Computer Block Diagram System: The computer system consists of three main parts, which are the central processing unit (CPU), Input Devices, and Output Devices. The Central Processing Unit (CPU) is divided into two parts again: the arithmetic logic unit (ALU) and the control unit (CU). The set of instructions is in the form of raw data.
A large amount of data is stored in the computer memory with the help of primary and secondary storage devices. The CPU is like the heart/brain of the computer. The user does not get the desired output, without the necessary option taken by the CPU. The Central processing unit (CPU) is responsible for processing all the instructions the user gives to the computer system.
The data is entered through input devices such as the keyboard, mouse, etc. After receiving input from the user, the CPU processes this set of instructions, and the computer system generates the output. The computer can show the output with the help of output devices to the user, such as a monitor, printer, etc.

CPU (Central Processing Unit)
The computer system is nothing without the Central Processing Unit so, it is also known as the brain or the heart of the computer. The CPU is an electronic hardware device that can perform different types of operations such as arithmetic and logical operation.
CONTROL UNIT (CU)
The Control Unit governs all internal activities within the computer system, receiving instructions directly from the main memory. Upon receiving an instruction set/information, the CU translates it into control signals, which are then transmitted to the central processor for further processing. It ensures the precise execution of operations in the correct sequence.
ARITHMETIC AND LOGICAL UNIT (ALU)
The arithmetic and logical unit is the combinational digital electronic circuit that can perform arithmetic operations on integer binary numbers. It presents the arithmetic and logical operation. The outputs of ALU will change asynchronously in response to the input. The basic arithmetic and bitwise logic functions are supported by ALU.
STORAGE UNIT
The information or set of guidelines is stored in the storage unit of the computer system. The storage unit provides the space to store the data or instruction of processed data. The information or data is saved or held in computer memory or storage device. Data storage is the core function and fundamental of the computer components.
