Data Input and Output
The purpose of this paper is to discuss methods of data input and output, various computer-related storage devices, and the role of specific items in regards to the speed of a computer. First, the paper will cover the best methods of data input for printed questionnaires, telephone surveys, bank checks, retail tags, and long documents along with an explanation of why these methods are best for the related items. Next, methods of data outputs will be discussed along with the best methods of data output for hand held computers, color photographs, resumes, memorandums, statistical reports, and company annual reports. Additionally, this paper will cover different types of storage devices that are optimal for different data storage situations. For example, this paper will look at hard disks, floppy disks, RAM, CD ROMs, tapes, and flash or jump drives and discuss the situations that are appropriate for using the above-mentioned devices. Finally, this paper will conclude with an explanation of the role of RAM, clock speed, data on a hard disk, data on a CD ROM, and data on a floppy disk in determining the speed of a computer.
In information systems, input is the activity of gathering and capturing raw data. Data input can be a manual or automated process. Regardless of the input method, accurate input is critical to achieve the desired output. (Stair and Reynolds, 2006)
There are several common input devices in which to input data. These devices include keyboards, speech recognition, optical scanning, digital cameras or camcorders, and microphones or musical instruments. Additionally, one or sometimes several input devices can be used to perform the same data input tasks. For example, the methods of data input best used for printed questionnaires would be manual keyboard data entry or a scanner. A scanner would be the best choice for maintaining data integrity while the keyboard method would be prone to human error on the part of the data...
