, and all comparison operations. The ALU is one component of the CPU(central processing unit).
Who performs CPU logical operations?There are 2 parts of the CPU:
