- 6. >allows you to scan documents, pictures, or graphics and view them on the computer. >converts an image into dots that the computer can understand S C A N N E R
- 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.

- 12. > the portion of a computer system that carries out the instructions of a computer program > it is the primary element carrying out the computer's functions. P R O C E S S I N G unit central
- 14. >incorporates most or all of the functions of a central processing unit (CPU) on a single integrated circuit M I C R O P R O C E S S O R >constructed out of small and medium-scale ICs containing the equivalent of a few to a few hundred transistors.

- 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
- 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
- 30. > used to output sound S P E A K E R S >used to connect analog audio and video components >also called a "phono connector"
