Hardware and its Types

Hardwares and its types

This is the 4th Lecture of the course of every beginning level course of #IT and #officeautomation. Today we will discuss about the concept of hardware and its types and their working municiples. Input devices, output devices and storing devices and the modern processing devices.

What are Hardware?

All physical parts, components or devices attached to a computer are called Hardwares. Hardwares a are simply computer devices attached with computer to take input, to process, to store data and to present output in the user acceptable format. Most commonly used examples are Keyboard, Mouse, Monitor, Hard disk and speaker.

Types of Hardware

On the basis of the operations an hardware perform we can divide them into four major types.

  1. Input devices
  2. output devices
  3. processing devices
  4. memory/storage devices

Input Devices

Input devices are used to capture data and instructions from user in user acceptable format and enter into computer. The whole operation is called inputting.

  • Keyboard (onscreen keyboard)
  • Mouse (laser, wifi)
  • Microphone (soft copy)
  • Digital Camera (image) , Camcorder (video)
  • Scanner (soft copy), Barcode scanner, Hand Helded scanner
  • Composite Device (Game Controllers, Joystick, Joy pad)

Output Devices

output devices are used to receive information from computer in computer accept form and convert it into user acceptable format and display or print it. The whole operation is called outputting. There are two main types of Output can be made. Hard-copy and soft-copy.

These examples of output devices also include input/output devices.Printers and visual displays are the most common type of output device for interfacing to people, but voice is becoming increasingly available.

  • Speakers
  • Headphones
  • Screen (Monitor)
  • Printer (impact and non impact)
  • Projector

Memory and Storage devices

Memory and storage are same in meaning but a little difference when we use both in computer literate. The Memory mean small and volatile nature of power of saving of computer. The Storage mean the permanent and non volatile “power of saving” of computer.

  • RAM and Rom
  • Cache memory
  • Registers
  • Hard Disk
  • Optical disk
  • Removable medias (USB Drives)
  • Portable Hard disk

Its me Habib Ullah Qamar working as a Lecturer (Computer Sciences) in Pakistan. I have an MS(M.Phil) degree in computer sciences with specialization in software engineering from Virtual University of Pakistan Lahore. I have an experience of more than 15 years in the filed of Computer Science as a teacher. Blog Writing is my passion. I have many blogs, This one is special made with the aim of providing 100% Free online coaching and training to the students of under-graduate and postgraduate classes. Most of the students enrolled in computer sciences, information technology, software engineering and related disciplines find it difficult to understand core concepts of programming and office automation. They find difficult in understanding and solving their assignments.
