Paper Introduction: Accuracy of data input is important What method of data output would bebest for each situation explain why The first situation involves the use of printed questionnaires Printed questionnaires create problems for two reasons First such questionnaires are completed by respondents usually by written notation Second the responses to such questionnaires must be read transcribed and entered into a digital analysis system Hand-entered notations are difficult to read The process of reading transcribing and entering data into a digital analysis system creates Text of the Paper: The entire text of the paper is shown below. However, the text is somewhat scrambled. We want to give you as much information as we possibly can about our papers and essays, but we cannot give them away for free. In the text below you will find that while disordered, many of the phrases are essentially intact. From this text you will be able to get a solid sense of the writing style, the concepts addressed, and the sources used in the research paper. The second situation involves the use of a telephone survey. A character scanning device coupled with optical character recognition (OCR) software is the most efficient and the most accurate means of entering data from long documents. 81).3. Explain the difference between primary storage and secondary storage. Second, the responses to such questionnaires must be read, transcribed, and entered into a digital analysis system. For convenience and quality, a statistical report can be transmitted to a high-definition printer to assure that the numerical output is clearly defined and readable. Explain the role of each of the following in determining the speed of a computer: The first factor is RAM. In contrast to primary storage, secondary storage considered within the context of digital information processing refers to read only memory (ROM). Clock speed refers to the rated speed of the CPU (as opposed to the rated speed of RAM chips). Photographic editing software should be used to prepare the digital photograph for transmission to the printer. The fourth situation involves the use of retail tags. The fifth factor is data stored on a floppy disk. The fifth situation involves the use of long documents. For convenience as well as for quality, a memorandum should be prepared using word processing software. Data on a hard disk must be accessed in order to be used. 6 ).2. Accuracy of data input is important. The third situation involves the use of bank checks. OMR accuracy can suffer if respondents do not exercise care in completing the forms (Stair & Reynolds, 2 3, p. The third item is a memorandum. For both convenience and quality, a resume should be prepared in a portable document format (PDF) digital document file, which is then transmitted to a high-quality laser printer. The third factor is data stored on a hard disk. RAM is faster and more costly than ROM. What method of data output would bebest for each situation (explain why)? M., & Reynolds, G. These devices can read the retail tags and send the data directly to a storage device (Stair & Reynolds, 2 3, pp. This approach assures accuracy by eliminating the potential for human recording errors. The capacity of RAM affects the volume of data that can be processed at one time. The best data input method is to record the responses of the interviewee with a voice recognition device and voice recognition software that stores the information directly on to a computer hard disk. Floppy disk access is slow compared to all other data storage devices, and floppy disks are severely limited in relation to capacity.ReferencesStair, R. The first situation involves the use of printed questionnaires. 6 ). Convenience and quality of output are important. Fundamentals of information systems. The second factor is clock speed. 59). These devices are designed to recognize the magnetic coding placed on bank checks (Stair & Reynolds, 2 3, p. 33, 6 , 62). The capacity) of RAM chips and the speed of the RAM chips affect the speed of processing. The memorandum then can be printed on a high quality ink jet printer or a laser printer on 2 -pound bright paper (Stair & Reynolds, 2 3, p. The fifth storage device is tape. Data on a floppy disk must be accessed in order to be used. 49, 54, 66, 9 ).4. Data on a CE ROM must be accessed in order to be used. This function may be accomplished by using a digital camera, or it can be accomplished by using a color photographic scanner (Stair & Reynolds, 2 3, pp. Boston: Course Technology. (2nd ed.). The second storage device is the floppy disk. The Best output device to collect, enter, and store data from bank checks, thus, is the device developed for the process - a magnetic ink character recognition (MICR) device. Different types of storage devices are optimal for different situations. The fourth item is a statistical report. ROM stores data in the form of documents created through the use of application programs. Primary storage considered within the context of digital information processing refers to random access memory (RAM). RAM holds the instructions and other data required to allow the central processing units (CPUs) in computers to interact with the requests and commands of application programs. If the original documents are high- contrast with few notations, OCR accuracy is high (Stair & Reynolds, 2 3, p. The second item is a resume. The process of reading, transcribing, and entering data into a digital analysis system creates several opportunities for error. A PDF document can be forwarded to a recipient in digital format (convenient for both sender and receiver in many cases) or as a high- quality printed document. Hard disk designs incorporate data caches and rotation speeds that affect the speed of processing time. Applications, operating systems, and files that are used on regular and ongoing bases should be stored on hard disks. 1. Retail tags identify products and their locations. Another issue involves digitizing the image. The system involves encoding the essential information related to a check (account, bank, check number, and so forth) on checks, as well as optical reading and digitally encoding additional information (monetary amount, as an example) on the check once used. A scanning device coupled with optical mark recognition (OMR) software is the best method to assure accuracy when entering data from printed questionnaires. Company annual reports should be prepared in a portable digital document format file, which is then transmitted to a high-quality color laser printer. The output quality for a color photograph is highest when a high quality color photographic printer is used to print the photograph on photographic quality paper. The fourth factor is data stored on a CD ROM. First, such questionnaires are completed by respondents (usually by written notation). 81). To assure output quality, annual reports should be printed on heavy glossy paper (Stair & Reynolds, 2 3, p. 82). Retail tags use bar codes for these purposes. (2 3). Statistical reports are transmitted to printers directly from statistical application programs (Stair & Reynolds, 2 3, p. Explain what method of output would be best for each of the following and explain why. Translation errors may occur, however, if the voice recognition software is not adjusted for the speech of the interviewees (Stair & Reynolds, 2 3, p. The fifth item is a company annual report. The first item is a color photograph. Tape storage is most suitable for masses of data that need to be duplicated for off-site storage or for use in system restoration.5. A system was developed especially for the digital processing of bank checks. W. Large files and large applications that are used infrequently, that must be physically moved, that serve as back-up copies, or are used in portable devices are suitable for CD ROM storage. ROM provides greater capacity and greater flexibility than RAM. RAM speed determines how fast the RAM chips can function with the input-output system. Small files and small applications that are used infrequently or that must be physically moved are suitable for floppy disk storage. Bar code scanners offer the most accurate way to collect and store data from retail tags. CD ROM-based data takes longer to access than is true of data on a hard disk in almost all instances, and they have limited data capacity compared to hard disks. Explain what situations are apporpiate for the following devicies and why: The first storage device is the hard disk. Printed questionnaires create problems for two reasons. To assure output quality, the resume should be printed on bond paper. Each form of storage is essential to the effectiveness of digital information processing (Stair & Reynolds, 2 3, pp. 6 ). The fourth storage device is the CD ROM. The third storage device is RAM. Hand-entered notations are difficult to read. Data that are used on a temporary basis (such as a Web page; an application in use; or a document being prepared or edited) are stored in RAM, as are the essential instructions for the functioning of the CPU. A faster clock speed determines (in theory) how many actions the CPU can complete in a given time. 3, 6 ).
