An Input device which send any kind of data to the Center Processing Unit (CPU). Today we are presenting here How to learn Computer Basic: Input Device

Input Device
Through these type device CPU takes input. There are different type of input device  such as mouse, keyboard, touch pad, scanner, microphone, Bar code reader etc.

1. Mouse
A pointing device that functions by detecting two-dimensional motion relative to its supporting surface.

2. Keyboard
A typewriter-style device, which uses an arrangement of buttons or keys, to act as mechanical levers or electronic switches that is main role of input device.

3. Scanner
A device that scans images, printed text, handwriting, or an object, and converts it to a digital image.

4. Digital Camera
A camera that takes video or still images by recording images based on an electronic image sensor.

5. Web Camera
That used for online. It take pictures online with the webcam using over 70 free fun effects.

6. Joysticks
A 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.

7. Track Ball
A trackball is a pointing device consisting of a ball held by a socket containing sensors to detect a rotation of the ball about two axes—like an upside-down mouse with an exposed protruding ball.

8. Touch Pad/ Screen
A touchpad is a pointing device featuring a tactile sensor, a specialized surface that can translate the motion and position of a user’s fingers to a relative position on screen. Touchpads are a common feature of laptop computers, and are also used as a substitute for a mouse where desk space is scarce.

9. Light Pen
A light pen is a computer input device in the form of a light-sensitive wand used in conjunction with a computer’s CRT display.

10. Bar Code Reader
A bar code reader (or bar code scanner) is an electronic device for reading printed bar codes.

11. Microphone
A microphone (colloquially called a mic or mike; both pronounced /ˈmaɪk/)[1] is an acoustic-to-electric transducer or sensor that converts sound into an electrical signal.

12. Graphic Tablets
A graphics tablet or digitizer is a computer input device that enables a user to hand-draw images and graphics, similar to the way a person draws images with a pencil and paper. These tablets may also be used to capture data or handwritten signatures.

13. Magnetic Ink Reader
This ink is magnetized and commonly called ‘magnetic ink’. It can be read by a special machine called a Magnetic Ink Character reader (MICR).

14. Optical Mark Reader
Optical Mark reading (OMR) is a process of entering data into a Computer System. Optical Mark Readers reads pencil or pen marks made in pre-defined positions on paper forms as responses to questions or tick list prompts.

15. Magnetic Card Reader
A magnetic stripe card is a type of card capable of storing data by modifying the magnetism of tiny iron-based magnetic particles on a band of magnetic material on the card. The magnetic stripe, sometimes called swipe card or mag-stripe, is read by swiping past a magnetic reading head.

16. Biometric Devices
Biometrics allow people to be identified based on unique characteristics. Examples include fingerprint scans, iris scans, and voice recognition.

17. Bluetooth
Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength radio transmissions in the ISM band from 2400–2480 MHz) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security.
