__________ is a reading device that reads printed text by scanning it character by character.

Correct option is D

An Optical Character Reader (OCR) is a device that reads printed text by scanning it character by character. It converts the text into machine-readable data, enabling the text to be edited, searched, and stored digitally. OCR is widely used in document digitization and text recognition.

Important Key Points:

1. OCR converts printed or handwritten text into digital form by recognizing individual characters.
2. It is commonly used for digitizing documents, scanning forms, and automating data entry processes.
3. Unlike other input devices, OCR specifically focuses on reading text.
