Accuracy Of Data Input, Quality Output, Storage Devices, And Speed Of A Computer

850 words - 3 pages

IntroductionThis Paper will discuss the importance of data entry and witch is the best method for data input for a variety of methods. Also this paper will look at convenience and why the quality of output is important. There are different types of storage devices that will be examined, to see which ones are appropriate for a variety of devices. And this paper will give an explanation of the role of hardware in determining the speed of a computer.Accuracy of Data InputData plays an important role for computers and how well they perform. The accuracy of data entry is very important, in that if bad data in, bad data out. That is to say if data entry is done improperly then the out put will flawed. And the data may be hard or imposable to retrieve. Or you might be able to retrieve it but the data will reflect inaccurate information. There are several ways that data can be input into the computer one is called Optical Data Reader. The Optical Data Reader can be used to input the information from a printed questionnaires or test. A telephone survey could be conducted with Voice Recognition Devices, witch are used to recognize human speech, record the responses and enter them into a database. Financial institutions use another data entry method, Magnetic Ink Character Recognition (MICR) device. Banks use MICR to process checks, loan applications and bank statements in order to reduce the time it takes to manually read and type in these types of documents. For industries that have large inventories or retail sales use bar code scanners as another form of data input. A laser scans the bar code label and transfers the data for fast and easy processing. Some organizations have to deal with long documents from time to time. If the organization is producing the document themselves, it is best to enter the data into a word processor for easy editing. However, there are times when an organization receives a document pre-printed and wants to input the data into a computer. In this case it is best to scan the document and process it with an optical character recognition program (Stair, Reynolds 2006).Convenience and Quality of OutputNot only dose one need to get information into a computer, but also one will need to get it out, and in different formats. Some methods are more appropriate than others depending on the type of information that needs to be output. Output from a handheld computer will usually be for display this can be output on to a small LCD...

Using magnetic disks gives you a couple of options to store data. The hard disk and the floppy disk; the former is usually inside the computer, and it has greater storage capacity. At the same time its design allows for faster access of data. Information that does not need to be portable and is larger in size should be

1274 words - 6 pages This paper proposes a new criterion for the input/output-to-state stability (IOSS) of interfered direct-form digital filters with finite wordlength nonlinearity based on an augmented Lyapunov function. Without external interference, the output-to-state stability (OSS) and asymptotic stability of direct-form digital filters with finite wordlength nonlinearity are also guaranteed under the proposed criterion. This criterion is expressed by linear
