What is Computer Hardware and Software :: Computer Hardware is defined as the physical part or component of computer system which can be feel, seen and touched. Computer monitor which we use to view the display is a Hardware Device, A printer which we use to Produce ouputs,a computer memory which is used to store data or programs all are the types of hardware used in computer system for better functionality of computers.

Computer software can be defined as a set of instructions or collection of programs which are designed and developed to perform specific tasks. IT professionals develop customized programs which can be used in certain areas of our day to day life .These types of software or programs are very helpful and can reduce human efforts immensely.

What is computer hardware and software

  1. 1. Welcome to WHAT IS COMPUTER HARDWARE AND SOFTWARE
  2. 2. Computer Hardware and Software  Computer Hardware is defined as the physical part or component of computer system which can be feel, seen and touched. Computer monitor which we use to view the display is a Hardware Device, A printer which we use to Produce outputs, a computer memory which is used to store data or programs all are the types of hardware used in computer system for better functionality of computers.  Computer software can be defined as a set of instructions or collection of programs which are designed and developed to perform specific tasks. IT professionals develop customized programs which can be used in certain areas of our day to day life .These types of software or programs are very helpful and can reduce human efforts immensely.
  3. 3. PC Software can be categorized  System Software  Application Software A Computer software needs hardware to function properly. For Example A Hard disk drive is a hardware device of a computer system which saves or stores information, programs or data in high volumes but it cannot work in absence of software programs. The software helps hardware to run and vice versa.
  4. 4. System Software  System software is any software which controls the hardware so that any application software can run and can be executed to perform various task mentioned by programmers .  System software runs and executes programs, they also monitor various other component of a computer system like CPU, primary and secondary storages, and other peripheral devices of PC.  They communicate and control peripherals devices like printers,scanners,webcam,sound cards etc.
  5. 5.  They perform transferring of data to hard disk, It performs text or images or graphics to be seen on display devices, There are various other system software which is developed for specific tasks, such as device drivers are installed in PC for better functionality of that device,  For example :: Device drivers of display cards and sound cards are used in viewing better resolutions on computer screen and hearing sound from soundcards.
  6. 6. Application Software  Application Software is program which is designed and developed for specific purposes and for a special task which is directly used by the users.  In other words, it can be described as an interface between user and system software, which helps the user to perform a given specific task.  Common Application software is word processor and spreadsheets.
  7. 7.  Some of the application SW are bind in together with other application software such as MS-OFFICE SUITE comes with MS-Word, Excel, PowerPoint & Access. And Adobe includes Adobe Photoshop and Image ready together.  Pre-Installed Application Software which is installed automatically or in another word we can say that they come as a package includes in Popular Operating system such as MICROSOFT Windows.  For Example :: Paint & Windows Media Player
  8. 8. Types of Hardware Component Used in Computer & Their Differences  As we have discussed above that hardware are physical devices which can be touched.  Different and common types of hardware devices and their uses are mentioned below for better understanding  Cabinet Case  Motherboard  RAM  Hard Disk  CPU  SMPS (Switching Mode Power Supply)  Keyboard  Mouse  Monitors  Printers  Speaker etc
  9. 9. Cabinet Case  Cabinet case comes in various shapes and sizes but commonly used case is a tower case whose height ranges from 15 to 25 inches.  They enables different types of hardware devices to be fit in itself to make it a whole and all the devices are connected to the case using screws.  The Commonly attached hardware devices to PC case are Power supply, Motherboard CPU , Ram , Hard disk , DVD-RW etc.
  10. 10. Motherboard  Motherboard or mainboard is nothing but a piece of PCB (printed circuit board) where all the other devices are connected to it using cables & wires.  Motherboard generally distributes all the voltages and power received from SMPS or power supply to other parts of the hardware devices attached to PC.
  11. 11. RAM  RAM [Random Access Memory] is an essential part of the computer system which is used for storing data or program temporarily.  It is a volatile memory which tends to lose the data when power is missing from a power supply. When RAM is found missing motherboard gives a sound, and no display is found on monitors.
  12. 12. Hard Disk Drive  Computer Hard disk drives are used to store the data permanently. It is a type of non volatile memory which does not loses data or programs when there is no power.  Nowadays huge volume of data can be stored in hard disk . Which are also called as secondary storage hardware devices.  The hard disk capacity is measured in MB- MEGABYTES, GB-GEGABYTES & TB-TERABYTES
  13. 13. CPU [Central Processing Unit]  CPU stands for Central Processing Unit which is responsible for almost all the operation computer system performs .  CPU performs Arithmetical and logical operation which includes addition , subtraction, division and multiplication and logical operations includes comparison, less and greater values.  Every input which is send by input devices is first collected in primary memory and later transferred to CPU for further processing.
  14. 14. Different Types of System Software & Their Uses  Translators  Device Drivers  Utility Programs  Operating System
  15. 15. Translators  These are those programs which translates codes which are written in high level or Assembly language into Machine language or that language which is easily understood by computer.
  16. 16. Device Drivers  These programs are used to help better functionality of hardware devices. Such as mouse, sound cards and keyboards Utility Programs  Format, Defragmentation, cleaning of hard disk space & installing and removing application programs from PC. These utility programs help the user to better communicate and interact with software and hardware.
  17. 17. Operating System  This acts as the primary interface between a user and computer hardware. It Presents user a GUI stands for Graphical User Interface where the user can directly communicate or interact with hardware and software used in computer systems.  The system software manages and controls hardware and user inputs. They are also used in providing an interface for the development of application SW.
