Output refers to any information processed by and sent from a computer or electronic device. It can be viewed on a computer monitor screen, heard through speakers, or printed on paper. An output device is any piece of computer hardware that converts information into a human-perceptible form or, historically, into a physical machine-readable form for use with other non-computerized equipment. There are four basic types of output: audio output, graphics output, text output, and video output. Examples of output devices include display screens, speakers, printers, and projectors.
It is important to note that output can also refer to the result of an activity a company carries out, but which does not have a measurable impact on its customers. In this context, output describes the quantity or volume of a product or service produced by a company.
In summary, output can refer to the information produced by a computer or electronic device, as well as the quantity or volume of a product or service produced by a company.
