KEYBOARD
A keyboard is an input device, partially modeled after the
typewriter keyboard.

9. 
TYPES OF KEYBOARD
KEYBOARD
STANDARD(QWERTY) NON-STANDARD

10. 
STANDARD KEYBOARD
•A basic computer keyboard that does not have any advanced
features has 84 keys.
• The multimedia computer keyboard has 101 keys and these keys
are often referred to as shortcuts or hot keys.
• Some multimedia keyboards have 104 keys and such devices
provide more features as compared to a keyboard with 101 keys.

11. 
NON-STANDARD KEYBOARD
•Non-Standard Keyboard let the user type in characters or commands
by pressing a combination of keys.
• The chorded keyboard design is typically used for hand-held
computers that cannot accommodate standard-sized keyboards.

12. 
MOUSE
A mouse is a pointing device which is used
to control & move the cursor on the screen.
“The first computer mouse underside view
held by inventor Douglas Engelbart”.

13. 
MOUSE BUTTONS
This input device controls the
cursor on the computer screen.
It has two or three buttons and
a cable connecting it to the
computer. It is quite easy to
operate a mouse, the user
simply moves the cursor along
the table. Once the cursor is at
the desired location, the user
can give instructions to the
computer by clicking the
button.

SCANNER
•A scanner is a device that
optically scans images, printed
text, handwriting, or an object,
and converts it to a digital
image.
• Scanners typically read red-
green-blue color (RGB) data
from the array. This data is
then processed with some
proprietary algorithm to correct
for different exposure
conditions, and sent to the
computer via the device's
input/output interface

BIOMETRICS
• When referring to computers and
security, biometrics is the identification
of a person by the measurement of
their biological features. For example, a
user identifying themselves to a
computer or building by their finger
print or voice is considered biometrics
identification.
• When compared to a password, this
type of system is much more difficult
to fake since it is unique to the person.
Below is a listing of some known
biometric devices.
