Data output refers to the information produced by a computer or device after processing input data. This output can take various forms, such as text, images, or sounds, and is often displayed on screens, printed on paper, or sent to other devices. For example, when you type a document in a word processor, the final printed page is the data output of your work. In many cases, data output is essential for decision-making and analysis. Businesses use data output from software programs to generate reports, track performance, and make informed choices. Tools like Excel or Tableau help visualize this output, making it easier to understand trends and patterns.
