COMPUTER
PERIPHERAL DEVICE
A peripheral device is defined as a computer device, such as a keyboard or printer, that is not part of the essential computer (i.e.,
the memory and microprocessor).
These auxiliary devices are intended to be connected to the computer and used.

2. Group Activity : “Computer Peripherals” 1 whole sheet or bond paper Draw and List down 5 input device, 5 output devices and 5 storages devices. Give each item a short definition or function of the device.

3. A peripheral device is defined as a computer device, such as a keyboard or printer , that is not part of the essential computer (i.e., the memory and microprocessor).

4. These auxiliary devices are intended to be connected to the computer and used.

5. The Operating System is the one manages a computer's software hardware resources , including input devices such as a keyboard and mouse,

6. output devices such as display monitors, printers and scanners, network devices such as modems, routers and network connections and storage devices such as internal and external drives .

7. Types of Peripheral Devices Input device Any machine that feeds data into a computer. For example, keyboard a is an input device, whereas a display monitor is an output device. :

8. Input devices other than the keyboard are sometimes called alternate input devices. Mice, trackballs, and light pens are all alternate input devices. :

9. Keyboard A keyboard is defined as the set of typewriter-like keys that enables you to enter data into a computer or other devices.

10. Computer keyboards are similar to electric-typewriters but contain additional typing keys .

11. Mouse A mouse is a device that controls the movement of the cursor or pointer on a display screen. A mouse is a small object you can roll along a hard, flat surface. :

12. Itsname is derived from its shape, which looks a bit like a mouse, its connecting wire that one can imagine to be the mouse's tail, and the fact that one must make it scurry along a surface.

13. As you move the mouse, the pointer on the display screen moves in the same direction.

14. Trackball A pointing device. Essentially, a trackball is a mouse lying on its back. To move the pointer, you rotate the ball with your thumb, your fingers, or the palm of your hand.:

15. There are usually one to three buttons next to the ball, which you use just like mouse buttons. :

16. Light pen An input device that utilizes a light-sensitive detector to select objects on a display screen. :

17. A light pen is similar to a mouse, except that with a light pen you can move the pointer and select objects on the display screen by directly pointing to the objects with the pen.

18. Output device Any machine capable of representing information from a computer. This includes display screens, printers, plotters, and synthesizers.

19. Monitor Another term for display screen. The term monitor, however, usually refers to the entire box, whereas display screen can mean just the screen.

20. In addition, the term monitor often implies graphics capabilities.

21. Printers A printer is an output device that prints paper documents. This includes text documents , images, or a combination of both.

22. Plotter A device that draws pictures on paper based on commands from a computer. Plotters differ from printers in that they draw lines using a pen.

23. As a result, they can produce continuous lines, whereas printers can only simulate lines by printing a closely spaced series of dots. Multicolor plotters use different-colored pens to draw different colors.

24. In general, plotters are considerably more expensive than printers. They are used in engineering applications where precision is mandatory.

25. Computer Systems Design:

26. Computer design is concerned with the hardware design of the computer. Once the computer specifications are formulated, it is the task of the designer to develop hardware for the system.

27. Computer Cases : The most common system case type is the tower. Depending on the specific number of internal drive bays and the height of the tower, these cases can be further classified into mini-size, mid-size and full-size tower cases.

28. Full Tower

29. Full Tower Full-tower cases are generally big with a height that is about or more than 30 inches (more than 76 cm). The number of internal drive bays inside these cases can be between 6 and 10.

30. Mid Tower

31. Another case that might be a step down, would be classified as a mid-tower case. Mid-tower cases are the most widely used computer cases.

32. Mid Tower cases are about 18 to 24 (45 to 60 cm) inches high and they usually contain 2 to 4 internal drive bays and a similar number of external bays (for CD/DVD readers and similar ).

33. Mini Tower

34. Mini-tower usually have up to 2 or sometimes 3 internal drive bays. Mini-cases normally stand at a height of 12 to 18 inches (30 to 45 cm). Expandability is a problem with these cases.

35. Slim Line Case Slim line cases are simply tower cases turned on their sideways. They can hold a monitor on top of the case.

36. Small Form Factor (SFF) Case -are custom cases that are designed to minimize the spatial volume of a desktop computer. SFFs are available in a variety of sizes and shapes, including shoe boxes, cubes, and book-sized PCs.
