Which of the following is NOT a commonly used input device ?

  • (A) Keyboard
  • (B) Microphone
  • (C) Printer
  • (D) Scanner

Printers are output devices, used to produce physical copies of electronic data. The passage discusses input devices, which are used to enter information and instructions into a computer.

Introduction to Input and Output Devices

In the realm of computing, the roles of input and output devices are crucial for the overall functionality of a computer system. While printers are output devices used to produce physical copies of electronic data, input devices are essential for entering information and instructions into a computer.

What Are Input Devices?

Input devices are hardware components that allow users to interact with a computer by providing data and control signals. Common examples include keyboards, mice, scanners, and microphones. These devices play a pivotal role in enabling users to execute commands, enter text, and manipulate graphical elements within a software environment.

The Role of Output Devices

Output devices, on the other hand, are designed to present data processed by the computer in a human-readable form. Printers, for instance, convert digital documents into printed sheets of paper. Other output devices include monitors, which display visual information, and speakers, which produce sound. These devices help bridge the gap between digital data and the physical world.

Interplay Between Input and Output Devices

The symbiotic relationship between input and output devices is essential for the seamless operation of a computer system. Input devices capture user instructions and data, which the computer processes and subsequently conveys through output devices. This interaction enhances the user experience by facilitating efficient communication between the user and the computer.

Conclusion

Understanding the distinct yet interconnected roles of input and output devices is fundamental for anyone delving into the world of computing. While input devices like keyboards and mice gather information, output devices such as printers and monitors render the processed data into a usable form. This dynamic ensures that computers remain versatile tools capable of handling a wide array of tasks.
