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.

In all of these options it’s clear that the best method of maintaining data accuracy is to eliminate as much...
