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.

The invention of computers has made a huge change in human civilization and society, by changing the way people think. Computers replaced jobs and tedious repetitive thoughts that were done by human originally. People became more and more reliant on computers, and thus, computers became essential to our lives. Computers can manufacture products quickly, and eliminate possible human errors. As technology progresses, new ideas have been brought into computer to make them perform more efficiently. Also, scientists and engineers tend to make things “smaller”, so we can enjoy the benefits from electronic devices anywhere and anytime. Therefore, size and efficiency are two main points for consumers. Desktop computer and laptop computer are representatives for each of these concepts. Although desktops and laptops come from the same origin, they are different in many ways.

In the past few decades, one field of engineering in particular has stood out in terms of development and commercialisation; and that is electronics and computation. In 1965, when Moore’s Law was first established (Gordon E. Moore, 1965: "Cramming more components onto integrated circuits"), it was stated that the number of transistors (an electronic component according to which the processing and memory capabilities of a microchip is measured) would double every 2 years. This prediction held true even when man ushered in the new millennium. We have gone from computers that could perform one calculation in one second to a super-computer (the one at Oak Ridge National Lab) that can perform 1 quadrillion (1015) mathematical calculations per second. Thus, it is only obvious that this field would also have s...
The Von Neumann bottleneck is a limitation on material or data caused by the standard personal computer architecture. Earlier computers were fed programs and data for processing while they were running. Von Neumann created the idea behind the stored program computer, our current standard model. In the Von Neumann architecture, programs and data are detained or held in memory, the processor and memory are separate consequently data moves between the two. In that configuration, latency or dormancy is unavoidable. In recent years, processor speeds have increased considerably. Memory enhancements, in contrast, have mostly been in size or volume. This enhancement gives it the ability to store more data in less space; instead of focusing on transfer rates. As the speeds have increased, the processors now have spent an increasing amount of time idle, waiting for data to be fetched from the memory. All in all, No matter how fast or powerful a...

The input and output sections allow the computer to receive and send data, respectively. Different hardware architectures are required because of the specialized needs of systems and users. One user may need a system to display graphics extremely fast, while another system may have to be optimized for searching a database or conserving battery power in a laptop computer. In addition to the hardware design, the architects must consider what software programs will operate the system.

The computer has progressed in many ways, but the most important improvement is the speed and operating capabilities. It was only around 6 years ago when a 386 DX2 processor was the fastest and most powerful CPU in the market. This processor could do a plethora of small tasks and still not be working to hard. Around 2-3 years ago, the Pentium came out, paving the way for new and faster computers. Intel was the most proficient in this area and came out with a range of processors from 66 MHz-166 Mhz. These processors are also now starting to become obsolete. Todays computers come equipped with 400-600 Mhz processors that can multi-task at an alarming rate. Intel has just started the release phase of it’s new Pentium III-800MHz processor. Glenn Henry is
