Which of the following represent output devices?

Output devices are hardware that convey information from a computer to the user. They take data from the computer and convert it into a form that is understandable and usable by people. A monitor is a visual display unit that shows images, text, and videos, allowing users to see and interact with the software and data being processed. Similarly, a printer converts digital documents or images into physical copies on paper, providing a tangible representation of the data.

In contrast, the other choices represent input devices or storage mediums rather than output devices. A keyboard and mouse are used to input data into a computer. A scanner captures images and text from physical documents to convert them into digital format, which is also an input function. A microphone captures sound and converts it into digital audio, allowing users to input vocal information into a computer. Lastly, a camera and film involve capturing images but do not serve to output data from a computer. Therefore, the combination of a monitor and printer effectively represents output devices in this context.
