What type of device is a scanner considered?

A scanner is classified as an input device because its primary function is to convert physical documents, images, or photographs into digital data that can be processed, stored, and managed by a computer. When a scanner scans an image, it captures the visual information and translates it into a digital format, allowing the user to edit, share, or store it on a computer.

In the context of data processing, input devices are essential for introducing data into a computer system, which is exactly what scanners do. They represent a source of input for digital documents, making them integral to tasks such as digitizing paper files or capturing high-quality images for graphic design.

While scanners can be connected as peripheral devices and are sometimes considered when discussing storage due to their ability to complete tasks that involve saving scanned images, their fundamental role remains that of an input device.
