 Mouse usually has two or three buttons using
which the user can select options from the
mouse.
 Mainly there are two variants of the mouse,
optical mouse and mechanical mouse.

11.  Joystick is an input device consisting of a stick
that pivots on a base and reports its angle or
direction to the device it is controlling.
 Joysticks are often used to control video
games, and usually have one or more push-
buttons whose state can also be read by the
computer.

trigger, 4. extra buttons, 5. auto fire switch, 6. throttle, 7.
hat switch (POV hat), 8. suction cup.
JOYSTICK

13.  Scanner is a device that optically scans
images, printed text, handwriting, or an
object, and converts it to a digital image.
 Common examples found in offices are
variations of the desktop (or flatbed) scanner
where the document is placed on a glass
window for scanning.
SCANNER

14. { Canon’s CanoScan 9000F, a high speed flatbed
scanner.
SCANNER

15. {MONITOR, PRINTER AND
SPEAKR
OUTPUT
DEVICES

16.  A monitor is an electronic visual display unit
for computers.
 The display device in modern monitors is
typically a thin film transistor liquid crystal
display (TFT-LCD) thin panel, while older
monitors use a cathode ray tube (CRT) about as
deep as the screen size.
MONITOR

17. { Samsung SA950, a LED backlit monitor.
MONITOR

18.  Printer is a peripheral which produces a text or
graphics of documents stored in electronic
form, usually on physical print media such as
paper or transparencies.
 The printers commonly used with the
computer are the dot matrix printer, the ink-jet
printer and the laser jet printer.
PRINTER

19. { Canon Pixma MP150, a inkjet printer.
PRITNER

20.  Speaker is an electroacoustic transducer that
produces sound in response to an electrical
audio signal input.
 Speakers are used to listen to the sound files,
which can be audio, recorded by a microphone
or audio CDs.
SPEAKER

21. { Creative GigaWorks T3 2.1 speakers.

22. {MOTHERBOARD, CPU AND
GPU
PROCESSING
DEVICES

23.  Motherboard has standard circuitry that is
needed for the PC.
 It also has an extra set of expansion slots that
enable you to plug-in cards, such as modem
and sound card.
MOTHERBOARD

24. { ASUS Rampage IV Extreme, a ATX motherboard.
MOTHERBOARD

25.  CPU is the hardware within a computer system
which carries out the instructions of a
computer program by performing the basic
arithmetical, logical, and input/output
operations of the system.
 Major CPU manufacturers are AMD and Intel.
 Two typical components of a CPU are the
arithmetic logic unit (ALU), which performs
arithmetic and logical operations, and the
control unit (CU).
CPU

26. { An Intel Core i7 processor.

27.  GPU is a specialized electronic circuit designed
to rapidly manipulate and alter memory to
accelerate the building of images in a frame
buffer intended for output to a display.
 Major GPU manufacturers are AMD and
NVIDIA.

DEVICES

34.  Hard Disk is a device for storing and retrieving
digital information.
 Hard Disk consists of one or more rigid rapidly
rotating discs coated with magnetic
material, and with magnetic heads arranged to
write data to the surfaces and read it from
them.
