Friends, hardware is such a device that helps us in our work. Whether it is any work, we can call all such devices as hardware, which come in our work, which we can touch and see. In the same way, if we talk about the computer sector, then here also all kinds of equipment are used to work on the computer. that we can touch. You can see that computer hardware is there. So in today's post we will try to know what is computer hardware? (What Is Computer Hardware) How many types of computer hardware are there? (Types of Computer Hardware) Definition of Hardware (Hardware Definition in Hindi) as well as will know about the difference between Hardware and software etc.
What Is Computer Hardware What is computer hardware?
There is no significant existence of a computer without hardware. Because a computer is made up of many hardware devices. If we understand hardware in simple words, then all those devices or devices that we can see and touch are all hardware. Or you can say that the physical elements which we can see and touch are all called hardware. In the same way, in the field of computer also all those devices which help in working on the computer. What we can touch and see is called computer hardware.
Definition Of Computer Hardware
Hardware is the physical part of the computer. In which many digital circuits are involved. The hardware of a computer works in conjunction with its software and provides output to the user according to its instructions. Without computer hardware, the existence of computer or computer software is negligible. Talking about the Definition of Computer Hardware, you can understand computer hardware in the following way.
Internal Hardware
External Hardware
Internal Hardware
These are the internal components of the computer which are not usually visible to us from outside. But this hardware converts the input data into information and provides output to the user. Including processing device. As :
CPU
RAM
Motherboard
Graphic card etc.
Keyboard
Monitor
Mouse
Keyboard
Printer
Scanner
Hard Disk
SSD
Speaker its.
Mouse
It is also known as pointing device and cursor moving device. A mouse can have 2 or 3 buttons. Such as the right, left, and middle buttons (Left key, Right key, Middle key Roller). All these are HW each. The mouse is placed on the flat surface or on the mouse pad. It is used to control the cursor.
3. Scanner
This is the external HW 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 is an electronic device which is used to show output in some computers. It looks exactly like a T.V. A big and good display resolution shows us a good picture. This hardware is of small size in LAPTOP and slightly larger in Desktop.
CRT Monitor: - These are heavy and large and use 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: - There is a type of 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
External HW. 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
This hw 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
CPU (Microprocessor)
The full name of CPU 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. e.g. Less than, greater than, equal to and Not equal to. MU has primary and secondary memory.
9. RAM
The full name of RAM is 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. It is in hw Rectangle shape.
10. Expansion cards
Graphics Cards – It looks like HW card, it is inserted in MOTHERBOARD. Graphics card is used to do Image Rendering / Produce 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 important 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. Sound card is an expansion card and IC. Helps to remove sound. Which we can hear through speakers and headphones.
11. SMPS
The full name of SMPS 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 This 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.
13. DVD DRIVE
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.
Hardware and Software are dependent on each other in Apsa. Both (sw and hw) work together to give precise output.
Without HW it is impossible to use sw without support and thus it is impossible to use sw without Hw.
Using hw without set of program is nil
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 software.
To perform different types of jobs from the same hw, many different software are 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. As much as hw is needed in a computer, S/W is also needed.
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 HW also became smaller. With the help of VLSI (Very Large Scale Integration) and LSI (Large Scale Integration) technology, these hardwares were further reduced. 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 HW are 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 (What is Hardware in Hindi). Frankly, we are surrounded by hardware. Because they have made our life easy and simple. Have you ever wondered how your mobile and computer will be like? The answer is that it will happen or else you will think. We can feel the computer touch but never the software.
In today's digital age, almost everyone knows about computers. And, almost everyone knows about the different parts of the computer. Computer has two main parts: 1. Hardware and, 2. Software. Software is a program that is accessed by hardware. That is, the software is controlled by the hardware.
You guys will surely have this much information. But, what complete information you have about the hardware, probably not. So do you know what is hardware? Hardware Types. Difference between hardware and software. What is the role of hardware in computer etc. If not then this post is very useful for all of you.
What is Hardware? Definition
Generally, hardware is the physical part of the computer through which software programs can be accessed. Now if we describe in detail what is hardware, then it is like a type of machine, which is made up of many small and big electronics components. And, this hardware term is not only used in computers. Every single component of the smartphone that you have, ie the machine, is called hardware.
We can also touch the hardware. This hardware is such a part of the computer, apart from which the computer cannot even be thought of, because hardware is the body of the computer and software is its soul.
Types of Hardware
You have got information about what is hardware. Now comes the question regarding the type of hardware. That is, what types of hardware are there. To answer this, let us tell you that there are mainly four types of hardware: 1. Input Device, 2. Processing Device, 3. Storage Device, and 4. Output Device.
There are many devices under these four types, which have different characteristics. We have described in detail below about the types of hardware.
1. Input Device
Input device, Keyboard, Mouse, Speaker, Scanner etc. comes first in all the four types of hardware. As:
1) Keyboard
The most important input device of a computer is the keyboard. It performs the task of transmitting text and facts to the computer and providing instructions through the keyboard. That is, through the keyboard, all the data related to letters (ie A,B,C,D,E etc.) and numbers (ie 1,2,3,4,5 etc.) is input into the computer. We can see different types of keys in the keyboard.
