Computer Block Diagram and its Various Components

The computer block can process data, images, sound, and graphics. They can solve very complex problems quickly and efficiently.

As shown in the figure, a computer, regardless of size and shape, performs five basic computer operations or functions .

These are:

    1. Accepts data or instructions
    2. Data storage
    3. Data management in accordance with the needs of the user
    4. In the form of output and
    5. Control all actions on the computer

We discuss each of these computer processes below.


Block Diagram of Computer and Explain its Various Components

1. Input:

It is the process of entering data and programs into a computer system. You should know that a computer is an electronic device, just like any other device that uses raw data as input and does some processing to generate processed data.

Therefore, the input unit brings the data to the computer in an orderly manner for processing.

2. Storage:

The process of permanently storing data and instructions is known as storage. The data must be entered into the system before the actual processing can begin. This is because the CPU processing speed is so fast that data must be provided to the CPU at the same speed.

Therefore, the data is first stored in a storage block for faster access and processing. This memory unit or main storage unit of a computer system is intended to perform the above functions. Provides space to store data and instructions.

The storage device performs the following main functions:

• All data and instructions before and after processing are stored here.

• Intermediate processing results are also stored here.

3. Processing: 

The task of performing operations such as arithmetic and logic operations is called processing.

The central processing unit (CPU) takes data and instructions from the memory unit and performs all kinds of calculations based on the given instructions and the type of data provided. Then it is returned to the volume.

4. Output:

This is the process by which data is produced to provide useful information. Also, the version created by the computer after processing must be stored somewhere on your computer before you read it.

Also, the output is also stored on the computer for further processing.

5. Control:

How to follow the instructions and do the steps above. All operations such as importing, processing and publishing are handled by the administrator. It manages the routines of all the activities on your computer.

Functional Units

To perform the steps in the previous step, the computer divides the task between its different types of task parts. The computer system is divided into three separate parts for its operation. They are

Arithmetic Logical Unit (ALU)

    • Logical Unit:

After the data is entered with the input tool, it is stored in the main memory block. The data and instructions are processed by the logical logic unit. The main functions of the ALU are addition, subtraction, multiplication, division, logic and comparison.

If necessary, the data is transferred from the repository to the ALU. After processing, the output is returned to the storage location for further processing or storage.

    • Control Unit (CU):

The next part of the software is an administrator who acts as an administrator to make sure that things are done correctly. The transition board is responsible for coordinating the various functions by marking the time. The administrator determines the order of operation of the software programs and instructions.

Things like processing programs in main memory, interpreting instructions and sending signals to other computer hardware to work. It also acts as a keyboard trigger when multiple users have access to the computer at the same time. It therefore regulates the performance of computer equipment as they go in and out.

    • Central Processing Unit (CPU):

The ALU and CU computer systems are referred to as the central processing unit. You can call a CPU the brain of a computer system. It is like the brain that makes all the key decisions, performs various calculations and controls different parts of the computer’s functions by activating and controlling the functions.
