Peripheral devices are connected either internally or externally to a computer. They allow input of data and output of processed information. Some key input peripheral devices discussed are biometric devices, optical mark readers, magnetic stripe cards, radio frequency identification, and sensors. Important output peripheral devices mentioned are liquid crystal displays, light emitting diodes, plotters, and 3D printers. The document provides details on each of these peripheral devices, including their purpose and examples.

10. Magnetic Ink Character Recognition
Magnetic Ink Character Recognition (MICR) is a technology used
to read and process cheques.
The benefits of the technology include enhanced security against
fraud and mechanization of check processing.

13. Radio Frequency Identification (RFID)
Radio Frequency Identification (RFID) is a type of passive
wireless technology that allows for tracking or matching of an
item or individual.

15. Sensors
A Sensor is an input device which provides an output (signal)
with respect to a specific physical quantity (input).

17. After class Activity - 2
Research about
Different types of sensors
Voice Recognition System
Face Recognition
Smart cards
A Debate will be conducted during the class
about the advantages and disadvantages of
such peripherals
20. LiquidCrystal Display (LCD)
Liquid Crystal Display is a flat, electronic device generally
used as a screen in televisions, computers, smartphones and
display signs for producing still and movable images.
21. Light Emitting Diode (LED)
LED screens work in a similar way to LCD screens but with one major
difference, the light source.
Small LED bulbs are used to provide light to the LCD pixels, not
fluorescent tubes.
22. OrganicLight Emitting Diode (OLED)
An organic light-emitting diode (OLED), also known
as organic electroluminescent (organic EL) diode is a light
emitting diode (LED).
How do LED and OLED differ?
In LED LCD screens use a backlight to illuminate their pixels,
while OLED's pixels produce their own light. The light of an
OLED display can be controlled on a pixel-by-pixel basis.
23. Plotter
A plotter is a printer that
interprets commands
from a computer to
make line drawings on
paper with one or more
automated pens.
24. 3D Printer
3D printing uses computer-
aided design to create three-
dimensional objects through a
layering method. Sometimes
referred to as additive
manufacturing, 3D printing
involves layering materials,
like plastics, composites or
bio-materials to create objects
that range in shape, size,
rigidity and color.
