A Review Of Computer Abilities

1324 words - 5 pages

In an effort to explore the way computers work and interact, we will take a look at the various types of technology available. We start by looking at the best options for data accuracy given specific requirements. Next, we will review what storage devices are available and what uses they have. We will also review the options for quality output and which devices work best for specific types of information. Lastly, we will examine the role of specific hardware in regards to the speed of a computer.Beginning with data accuracy, the best option for data input for a printed questionnaire would be a scanner. The scanner option would allow the information to be entered without any interpretation and prevent errors that may arise from such an interpretation. The best option for data input for a telephone survey would be using automated questions with number prompted responses. This will maintain the integrity of the information as given by the respondent. The scanner is also the best option to maintain data accuracy with bank checks. This is used more often by banks today, not only as a means for accurate input, but also as a means to retrieve the check electronically to review if the information is questionable. The best option for data accuracy on retail tags is the use of bar codes and scanners. The bar code is specific to each item which can then be read by the scanner for tracking purposes. In the case of long documents, we again review the options for data input and settle upon the scanning of the document by the computer as the best option. This will assure accurate input of the data. In all of these options it’s clear that the best method of maintaining data accuracy is to eliminate as much as possible the manual entry of the information.In reviewing storage devices, we find several options available. The hard disk of a computer is usually a storage device that can hold vast amounts of data. The lack of portability makes is cumbersome for transport but it’s easy access is ideal for information that will only be retrieved from that computer. For example, projects that are in process and must be left and returned to at a later time, such as a class paper, or information that is only required when accessing a specific workstation, such as a receptionist’s phone list, is best stored on the hard drive of the computer in use. The floppy disk is another alternative for storing information. The floppy disk is more flexible in terms of transporting the data; however, the storage capacity is small and the technology is quickly becoming obsolete. If you were dealing with an older computer set up on both the input and output ends and transporting smaller amounts of data, such as a presentation for a meeting, the floppy disk could be an option for storage. RAM is another type of storage that is used on a computer. The benefits of RAM are the easy access and ability to change the information as needed without concern that the original data will...
