The document discusses the main hardware components of a computer system and peripheral devices. The core internal components are the motherboard, CPU, memory and storage drives. Input devices like keyboards and mice are used to input data while output devices such as monitors, printers and speakers are used to output data. Peripheral devices are connected externally to the computer and include components like scanners, webcams and external storage drives.

3. Power Supply/PSU power supply unit, converts outlet power, which
is what the internal components require, as well as providing
appropriate voltages and currents for the various internal
components

4. As the name indicates, this is the electronic centerpiece of
the computer, everything else connects to the
motherboard.

5. central processing unit, the “brain” of the
computer, most actual computation takes place
here.

6. access memory, the “short-term memory” of a computer,
used by the CPU to store program instructions and data
upon which it is currently operating.

7. the “long-term memory” of the computer, used for
persistent storage. The operating system, and all your
programs and data are stored here.

8. device for reading/writing optical disks.

9. does processing relating to video output.

11. Input devices accept data and instructions from the user.
 Keyboard
 Mouse
 Light Pen
 Optical/magnetic Scanner
 Touch Screen
 Microphone for voice as input
 Track Ball…

12. A keyboard is the most common inputdevice.

14. A mouse is an electro-mechanical, hand-held
device. It is used as a pointer.

15. An input device that utilizes a light-
sensitivedetector to select objects on a display
screen.

16. These devices are used for automatic data
collection.

17. Touch panel displays and pads are now being
offered asalternatives to keyboard.

18. Microphone is an input device, which takes voice as input.

19. 1. Monitor (Visual Display Unit)
2. Printers
3. Plotter
4. Speakers

20. Out of all the output devices,monitor is perhaps the mostimportant
output device because people interact with this device most
intensively than others. Computer information is displayed with
monitor.

23. A plotter is a special kind of output device that, like a
printer,produces images on paper, but does so in a
different way.
