Which of the following is prime output device of computer?

Appeared in: UPPSC 2022

Explanation

A monitor is a display screen used to provide visual output from a computer.
It is considered the primary output device because it is essential for a user to interact with the computer's graphical user interface (GUI) and receive immediate feedback.
Without a monitor or a similar display device, using a modern computer is practically impossible for most tasks.
The search results confirm that display devices are one of the most common computer output devices.

Option A: A printer is a secondary output device used to generate a hard copy (physical printout) of data. It is not essential for the primary, real-time interaction with the computer.
Option B: A plotter is a specialized output device, similar to a printer, used for producing large vector graphics, like blueprints or technical drawings. It is not a primary output device for general computer use.
Option D: A hard disk is a storage device, not an output device. Its purpose is to store and retrieve digital data persistently. It does not present data to the user in a human-readable format.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Classification of Computer Hardware as background academic context rather than a clinical decision trigger.
Understanding basic computer hardware is crucial in modern healthcare settings for using Electronic Health Record (EHR) systems, patient monitoring equipment, and telemedicine platforms.
Nurses and other healthcare professionals must be able to troubleshoot minor issues with computer peripherals to ensure continuity of care and accurate documentation.
What if? - If a clinical workstation's monitor fails, the nurse cannot access patient charts, view vital signs from monitoring equipment, or document medication administration, leading to potential patient safety risks and care delays. This highlights the monitor's role as a primary, essential device.

How to Approach the Question

First, identify the key term in the question: 'prime output device'.
Define 'output device': a piece of hardware that communicates the results of data processing carried out by a computer.
Define 'prime' (or primary): the most important or essential one.
Evaluate each option based on these definitions.
A printer and plotter produce output but are not essential for real-time interaction, making them secondary.
A hard disk is for storage, not output in the user-facing sense.
