Accuracy of Data Input Is Important. What

Accuracy of data input is important. What method of data input would be best for each of the following situations and why:

Printed questionnaires - Beyond using a manually-based approach to capture this data and transcribing it onto computer screens, the best possible approach would be code the questionnaire so responses could be read with Optical Character Recognition (OCR) software (Nibler, 1993).

Designing an on-screen software application that will allow for those giving the survey to capture their responses directly on-screen as the respondents provide their answers (Nibler, 1995).

Bank checks -- It is a best practice to rely on the Magnetic Ink Character Recognition (MICR) codes across the bottom of a check to ensure account number and routing number are correctly read. In addition to MICR codes, companies are increasingly using OCR to read the figures on the check as well.

Retail tags -- the best possible approach for managing data input from retail tags would be the use of bar codes (Roark, Miguel, 2006). Many retailers are progressing beyond this approach however and are using Radio Frequency Identification (RFID) codes as well.

Long documents -- The best possible input strategy is OCR for this task, as the pages could be quickly scanned and turned into digital form for ease of use and long-term storage.

Convenience and quality of output are important. Explain what method of output would be best for each of the following situations and why:

Hand-held computer -- A standard Liquid Crystal Display (LCD) would work perfectly, or attached the device to a flat screen monitor for easier viewing.

Color photograph -- This is an area of technology this progressing very rapidly with inkjet technologies today having the quality of laser printers from decades ago. The best possible printer to use would be a high-resolution inkjet printer for this task. There are also companies actively using offset color printers at a much higher quality costs yet the quality is superior to another of technology (Welch, 2011).

Resume -- A standard monochrome inkjet or color printer would be fine for printing a resume.

Memorandum -- Just as with a resume, a memorandum is best produced at a very low cost-per-copy, which is typically where monochrome inkjet and laser printers deliver the greatest value.

Statistical report -- A high volume laser printer with color capabilities would be the best possible technology for a statistical report as this technology has the ability to mix text and graphics on the same page and also supports color (Stead, 1985).

Company annual report -- This needs to be extremely high quality, and therefore would best be produced on an offset printing press (Welch, 2011).

Different types of storage devices are optimal for different situations. Explain what situations are appropriate for the following devices and why:

Hard disk -- For long-term storage of larger files and those that need to be secured, a hard disk is the best storage medium there is.
