Output interfaces are the components of a system that allow it to communicate information to the user or other systems. They can take various forms, such as screens, printers, or speakers, and are essential for displaying results, providing feedback, or conveying data. Common examples include computer monitors, projectors, and audio output devices. These interfaces convert processed data into a format that is understandable to humans or other machines. For instance, a monitor displays visual information, while a printer produces physical copies of documents. Effective output interfaces enhance user experience by ensuring clarity and accessibility of information.
