Introduction
This paper will take a closer look at data input and also data output considerations. There are many different choices when it comes to data input/output options. While it is good to have many choices, there are usually some considerations that are required to make the best possible decision. The second section of this paper will concentrate on the difference between primary and secondary storage. Lastly, the different roles of computer components and their impact on overall computer speed will be explored.

Data Input considerations
Data input and its accuracy are very important. Without accurate data input, the whole process of processing, massaging and interpreting data may be flawed. However, data comes from a large number of different sources and therefore proper data input treatments and processes must be considered. In the first example, printed questionnaires must be input. As they are in printed form, it is important to ensure that they are clearly printed and that the paper is as clean as possible. The preferred method of inputting this data would be to scan in these pages, and then use a OCR program to convert the input into editable text. OCR stands for "Optical Character Recognition". OCR software "involves computer software designed to translate images of typewritten text (usually captured by a scanner) into machine-editable text, or to translate pictures of characters into a standard encoding scheme representing them in (ASCII or Unicode) (Wikipedia). Another form of data input may be the results of a telephone survey. Since this involves most likely recorded conversations or written surveys filled in by the telephone operator, it may require different methods of input. If the surveys are of a recor...

...also covered. Examples were used to illustrate how different data outputs can be used to convey information. The paper also highlighted the main differences between primary and secondary storage options. A discussion followed on different types of storage devices and what their optimal implementations may look like. Lastly, the role of components in determining the speeds of computer was dissected and explained. Modern day computers are complex and powerful. If Moore's law holds up, then we will be treated to near-super-computer-powerful Personal Computers in the not too distant future.

Data Envelopment Analysis ( Dea ) Essay

- Data Envelopment Analysis (DEA) Data Envelopment Analysis calculates the best-practice frontier for a given sample using piecewise linear programming. It then indicates the relative inefficiency of other units by measuring the distance between these units and the best practice frontier. These models can be input oriented (seeking to minimize inputs while retaining a constant output) or output oriented (seeking to maximize outputs while holding inputs constant). In this instance outputs would be factors indicating general wellbeing, while inputs would be the resources available to the state....   [tags: Output, Input, Input/output, Index]
