The Importance of Data Accuracy
The accuracy of data input is extremely important. There are several types of data input. They all provide different aspects of data accuracy. There is Copy and paste method, Typing of data input manually, Verbal through voice recognition & Verbal to a stenographer, importing from other resources. Handwritten & Scan tron scanners, network sharing, Bar Coding, Bar Scanners, Punch out Tads such as the one used in the presidential election in Florida.
I in the following Senerios the accuracy of data is described
A. In the Printed Questionnaires inputting data using handwritten answers that later are put through a scan tron machine is extremely accurate. By having the original and then having an electronic devise read according to where a mark is physically placed on a sheet of paper or scorecard is quick and accurate.
B. In a Telephone survey, Handwritten score sheets, using a pre-determined questions in a predetermined order is accurate by repetition. Anything out of the ordinary will stand out and be easily picked up and dealt with.
C. Bank Checks can easily be procesed by running the check through a scanning devise that reads reading the bottom of the checks for account routing information. While the actual Dollar a real life person inputs amount of the check with a ten key keypad for entering in numbers in a designated area of the check for accuracy of currency. This method is extremely fast and accurate for banks so that they can process thousands of checks in a timely manner.
D. Retail tags are marked with a bar code. Usually an Item in a retail store of thousand of items needs to identify each item respectively. So by using a bar code that put a predetermined set of #'s into a code format. Any scanner in the store can simply scan the code for each identifying # instead of remembering or writing down 6 and 8 digit #'s to identify. This intern eliminates the dyslexia and mixing #'s up.
E. Long Documents, are best inputted with a scanner or copy and paste for accuracy. This will ensure no typing or grammatical errors. Monkey see monkey do. No emotions or thoughts.
II Along with Accuracy of data there also Convience and Quality of output. For
A. Hand Held Devises a small LCD screen can easily and effectively provide a convient output. Just like having a Computer Monitor but smaller and lighter.
The Walmart is able to keep track of its inventory with the help of a little gadget called, Telson. It scans the bar code which is not just a simple thing but it is almost like an encyclopedia as it tells all the information. The power of information is hidden in a bar code. It is very important as it keeps track of all the sales for example what is being sold, when is it being sold, history, sale prices and trend prices.
The program will monitor the user input and will notify immediately of a wrong action (like a key stroke the is not valid for the particular input), will create an error file that contains the data set that contains the error to be analyzed and investigated, or the entire batch of data will be rejected, if the errors cannot be attributed to an specific record, for the user to locate issues and resubmit a corrected set.
Wolinsky, H. (2006, October). Tagging products and people. espite much controversy; radiofrequency identification chips have great potential in healthcare. Science and
This first question is the easy question and i made my mind on what methods i should pick. I pick a convenience methods even despite the flaws of creating a bias in result of an incompleted conclusion and this convenience methods also it may not represent the views of others student. But the methods itself is very lazy but the way to get people to do the survey by being up in their face and surveying two hunderd out of five thousand student that come to the liberty, really
RFID data, for example, part and serial numbers, assembly dates and support history are put away on the tags and catches which help in maintenance of equipment. RFID technology as high value for asset management and inventory systems. A barcode is a visual representation of data that is checked and utilized for data. Bar code is simple to control equipment and tool inventory. In facilities supervisors can use barcodes to link work orders, purchase orders, spare parts and equipment which can be further used to track and collect costs.
when writing an essay, report, or anything else, I type it on my computer. I can probably
This is the algorithm that the invention of Bitcoin solved. This system is very similar to the ledger that banks use to manage money electronically in their systems. While their system is controlled by a private company, Bitcoin is totally decentralized. It is not a corporation or bank deciding what is happening with your money, it is not decided by anyone buying you. It is simply confirmed using validated math and proven computer science.
are accurate and precise when measuring ingredients to insure that each portion is about the same
others involve recording or retrieving data (making a booking, enrolling a student at university looking up results etc)
Printed questionnaires Intelligent Character Recognition (ICR) would be the best choice. Its the ICR technology that allows data capture software to automatically to, read information from all types of documents - even handwritten ones. 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. Bank checks- scanning devices that recognizes bar codes are called MICR (Magnetic Ink Character Recognition) a magnetic scanning input device. ..Stair and Reynolds(2006).
Such applications might limit the use of hands in a future that has both hands preoccupied with work leaving only voice commands as a suitable means of operating many photo
LCDs are very economical; easily programmable; they have no limitation of displaying the special characters, animations and many more.
Barcodes are used everywhere around us. They are used to track products through shipment, track products at a store and speed up and enhance the checkout process, as well as allowing faster access to information. Barcodes began to be used heavily in the 1970’s. This began a great movement in the consumer industry, speeding up the checkout process and allowing easier inventory tracking. However, just like all technologies, barcodes have been enhanced many times over and are being replaced by better, more efficient systems (Bonsor).
We all use output devices in our normal day to day life, most of us use them a lot more than we may realize now that we are in school. An output device is any processing equipment used to communicate the results of data carried out by a computer or other processing devices which turns information into an easier form for us to read. (Wikipedia).
Computer technology has had a significant impact on retail stores. All but the smallest shops have replaced the old-fashioned cash register with a terminal linked to a computer system. The terminal may require that the clerk type in the code for the item; but more and more frequently the checkout counter include a bar-code scanner, a device that directly reads into the computer the UPC printed on each package.
