Which output device converts digital information from a computer into precise pictorial form on paper, commonly used for engineering drawings, architectural plans, and large-format graphics?

Difficulty: Easy

Correct Answer: Plotter

Explanation:


Introduction / Context:
Computers can produce visual output on physical media. For technical drawings and large-format graphics, a specialized device is preferred over standard printers. Understanding which device is designed for high-precision vector output is essential in computer graphics, CAD, and engineering contexts.


Given Data / Assumptions:

  • We need an output device that renders images on paper.
  • Use case involves pictorial/graphic form, often with precision requirements.
  • Options include both input devices and legacy devices.


Concept / Approach:
A plotter is an output device that draws images using vector commands, historically with pens moving over paper. Modern wide-format plotters use inkjet technology but still target high-resolution, large-format output for CAD drawings and maps. This differs from typical desktop printers and unrelated input devices such as mice or touch panels.


Step-by-Step Solution:
Identify device category: requires producing graphics on paper.Eliminate input devices (mouse, touch panel) and legacy punching devices that are not for pictorial output.Select the device explicitly built for precise graphical hardcopy: the plotter.


Verification / Alternative check:
Common applications include architectural blueprints, circuit schematics, and GIS maps. Plotters are standard equipment in engineering and design offices for these tasks.


Why Other Options Are Wrong:

  • Mouse: Input pointing device, not output.
  • Touch panel: Input interface, not output to paper.
  • Card punch: Legacy input/archival medium; not a graphics output device.
  • None of the above: Incorrect because ‘‘Plotter’’ fits perfectly.


Common Pitfalls:
Confusing general printers with plotters. While modern printers can print graphics, plotters specialize in precision vector or large-format technical output.



Final Answer:
Plotter
