1. Accuracy of data input is important. What method of physical data input (i.e hardware device) would be best for each of the following situations and explain why:

Printed questionnaires

Telephone survey

Bank checks

Retail tags

Long documents

a. Printed Questionnaires - The best method for data input would be a keyboard. The reason the keyboard would be best is because it enables some one to create the needed test that makes the questionnaires.

b. Telephone Survey - The best method of data for this situation would be a voice input device. The reason this would be the best choice is because a voice input device can be programmed to recognized answers spoken into the phone. By doing this a live person does not have to conduct the survey, it can all be done my computer.

c. Bank Checks - The best input for bank checks would be MICR (Magnetic Ink Character Recognition) a magnetic scanning input device. Because banks have to deal with large volume of checks they need a system that can read checks fast. This system reads the numbers at the bottom of the checks and will automatically make adjustments to the proper accounts. A MICR input system will magnetize the numbers at the bottom of the check so the system can read them.

d. Retail Tags - The best data input for retail tags would be a bar code scanner. This is called an optical scanning input device. By using a bar code scanner the user does not have to riley on manually inputting numbers into a keypad. They can use either a handheld or fixed scanner to do this. The tags must also have these bar codes on them for this to properly work. The bar codes have specific codes that apply to certain types of merchandise.

e. Long documents - The data system for this would also be a typewriter. But because this document is longer and often takes much more time to type and create and different type of keyboard is needed. An ergonomics keyboard would be the best choice. They key boards are made to make the users more comfortable and less fatigue. They are made specifically comfort, ...
