Which optical device is used to convert printed text and images into digital formats?

• A. Printer
• B. Scanner
• C. Camera
• D. Projector

Answer: (B)

The device that converts printed text and images into digital formats is a scanner. Scanners work by using a light source to illuminate the document and capture the reflected light through sensors, which then translate this information into digital data. This allows for the creation of digital copies of printed materials, making it possible to store, edit, or share them electronically. In contrast, a printer produces hard copies of digital documents, a camera captures images and videos in digital format but primarily for photographic purposes, and a projector displays images or videos onto a surface, usually for presentations. Only the scanner specifically addresses the conversion of physical documents into digital files, making it the correct choice.
