what is output in computer

Output in computer refers to any information processed by and sent from a computer or electronic device. It is the visual, auditory, or tactile perceptions provided by the computer after processing the provided information. Without output that a human could see, feel, or hear, a human could not interact with the computer. There are four basic types of output: audio output, graphics output, text output, and video output. Examples of output devices include monitors, printers, speakers, headphones, projectors, and tactile output devices. Other forms of output include voice, microfilm, and various forms of graphics.
