What is the function of a scanner?

A scanner is a device that converts physical documents and images into digital format by capturing their visual information. When it operates, the scanner utilizes optical sensors to scan an image and translate it into digital data, creating a representation that can be viewed, edited, and stored on a computer. This digital representation allows for easier sharing and manipulation of images, making it essential in various applications, such as document management and digital archiving.

The other options do not accurately reflect the primary function of a scanner; while printing is done by printers, storing documents in the cloud involves cloud storage services, and editing photographs is typically performed using specialized software rather than the scanner itself.
