  • Essay / Data and Storage - 1048

    Many aspects of computing are important: the accuracy of data entry, the convenience and quality of output, the optimal storage devices, and the speed of data processing. a computer. What are all these things and what are the best methods or types? Data Entry Accuracy of data entry is fundamental to ensuring that the information system will be able to properly automate the collection of information and that the end user is aware and understands how the information should be recorded . Stair and Reynolds (2006) argue that “keying can be a manual or automated process. A scanner at a grocery store that reads barcodes and enters the item and price into a computerized cash register is a type of automated entry process. Regardless of the entry method, accurate entry is essential to achieve the desired result. » Printed questionnaires must be produced on machine-readable paper and scanned by scanners capable of optical mark recognition (OMR) or optical character recognition (OCR) to convert the results into a digital format that is automatically placed in a database for storage. Queries can then be used to query or collect information from questionnaires. Telephone surveys should consist of specific questions that require simple answers that can be entered by pressing buttons on a touch-tone telephone. Users who do not have a touch-tone telephone should be allowed to respond verbally via an interactive voice recognition (IVR) system. Bank checks must be printed on machine-readable paper using magnetic ink so that machines can quickly and accurately scan the document and convert the data into a digital format. Additional security measures such as watermarks and holograms may be used depending on the level of...... middle of paper ...... hard drives - look for time and data throughput. Data on a floppy disk is generally slower than on CD-ROMs and is generally used for storage purposes. Many of the same concepts apply to floppy disks and hard drives and CD-ROMs: searching for time and data everywhere. Many aspects of computing exist today, some being cutting edge while others are becoming obsolete. What is most important is the accuracy of data entry, convenience and quality of output, optimal storage devices and processing speed of a computer. ReferencesLaurie J. Flynn (2005).
