This document provides an overview of basic computer system hardware components including input, processing, storage, and output devices. It describes common input devices like keyboards, scanners, and pointing devices. It explains that the central processing unit (CPU) and microprocessor handle processing. Storage devices covered include hard drives, floppy drives, CD-ROM drives, and removable hard disks. Finally, it outlines standard output devices such as monitors, printers, and speakers.

3. Input Devices An input device lets you communicate with a computer. You can use input devices to enter information and issue commands. Most common input devices are: Keyboard Scanner Digital Camera Pointing Devices

8. >pointing devices move some object on the screen and can do some action Example: P O I N T I N G devices Mouse Trackball Joystick

9. Mouse Trackball Joystick > a pointing device that rolls around on a flat surface and controls the location of the pointer on the screen. > consist of a metal or plastic handle mounted on a base that you can move in any direction to move the pointer or other object. > it is rolling a ball around with your fingers to control the location of the pointer.

16. Storage Hard Drive Floppy Drive CD-ROM Drive Removable Hard Disk

17. >it is the primary device that a computer uses to store information and stores programs, data files, saves files, and organizes files. >it magnetically stores data on stacks of rotating disks called platters. H A R D D R I V E

25. Output Devices Monitor Printer Speaker An output device displays information on a screen, creates printed copies or generates sound. It enable the computer to give or show you the results of its processing. Examples are:

26. >shows the processed information on a screen and used to display video output to a user. >uses a Picture Tube like a television with the image displayed on the front of the tube, which is called the screen. M O N I T O R S

27. >PHOTO GALLERY< >monitors<

28. >used to produce a hard copy >the information is printed on paper and can be used when the device is off. It is also called a printout. >Dot Matrix, Ink Jet and Laser are types of printers. P R I N T E R S
