data input
1. Prepare a paper explaining the following. Only provide an APA cover sheet and reference page. List the questions and answers in the same form as shown below. Accuracy of data input is important. What method of data input would be best for each of the following situations and explain why:a. Printed questionnaires - The best method for data input would be a keyboard, because it permits one to produce the required test that formulates the questionnaires.b. Telephone survey-voice recognition is best because a voice input device can be programmed to distinguish answers spoken into the receiver allowing it to all be completed by computers.c. Bank checks- scanning devices that recognizes bar codes are called MICR (Magnetic Ink Character Recognition) a magnetic scanning input device. This system reads the numbers at the bottom of the checks and will mechanically make modifications to the correct accounts. A MICR input system will magnetize the information at the bottom of the check for simple interpretation.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 manual input if numbers into a keypad is not necessary. Eit
Tapes are sequential-access media, which means that to get to a particular point on the tape, the tape must go through all the preceding points. Explain what situations are appropriate for the following devices and explain why:a. Unlike most hard disks, floppy disks (often called floppies or diskettes) are transportable, because you can remove them from computer to computer. Primary storage is from all types of input devices, responsible for secondary storage as well. Tape - A magnetically coated strip of plastic on which information can be encoded. Floppy disk- Is a soft magnetic diskette. Color photograph- A high-resolution CRT monitor and a plotter. Hand held Computer - This output device would be a USB connection to a desktop computer. Laser produces the best quality of document and prints clean and precise, where as a desktop can be a little untidy in its appearance at times. They key boards are made to make the users more comfortable and less fatigue. The bar codes are needed on them for this to properly work. Many disk drives recover their performance through a procedure called caching and is mainly used for operational systems.
