Which device produces a digital image file for storage on a computer?

• A. A printer
• B. A scanner
• C. A speaker
• D. An Ethernet cable

Answer: (B)

A scanner is the device that produces a digital image file for storage on a computer. It works by capturing physical documents or images and converting them into a digital format that can be saved and edited on a computer. The scanner uses light to read the image, which is then processed and translated into a digital file, commonly in formats like JPEG, PNG, or PDF. This process allows for convenient storage, sharing, and manipulation of the images on digital platforms. In comparison, a printer produces hard copies of images or documents from digital files but does not create digital files itself. A speaker is an output device that produces sound, and an Ethernet cable is used to connect devices within a network but does not play a role in creating digital image files.
