Answer Details
The unit through which the result of processed data is displayed is the output unit. An output unit is a device that receives information from a computer or other electronic device and presents that information to the user in a human-readable form, such as text, images, or sound. The most common output units are displays, printers, and speakers. For example, when you type a document on your computer and then print it, the printer is the output unit that produces a hard copy of the document. Similarly, when you play a song on your phone, the speaker is the output unit that produces the sound. The output unit is an important part of the computer system, as it allows users to interact with the processed data and make use of the results of their computations. Without an output unit, the data would be processed but the user would have no way of seeing or hearing the results.
