Accuracy Of Data

In today's society, the collection and dissemination of information by means of computer technology is increasing every day. The accuracy of the data is extremely important which is why it is necessary to choose the correct method to precisely process the information that is input as well as create consistent information that is extracted. In order to determine the best method, it is necessary to understand the primary functions of the various types of data and hardware.

Printed questionnaires are best computed by Optical Readers. An optical reader interprets images by scanning and formatting the information into data the computer can understand and use. Telephone surveys are usually conducted with voice recognition devices. Both methods are superior to manual collection of data and minimize potential mistakes while inputting the information into a useable form for the computer to store and be retrieved at a later date. Bank checks are encoded with MICR (Magnetic Ink Character Recognition) so that the checks can be easily read and processed rapidly. This reduces the number of errors that were being made by manually inputting incorrect information and causing revenue to be lost because of input mistakes. POS devices are used to read retail tags and calculate many things about the item, including the price or the department that should receive credit for the sale or update the inventory count. This aids in the reduction of miss-keyed items and increases the speed of the completion of the sale. “By helping track inventory, they reduce "shrinkage" and employee theft. Automatic price tracking improves price accuracy over traditional cash registers.” (Exchange.com, 2007) Long documents are best produced on a high quality, high volume printer otherwise the time spent printing would be counterproductive.

Output quality and convenience are important and different methods can render different results. A hand held computer offers ease of use because it is transportable. The LCD flat panel screen offers good resolution for the limited viewable area while wireless technology compliments the portability of the unit. Color photographs are best produced with a high end printer. Depending on the quality of the printer, the greater the number of color cartridges the printer uses, the better the color quality of the photo. Resumes produced on a laser printer and quality paper achieve a finished and professional looking document. Memorandums are best sent by email transmission. This method of communication guarantees the information will reach the recipient immediately.
