To answer this question, you need to understand the concepts of OCR (Optical Character Recognition), OMR (Optical Mark Recognition), and MICR (Magnetic Ink Character Recognition).
Let's go through each option to understand why it is correct or incorrect:
Option A) OCR (Optical Character Recognition) - This option is correct because OCR technology is specifically designed to capture and convert printed text into digital format. OCR devices use optical sensors and software algorithms to recognize and interpret characters from printed documents.
Option B) OMR (Optical Mark Recognition) - This option is incorrect. OMR technology is used to detect and interpret marks or checkboxes on paper forms, such as multiple-choice answer sheets or surveys. It is not designed to directly input printed text.
Option C) MICR (Magnetic Ink Character Recognition) - This option is incorrect. MICR technology is primarily used in banking systems to recognize and process information from checks. It is not used for directly inputting printed text.
Option D) All of the above - This option is incorrect. While OCR is the correct answer as it directly inputs printed text, OMR and MICR do not perform this specific function.
The correct answer is Option A) OCR. This option is correct because OCR devices are specifically designed to directly input printed text by capturing and converting it into digital format.
