Question 222 of 319

Use the information below to answer this question
I. - Mouse II. - Keyboard III. - Scanner IV. - Joystick.
The input devices used to capture finger print is?

  • A. I
  • B. II
  • C. III
  • D. IV

Correct Answer: C

Explanation
The correct option for the input device used to capture fingerprints is C. III (Scanner). Detailed Explanation:
  1. Understanding Input Devices:
  2. Input devices are hardware components that allow users to input data into a computer system. Common examples include mice, keyboards, scanners, and joysticks. Each of these devices serves a different purpose.
  3. Analyzing the Options:
  4. I. Mouse: A mouse is primarily used for pointing, clicking, and navigating through graphical user interfaces. It does not capture biometric data like fingerprints.
  5. II. Keyboard: A keyboard is used for typing text and commands into a computer. Similar to the mouse, it does not have the capability to capture fingerprints.
  6. III. Scanner: A scanner is a device that converts physical documents and images into digital format. There are specialized scanners, known as fingerprint scanners, that are designed specifically to capture the unique patterns of a person's fingerprints.
  7. IV. Joystick: A joystick is typically used for gaming and controlling movement in simulations. It does not have the functionality to capture fingerprints.
  8. Why Option C is Correct:
  9. Fingerprint scanners are a type of scanner that uses optical, capacitive, or ultrasonic technology to read the unique patterns of ridges and valleys on a person's fingertip. This data is then converted into a digital format that can be processed by a computer for identification or authentication purposes. Therefore, option III (Scanner) is the correct answer.
  10. Why Other Options are Incorrect:
  11. Option A (Mouse): As mentioned, a mouse is not designed for capturing biometric data. It is strictly for navigation and inputting commands.
  12. Option B (Keyboard): A keyboard is used for text input and does not have the capability to capture fingerprints.
  13. Option D (Joystick): A joystick is used for controlling movement in games and simulations, and it does not serve any function related to capturing fingerprints.
Common Pitfalls:
  • Students may confuse general scanning devices with specialized fingerprint scanners. It’s important to recognize that not all scanners are designed for biometric data capture.
  • Misunderstanding the primary functions of input devices can lead to incorrect answers. Always consider the specific capabilities of each device.
Revision Summary:
  • Input devices allow users to input data into a computer; examples include mouse, keyboard, scanner, and joystick.
  • Fingerprint scanners are specialized devices that capture biometric data, making option III (Scanner) the correct answer.
  • Other options (mouse, keyboard, joystick) do not have the capability to capture fingerprints.
  • Understanding the specific functions of each input device is crucial for answering related questions correctly.
