DEVICES ?
Input devices are devices responsible for
sending instructions, data and command
to the computer system and allows the
user to control it .
This device enable interaction between
the user and the computer .

2. Mouse
3. Joystick
4. Scanner
5. Barcode Reader
6. Other input devices

4. KEYBOARD
A computer keyboard is an input device used to enter
characters and functions into the computer system by
pressing buttons, or keys. It is the primary device used to
enter text. A keyboard typically contains keys for individual
letters, numbers and special characters, as well as keys for

7. SCANNER
Scanner is an input device that
uses a light beam to scan
codes, text, or graphic images
directly into a computer or
computer system . It captures
documents such as
photographs and text.
There are basically three types
of scanners:
a) Drum Scanner
b) Flatbed Scanner
c) Handheld Scanner

8. BARCODE READER
A barcode reader is an
optical hand-held input
device that is used to read
the information from the
barcode pasted on the
product and decode the
information in a human-
readable format. It is also
used to upload the details
of the product in the
database.

9. OTHER INPUT DEVICES
MICROPHONE
LIGHT PEN
DIGITAL CAMERA
TOUCHSCREEN
