There are many different ways to input data into a computer. A few examples of types of data that need to be inputted into a computer are printed questionnaires, telephone surveys, bank checks, retail tags, and long documents. The best way to input a printed questionnaire into a computer system is by optical data readers. This method works the best because people just fill in circles with a pencil and a machine scans them and reads them, which automatically inputs the data in the system. The method of input for telephone surveys is by a voice-recognition device. This would work best because it doesn't take individual people to call people and ask questions. The questions can be recorded and answers recognized by this input device and recorded into the computer system. Using Magnetic Ink Character Recognition Devices best scans bank checks. These devices just scan the bar code at the bottom of the check and tell the banks which check is being scanned. This works the best because it keeps the bank from getting swamped by the numerous checks that go through banks everyday. Using bar code scanners best scans retail tags.

The LCD monitor is small with high resolution and can be used to run programs on a small handheld computer. A color photograph, resume, memorandum, statistical reports, and company annual reports are all best printed by a laser printer because each of these needs to be produced hardcopy at a high resolution. A laser printer prints a finished product that is high resolution and professional.
