Which of the following is NOT a type of output?

Output refers to the information that a computer produces as a result of processing input data. When we look at the types of output, printed output involves tangible results like documents and reports created by printers. Audio output pertains to sound generated by devices like speakers, while video output includes visual representations provided on screens or monitors.

Input output is not a type of output; rather, it describes the overall process of a computer receiving data (input) and producing results (output). It addresses the entire interaction between the user and the computer system rather than focusing on one specific type of output product. This distinction emphasizes that while printed, audio, and video outputs are specific modalities through which information is conveyed, "input output" encapsulates the broader concept of how systems handle data in both directions.
