ITPEC IP October 2023 Question 23

OCR — an Optical Character Reader reads printed or handwritten characters and converts them into character codes.

The device scans the paper as an image, then recognises the shape of each character and outputs its code, so the text can be edited and searched on a computer. It is used to read application forms, postal codes and handwritten entries.

Answer (c)

Why not others:

• •(a) BD-R — a write-once Blu-ray disc, a storage medium; it records data but recognises nothing
• •(b) CD-R — a write-once compact disc, likewise a storage medium
• •(d) OMR — an Optical Mark Reader detects whether marks are filled in at fixed positions, as on mark-sheet answer forms; it does not read the shapes of characters

Key rule: OCR reads characters (shapes to character codes); OMR reads marks (filled or not at fixed positions); BD-R and CD-R are recordable media, not input devices.
