What is Hardware- Definition, Types, Examples

Do you know what is Hardware and how many different types there are? If you’re into computers, you’ve probably come across the terms hardware and software.

Because these are the two most important components of a computer, it would be impossible to function without them. He has the appearance of a human without a body or a mentality.

This is because if you understand how these sections of the computer work, you will be able to readily address the computer’s basic problems.

Have you ever considered that all of this “software is nothing without hardware” Consider how you would write in MS-WORD without a keyboard.

Without a mouse, I can’t even edit in Photoshop. How will you read the pdf book from Adobe Reader if you don’t save it anyplace on your hard drive?

So maybe you get the gist of what I’m saying. The keyboard, mouse, hard disk, monitor, motherboard, CPU, UPS, and speaker are all part of the same hardware package.

We could never even consider the image of a computer without hardware. Let’s take a closer look at what is hardware.

What is Hardware?

Definition -: Hardware is the visible and touchable portion of a computer. It is the physical component of the computer, and this component consists of circuit boards, ICs, and other electronics, if we explain it correctly.

The computer creates a word called hardware by combining all of these devices. That is, the gadgets that make up a computer, and you can see all of their peripherals, are referred to as computer hardware.

Your computer would be useless if it didn’t have any hardware, and you couldn’t use any software without it. If the software is the computer’s soul, then your body is the computer’s hardware. In actuality, we employ software to complete any work that is performed on the hardware.

Types of Hardware

You already know that computer hardware refers to the actual components that comprise a computer. We’ve provided you with numerous examples of this above.

You must have seen that there are numerous during the example, which is why they are grouped into distinct groups. Computer hardware has been divided into four categories below to make it easier for you to grasp.

Input Device

Input devices are hardware devices that serve the purpose of providing input (data) to computers. By employing these, a user communicates with the computer and has his task completed by it.

Overall, they allow you to operate and communicate with the computer. The most basic example is your keyboard, which allows you to enter alphanumeric data and commands into your computer.

Consider whether you could have used the computer if the keyboard had not been included. Many pieces of computer hardware fall under the category of Input Devices.

Examples Of Input Devices

  • Keyboard
  • Mouse
  • Scanner
  • Touchscreen

Some Input Devices Types

  • Pointing Devices
  • Game Controller
  • Audio Input Device
  • Bluetooth Peripheral
  • Visual and Imaging Device
  • Network Device
Pointing Devices

Pointing Input Devices are pieces of computer hardware that allow us to collect input from the user by clicking or pointing to a specific location on the computer’s monitor.

Devices such as a mouse, touchpad, touchscreen, multi-touch screen, pen input, motion sensor, graphics tablet, interactive smartboard, and fingerprint scanner are included.

Game Controller

Game Controller Input Device refers to the hardware that we utilize to control the game while we’re playing it.

It has gadgets such as a joystick, gamepad, and steering wheel.

Audio Input Device

Audio Input Devices are physical devices that we employ to take audio input from the user.

It contains devices such as a microphone and a midi keyboard.

Bluetooth Devices

All hardware devices that connect to the computer over Bluetooth and take input fall under this category.

Bluetooth mouse, Bluetooth keyboard, Wireless LED monitor, Wireless Printer, Wireless Scanner, Bluetooth Speakers, and so on are examples of Bluetooth devices.

Visual and Imaging Device

Webcam, digital camera, digital camcorder, TV capture card, biometric scanner, and barcode reader are among the hardware devices included.

Network Device

A network device is a node in a wireless mesh network. It can send and receive wireless HART data as well as conduct basic network construction and maintenance activities.

Devices such as Ethernet hardware and Bluetooth / wireless gear fall under this category.

Processing devices

When you submit data to a computer using a keyboard or another input device, it goes through an intermediate stage before being delivered to an output device. This is the step at which raw data becomes information.

The processing device refers to the hardware components of the computer that manage this intermediate state. These are also referred to as internal memory devices.

Examples Of Processing devices

  • Central processing unit (CPU)
  • Graphics processing unit (GPU)
  • Motherboard.
  • Network card.
  • Sound card.
  • Video card.

Output Devices

The devices that display the processed data in a human-readable manner are known as output devices; that is, we receive the result of the work that you want to conduct with the help of devices.

The output device is known as. Output devices are pieces of computer gear that provide or optimize computer data to users. For example, a computer screen is referred to as a monitor. The computer’s principal output device is the monitor.

This will be used to contact you with any information. That is, whatever instructions you send to the computer, you can see its result through them. Computers, users, and other gear can only communicate via output devices.

Examples Of Output devices

  • Monitor
  • Projector
  • Video Card
  • GPS
  • Printer

Two Parts Of Output Devices

  1. Softcopy output device
  2. Hardcopy output device
1. Softcopy output device

A soft copy output device is one that allows us to see and read the received output but not touches it.

Devices such as monitors, projection displays, speakers, headphones, and earphones fall under this category.

2. Hardcopy output device

A hardcopy output device allows us to interact with the output.

Dot-matrix printers, 3D printers, Inkjet printers, Laserjet printers, and Thermal printers are all examples of output devices that fall under this category.

Storage devices

This is where computer hardware comes in, which is utilized to store the user’s input data as well as the processing output data.

DRAM, SRAM, ROM, Hard Disk, SSD, optical disks, flash disks, and external disk drives are examples of storage devices.

Two Types Of Storage Devices

  1. Primary Storage Device 
  2. Secondary Storage Device
1. Primary Storage Device 

These storage devices are used to temporarily store data. It’s a modest piece of equipment. As a result, it is contained within the computer.

The data access speed of the primary storage device is the fastest. RAM, ROM, and Cache Memory are examples of these.

1. Secondary Storage Device 

These memory devices have a lot of storage. It also keeps the data for a long time. It can be found both inside and outside the computer.

Hard Disk Drive (HDD), Solid State Drive (SSD), Optical Disk Drive (ODD), Flash Memory, and USB Device are the most common examples.

What is the Future Of Hardware?

When the first computer was built, all of its components were housed in separate rooms and connected via cables. Following this, the size of the computers produced was lowered even further, resulting in a reduction in the amount of HW.

This hardware was further decreased with the help of VLSI (Very Large Scale Integration) and LSI (Large Scale Integration) technologies. Technology has now reduced the size of a computer to that of a clock. Even the tiniest size HW can now be created thanks to ULSI, Nanotechnology, and microprocessors.

Computer System Varieties


The computer casing houses the majority of the system’s components. Internal elements like the motherboard, disc drives, and power supplies are mechanically supported and protected, and the flow of cooling air over internal components is controlled and directed. The enclosure also functions as part of the system to manage electromagnetic interference emitted by the computer and to safeguard internal components from electrostatic discharge. Large tower cases, which normally stand on the floor, provide capacity for several disc drives or other devices, whereas desktop cases have limited expansion area.

Power supply

A power supply unit (PSU) transforms alternating current (AC) electricity into low-voltage direct current (DC) electricity for the computer. Laptops can be powered by a built-in rechargeable battery. A switched-mode power supply (SMPS) is commonly employed in the PSU, with power MOSFETs (power metal-oxide-semiconductor field-effect transistors) used in the SMPS’s converters and regulator circuits.
