Explanation by: Admin

Microfilm reader is a device used to read microfilm, which stores documents in miniature form.

  • It is considered a COM (Computer Output Microfilm) device because microfilm is often created directly from computer data for archival purposes, and the microfilm reader is used to view this output.

Other options:

  • (A) OCR (Optical Character Recognition): OCR devices convert printed or handwritten text into machine-readable text.
  • (C) MICR (Magnetic Ink Character Recognition): MICR devices are used to read characters printed in magnetic ink, mostly used in banking (e.g., on cheques).
  • (D) None of the above: Incorrect, as (B) is the right choice.

Correct Answer: (B) COM device
