Examples of output devices are printers and display screens. (Stair & Reynolds, 2006). In business, examples of common outputs are documents such as manager reports or employee paychecks. Depending on the hardware being used or type of output desired, different situations may require various forms of output from different output devices. Output on a handheld computer may be limited to what is displayed on the screen. However, if the...
