What is one of the key roles of an output device?

• A. To accept user commands
• B. To convert data into a human-readable form
• C. To transfer data between computers
• D. To enhance processing speed

Answer: (B)

One of the key roles of an output device is to convert data into a human-readable form. Output devices, such as monitors, printers, and speakers, take processed data from the computer and present it in a format that users can understand. For example, a monitor displays images and text, allowing users to view visual information, while a printer produces physical copies of documents, making digital information tangible. This function is essential for effective human-computer interaction, as it allows users to perceive and make decisions based on the results of computational processes. The other options refer to functions that are not typically associated with output devices. Accepting user commands relates to input devices, transferring data between computers concerns networking equipment, and enhancing processing speed refers to hardware improvements rather than the output function.
