हार्डवेयर क्या है और इनके नाम

do you know that what is hardware, Computer hardware can be divided into two main categories: the central processing unit (CPU) and everything else. CPU is the brain of the computer and performs all computing tasks. Other components, such as input and output devices, are not as important as they are simply devices that help input data and create outputs.

The Central Processing Unit (CPU) is an important piece of hardware in any computer system as it performs all computing tasks. It can be thought of like the human brain, which controls everything we do through our bodies, but it does so much more quickly because of its ability to perform millions of calculations per second.

Without hardware, we can never even think about the image of a computer. Let us now know in detail what is computer hardware,

What is Computer Hardware – What is Hardware in Hindi

Computer hardware is a collection of physical devices used to process and store information in a computer system, such as central processing units (CPUs), memory, input devices, output devices.

Computer Hardware

The definition of computer hardware is the physical components used to process and store data in a computer system. These components include the central processing unit (CPU), memory, input devices, and output devices.

There is a complete example of this, the screen that you are reading my article on the screen right now can be any of the screen Computer, Tablet, Mobile. All the input, output, processing and storage devices in a computer are all hardware.

Without any hardware, your computer does not exist, and without it you cannot use any software. If SW is the soul of the computer then your body is the hardware of the computer. But in reality, in order to get any work done from the hardware, we Software make use of.

What is the definition of hardware?

The term computer hardware refers to the physical components of a computer system. These are things you can touch and see.

The term computer hardware is often used interchangeably with computer parts, but they are not the same thing. Computer parts refer to the individual pieces that make up a complete system. For example, the CPU is part of a computer but is not considered hardware because it cannot be touched or seen like other components.

Types of Hardware – Types of Hardware in Hindi

A computer system is made up of hardware and software. Hardware refers to the physical objects that are used to make a computer system work. Hardware includes devices such as keyboard, monitor, mouse and printer, which are connected to the computer.

Hardware can be classified into three categories:

1) memory device: These are devices that store data in electronic form. Memory devices include hard disks and flash drives.

2) input device: These are devices that allow users to input data into a computer system. Input devices include keyboards, mice, and joysticks.

3) output device: These are devices that allow users to output data from a computer system. Output devices include monitors, printers and

computer hardware names

Here are some hardware examples to give you.

1. Keyboard

Keyboard is an input device. Without this hardware, some data cannot be entered in the computer. With the help of this, we can do all the writing tasks of the computer. What you are reading now is also written with this keyboard. You can also see and touch this electronics devices. It is one of the most used devices. There are other hardware components inside as well. This device is installed in the USB port.

2. Mouse

It is also known as pointing device and cursor moving device. One Mouse Can have 2 or 3 buttons. Such as the right, left, and middle buttons (Left key, Right key, Middle key Roller). These are all hardware. The mouse is placed on the flat surface or on the mouse pad. It is used to control the cursor.

3. Scanner

It is the external hardware of a computer. Using a scanner, written papers and photographs can be converted into digital images and stored in memory. Documents can also be scanned and stored in the computer through the scanner. This is called Extenal H/W.

4. Monitor

computer monitor It is an electronic device which is used to show output in some computer. It looks just like a TV. A bigger and better display resolution shows us a better picture. This hardware is of small size in LAPTOP and slightly larger in Desktop.

CRT Monitor: These are heavy and large and use up a lot of deskspace and electricity. This is the oldest used technology. It is based on cathode ray tube technology which was made for television. But these monitors do not work nowadays.

LCD Monitor: One way is the flat panel display. This is a newer technology than CRT. These monitors use less desk space. It is of less weight. These monitors use less electricity. For a long time, these monitors are being used on laptops and notebook computers, they also work as touchscreens on tablet computers, mobile phones.

5. Speaker

This is also external hardware. Using this we can hear sound. It gives output in the form of sound. Nowadays it remains inbuilt in the system.

6. Printer

Printer is an output device that prints the information received from the computer on paper, this copy of the output on the paper is called hard copy. That’s why the need was felt that the information can be stored in the printer itself, so the printer also has a memory from where it prints the results slowly.

7. Motherboard

Motherboard It is the main part of the computer. You need to open Computer to see it. This is a board called PCB (Printed Circuit Board). This board holds the different components of the computer. And all those components are CPU, RAM, Hard Disk, smps port, Graphics card,

8. CPU (Microprocessor)

CPU Whose full name is Central Processing Unit. It is not a hardware itself, there are many small and big hardware inside it. It is also called the brain of the computer. It controls the computer. We do what our mind tells us to do. Mainly its 3 components are ALU, CU and MU. ALU which is called Arithmatic and Logical Unit. CU Control Unit and MU Memory Unit. ALU arithmetic calculations like Addition, Subtraction, Multiplication and Division. LU performs comparison operation. Like less than, greater than, equal to and not equal to. MU has primary and secondary memory.

9. RAM

RAM Full name of Random Access Memory. It is also called Direct Access Memory, this memory is usually of less size than the Secondary Memory in the computer. Like in your mobile it is up to 1GB, 2GB, 3GB, 4GB. This is an electromagnetic disk. This hardware is in Rectangle shape.

10. Expansion cards

Graphics Cards – It looks like a hardware card, it is inserted in the MOTHERBOARD. Graphics card is used to do Image Rendering / Producing on the monitor. Converts the data in such a way and generates signals which is easily understood by your monitor.

The better the graphics card, the better the image is produced. It is necessary to have a Graphics Card for Gamer’s and Video Editor dear people. It is installed in the motherboard. Its shape is like a chip.

sound card Its other name is audio output device, sound board, or audio card. The sound card is an expansion card and IC. Helps to remove noise. Which we can hear through speakers and headphones.

11. SMPS

SMPS The full name of hardware is Switch Mode Power Supply. This is an electronic circuit. If you buy separately for Desktop, then you will get some square shape box, the same is SMPS. This device gives power to different parts of the computer such as RAM, motherboard, gives power supply to the fan. By the way, electricity goes from the motherboard to different parts.

12. Hard Disk Drive (HDD)

HDD It is a data storage hardware device. Lives inside the computer or laptop. How many files or data or computer programs are stored inside it. The OS is also stored in this HDD. This memory is also known as C drive. After partition, C, D, E drives are also created. Hard drives retrieve data from hard disks, fixed drives, fixed disks, and fixed disOptical drives and store the data in optical discs such as CDs, DVDs, and BDs (Blue-ray discs). Their storage capacity is very high.


DVD Drive is installed in the CPU of every desktop and laptop. Which are also called optical drives. Some other names of DVD drive are Disc Drive, Odd, CD Drive, DVD Drive. They are used to store digital data. It is used to play the DATA which is present in DVD, CD in computer.

difference between hardware and software

  • Hardware and software are dependent on each other in Apsa. Both (Software and Hardware) work together to give proper output.
  • It is impossible to use sw without hardware support and thus it is impossible to use sw without hardware.
  • Using hardware without set of programs is negligible
  • To do any work in the computer, it is very necessary to first load the software into the hardware.
  • Hardware needs to be purchased only once.
  • It costs a lot to build and maintain the software.
  • To perform different types of jobs from the same hardware, many different software is installed. (One monitor can do many tasks like Movie, Word, Paint, editing on H/W but we need to install different S/W)
  • sw acts as an interface between h/w and the user.

So there was only one principle to say that both are nothing without each other. The hardware required in a computer is as much as the S/W requirement.

future of hardware

When the first computer was made, all its components were in different rooms and they were connected through cables. After this, the size of the computers that were made was further reduced, due to which the size of the hardware also became smaller. These hardwares were further reduced with the help of VLSI (Very Large Scale Integration) and LSI (Large Scale Integration) technology. Now due to technology, the size of the computer has become equal to a clock. With the help of ULSI, Nano technology, microprocessor, now even the smallest size hardware is being made.

What did you learn today?

It is always my endeavor that you get correct and precise and complete information. you probably learned all this today What is Hardware, Frankly, we are surrounded by hardware. Because they have made our life easy and simple. Have you ever thought how will your mobile and computer be? The answer is that it will happen or else you will think. We can feel the computer touch but never the software.

Day by day software is taking more memory and the size of the hardware is getting smaller. This is the hope from you, maybe you must have liked this article, how did you feel, you must tell below. If you want to ask any question now, then definitely write in the comment box below.
