Do you know what is Computer Hardware If you have come to search for these questions, then you are at the right place. You must know that computer mainly consists of two parts: Software and Second Hardware. Software also called Computer Program. Software that you use every day in your mobile and computer. Software's EX-VLC, Chrome, Internet Explorer, MS-WORD, MS-POWERPOINT, Photoshop, pdf reader and Operating System (Android, Windows, MAC, UNIX).
When the first computer was built, all the Components were in different rooms and were connected by cables. After that the computers which were made were reduced to size, due to which the size of the HW also became smaller.
Have you ever thought, all these "Software is nothing of hardware". Think about how you would write in the MS-WORD without a keyboard. Without the mouse, you can not even edit in Photoshop. If you do not store pdf book in hard disk, then read from Adobe Reader. So maybe you understand my things a little bit. Keyboard, Mouse, hard disk, Monitor, Motherboard, CPU, UPS, Speaker These are all a hardware.
1)What is computer hardware
Hardware also speak HW or H / W. HW is the part of computer that we can see and touch. If we describe it in a strict manner, then it is the Physical Component of the Computer, and this Component has circuit boards, ICs, and other electronics. This is a complete example of what you are reading on Screen, which can be read by anyone in Screen Computer, Tablet, Mobile. All the inputs, outputs, processing and storage devices in a computer are all one HW.
Without any hardware, your computer does not exist, and without it you can use any software. If SW is the soul of computer, then your body is the computer's hardware. But in reality, we use software to do anything from hardware. If you want to listen to the song in the computer, then you will not say that you will speak to the computer and the song will play. Whenever Paly will do the song in Windows Media Player or VLC (both of which are softwares) then that song will play on the Speaker. Meaning hw is controlled through sw.
2)Types of Hardware
You must have seen two types of system: 1. Laptop 2. Desktop All the physical components of the Laptop are connected. But the components of the desktop come apart. But hw is almost the same in both. Let us know about the types of hardware and Examples.
Keyboard
This is an input device. Without this hardware, you can not even enter some data in the computer. With the help of this, we can do all the works of computer writing. What you are reading now is written by the same keyboard. You can also view and hide this electronics devices. This is one of the most used devices. There are also other HW components inside it. This device is installed in the USB port.
Mouse
It is also known as pointing device and Cursor Moving Device. A mouse can have 2 or 3 buttons. Just like right, left, and middle button (Left key, Right key, Middle key roller). All of these are a HW. It is used to control Cursor.
Monitor
Monitor is an electronic device that is used to show output in some computers. It looks like a T.V exactly. A big and great display resolution shows us a good picture. This hardware is of a small size in the LAPTOP and is slightly larger in the desktop.
Scanner
This is a computer's external HW. Using scanner, written papers and photos can be converted into digital pictures and kept in memory. Documents can also be stored in a computer by scanners. This is called Extenal H / W.
CRT Monitor
They are bulky and big and use deskspace and electricity. This is the oldest technology used. It is based on cathode ray tube technology, which was created for television. But these monitors do not run today.
LCD Monitor
A method is a flat panel display. This is new technology than CRT. These monitors make use of less desk space. It consists of low weight. This monitors use less power. For the same time, the same monitors are being used on laptops and notebook computers, these touchscreens also work on tablet computers, mobile phones.
Printer
External HW Printer is an output device that prints the information obtained from the computer on the paper. This copy of the output on paper is called a hard copy. The output of the information gets very fast from the computer and the printer can not work so fast. Therefore, it was felt that information can be stored in printers, so there is also a memory in the printer from which it prints the results gradually.
Speaker
This is also External Hardware. By using it we can hear the sound. It gives output as sound. Today, it remains inbuilt in the system today.
Motherboard
This is the main part of the computer. You need to open the computer to see it. This is a board called PCB (Printed Circuit Board). This board captures different Computer Components. And all those Components are CPU, RAM, Hard Disk, Smps port, Graphics card.
CPU (Microprocessor)
The CPU is the full name of Central Processing Unit. It is not a hardware itself, it has many small hardware inside it. It is also called a computer's brain. It controls the computer. Just as our brain tells us what we do. Mainly its 3 Components are ALU, CU and MU. ALU called Arithmatic and Logical Unit. CU Control Unit and MU Memory Unit. ALU arithmetic calculation such as Addition, Subtraction, Multiplication and Division. LU Comparison Operation Performs. Like Less than, greater than, equal to and not equal to MUs have primary and secondary memory.
RAM
The full name of the RAM is Random Access Memory. It is also called Direct Access Memory, this memory is much less than the Secondary Memory in Computer. As in your mobile it is 1GB, 2GB, 3GB, 4GB,8GB,16GB. This is the Electromagnetic Disk. This hw is in Rectangle shape.
Expansion cards
1) Graphic cards
It looks like a HW card, it is inserted into the MOTHERBOARD. Graphics card is used to monitor image rendering / production. Convert Data to something like this and Generates Signals which your Monitor easily understands. The more graphic cards, the better the image produce is. Gamer's and Video Editor Dear people, it's important to have a graphics card. It is fitted in the motherboard. Its size is like a chip.
2)Sound cards
The second name is audio output device, sound board, or audio card. Sound card is an expansion card and IC. Helps in removing the shout. Which we can hear through speakers and headphones.
SMPS
The full name of SMPS hardware is Switch Mode Power Supply. This is an Electronic Circuit. If you buy separately for the desktop, then you will get some square shapes that are SMPS. It gives power to different parts of the Device Computer, such as RAM, Motherboard, Fan, to power supply. By the way, there is electricity from different parts of Motherboard.
Hard disk drive (HDD)
HDD This is a Data Storage Hardware Device. Lives inside the Computer or Laptop. As many files or data or computer program is stored inside it. The OS is also stored in this HDD. This memory is also known as C drive. After partition, C, D, E Drive are also formulated. By retrieving data from hard drive, hard disk, fixed drive, fixed disk, and fixed disOptical drives and store data in optical discs like CDs, DVDs, and BDs (Blue-Ray discs). Their storage capacity is very high.
DVD DRIVE
DVD Drive is installed in the CPU of every Desktop and Laptop. Also called Optical Drive. Some other names of the DVD drive are: Disc drive, Odd, CD Drive, DVD Drive They are used to store digital data. The DATA that is recorded in the DVD, is used to play it in the computer.
