Writing Essays on a Laptop or a Desktop
Computer: Does It Matter?
Guangming Ling and Brent Bridgeman
Educational Testing Service
To explore the potential effect of computer type on the Test of English as a Foreign
Language–Internet-Based Test (TOEFL iBT) Writing Test, a sample of 444 international students was used. The students were randomly assigned to either a laptop or a desktop computer to write two TOEFL iBT practice essays in a simulated testing environment, followed by a survey of computer experience. The survey results suggested that the participants had extensive experience using computers, had more experience with laptops than with desktops, and preferred using the laptop computers to the desktop computers. The computer type (laptop or desktop computer) was found to have a negligible effect on essay performance (essay score, essay length, and writing speed). However, other factors, including gender, regional background, daily experience with laptop or desktop computers, preference for a particular pointing device, and previous TOEFL experience, were found to be significantly related to essay performance but did not interact with computer type.
Keywords: computer type effects, desktop, e-rater, essay length, essay score, laptop, writing speed

INTRODUCTION
When large-scale computer-based testing began in the early 1990s, testing centers were equipped with standard desktop computers. At the time, this was the computer type most familiar to students. Testing on what were then relatively rare, laptop computers appeared to be acceptable for multiple-choice questions, but resulted in degraded performance on essay questions (Powers & Potenza, 1996). In the past decade, laptop computers have...

Desktops vs Laptops

...Desktops vs. Laptops You may often hear people say laptops are better to have than desktops. Although they are very convenient and portable, desktop computers are faster, easier to work with, and have more features. What is best for one person may not be best for another person. They both have their advantages and disadvantages, but for each we have to consider whether the good outweigh the bad. We have to take into consideration price, size, speed, and capacity, battery life, and stability. Laptops are usually more expensive than desktops because that are a great deal smaller and still have many of the same components as a desktop. Because of the way they are designed, components have to fit into a small compact space, conserve power, and produce less heat. Repairs and maintenance will cost more because they usually require professional work in order to be fixed properly. The parts are also smaller for laptops, making them more expensive. The most obvious difference between laptops and desktops is size. This is also the main reason a person may choose to get a laptop. They are much smaller and lighter, which makes them easier to travel with. You can go anywhere, anytime, and still have access to a computer. You can receive wi-fi, so the internet connection should not be a problem. You are not tied to one particular desk, and you have the freedom to move around with them. They are great for class and work presentations. When you get a desktop home and place it that is...

Computers vs. Laptops

...Desktop Computers vs. Laptop Computers Ryanne Donahue ENG 121 English Composition 1 Prof. Tina Santino April 23, 2012 Desktop Computers vs. Laptop Computers Computers are one of the most popular kinds of electronic devices in the world today. Whether kid or adult, male or female, everyone wants to learn how to operate the computer. People use computers for different purposes such as typing papers, creating websites, browsing the internet, playing games, etc. In fact, many people are still confused about what kind of computer they want to buy. There are two types of computers: laptops and desktops. They are both actually very different in several ways. This paper will compare the size, performance, maintenance, and price of the two. As we all know, a desktop computer is hard to move and is cluttered due to many wires and cables that need to be connected to each. They need to have lots of attachments when using a desktop computer. It is annoying having all those wires and cables when trying to use a computer. The speakers, keyboard, and mouse are all built in on a laptop computer. That makes it hassle free of the wires and cables. Unless they want to acquire a mouse for the laptop, there will not be as many wires. The laptop is also portable, making it easier to move and take when traveling, and does not take up a lot of space. Performances of a laptop computer and desktop computer have great differences. The desktop computer has better components and can handle......

Research

...The world has become very dependent on computers. The king of the block used to be the traditional desktop computer. With the rise of the laptop computer the demand for the once revered desktop computer has declined. This raises the need to investigate the current and future state of the laptop computer and why it is dominating the market. Overall, research will show that the advantages of moving to a laptop computer can far outreach the benefits of the disappearing desktop computer. Laptop versus Desktop Computers Computers are a very important part of our lives both in business and personal use. The decision between laptop and desktop can be a difficult one. Laptop computers provide many advantages over their disappearing predecessor, the traditional desktop computer. Many of today’s manufacturers are focusing on mobile computers because the demand for them is much greater than for the traditional desktops. As this technology advances and becomes quicker and easier to use, the traditional desktop computer is slowly joining other dinosaurs like the record player and 8 track player. The Rise of Laptop Computers Just ten years ago laptop computers served a small group of people in the business world. Their processing power was slow and capabilities were extremely limited compared to the standard desktop computer. The cost for a laptop was far from affordable to the average person. They did have one advantage at the time; mobility. They could be carried almost anywhere;...

Operating Systems

...I have a HP Flyer Laptop PC and I have had it for a few years now. Personally I love it and I think the operating system is great. Reading chapter 8 in the textbook has helped me understand my operating system more and my laptop more as a whole. The operating system that I have on my laptop is Windows 7 Professional. Along with Windows 7 Professional, Service pack 1 is also on the computer. There is a 500 GB hard drive and also 14.7 G of disk space. It was interesting seeing that the processor installed on the laptop is called AMD E - 350 Processor 1.60 GHz. I did not think that processors would have unique labelings, I figured they would just have simple names. The RAM amount is 4.00 GB and the computer cannot be updated to the latest version. Reading about the many features of Windows 7 Professional was a surprise because I did not notice all of them until I did some research. Windows 7 Professional has an encrypting file system that enables encrypting of files and folders directly from Windows explorer. Another great feature is that the whole computer or certain files, folders, etc can be backed up on DVDs, CDs, and networks along. The computer, files, folders, etc can also be restored from the DVDs, CDs, and networks. There is also a memory support feature that allows 192 GB of physical memory to be supported. Along with the other features, Windows 7 Professional has location aware printing. This means that your computer can search for near printers and......

Pc vs Mac

...18 October 2011 PC vs. Mac: The Real Truth As computers have developed through the last few decades there has been a war between the companies arguing whose computer is best. As more companies developed the birth of Macintosh arose. What made the difference was the makeup of their operating systems at the time. As time went by the difference became more descriptive and detailed. Today the fighting between computer companies never ends, but I am here to prove once and for all that the specifications, availability, and the price variation make PC superior to Mac. One important aspect that makes PC more sophisticated than Mac is the specifications. The fastest desktop PC has a six core processor running at 3.46 GHz without overclocking. Also with their new turbo boost mode that was recently developed it tops out at 3.73 GHz. Mac’s on the other hand have to use two six core processors running at 2.93 Ghz to try and keep up with speeds of desktop PC’s. Pc’s are faster at desktop but also laptop as well. The speed of PC was just proved greater than it opponent Mac which makes PC a greater choice. The availability of a computer is also important when fighting Mac. Another key component when arguing about PC verse Mac is the availability of the product. Today most people will build their own Desktop PC and sometime even laptops. People do this because of the available customization they can achieve and, also it is cheaper this way. They can customize their PC with lights,......

10 Fundamental Differences Between Linux and Windows

...(and elite, to many) group, you will never lay eyes on code making up the Windows operating system. You can look at this from both sides of the fence. Some say giving the public access to the code opens the operating system (and the software that runs on top of it) to malicious developers who will take advantage of any weakness they find. Others say that having full access to the code helps bring about faster improvements and bug fixes to keep those malicious developers from being able to bring the system down. I have, on occasion, dipped into the code of one Linux application or another, and when all was said and done, was happy with the results. Could I have done that with a closed-source Windows application? No. #2: Licensing freedom vs. licensing restrictions Along with access comes the difference between the licenses. I’m sure that every IT professional could go on and on about licensing of PC software. But let’s just look at the key aspect of the licenses (without getting into legalese). With a Linux GPL-licensed operating system, you are free to modify that software and use and even republish or sell it (so long as you make the code available). Also, with the GPL, you can download a single copy of a Linux distribution (or application) and install it on as many machines as you like. With the Microsoft license, you can do none of the above. You are bound to the number of licenses you purchase, so if you purchase 10 licenses, you can legally install that...

(Graves 2013) states that it is difficult understanding human emotions effect on the buying decision process yet because we humans have very similar neural wiring we tend to make similar mistakes what he calls ‘mind gap’.

Apple vs Microsoft

...MICROSOFT VS MACBOOK INTRODUCTION May 2006 marked a special moment in computer history. Apple introduced the MacBook: the first consumer Apple laptop that runs on an Intel chip. This is significant because Windows users now can truly compare Windows-based laptops to the MacBook family. The speed of the MacBook is on pace with the speed of PC laptops. Windows users have less and less reasons to remain Windows users. Running parallel to the increasing reasons to consider Mac over Windows is the fact that our world has evolved from a desktop world to a laptop world. Laptops are so fast and well-equipped nowadays that they serve the needs of not only consumer users, but also professional users such as graphic designers and high-end Photoshop users. There's now only two groups of users that should even consider buying desktops:1. mega-power users. This includes hardcore gamers, 3d animation users and professional video editors. These guys need the fastest machines available to make their processor-hogging routines running faster and faster.2. super-budget users. You can get a nice desktop for $500 nowadays. nice laptops go for about $1000+.That leaves the rest of us. And that's a large group. Laptops offer a freedom that no desktop (or even an iMac) can offer: Portability. Use the laptop on the couch while watching TV. Use it at your desk to get serious work done. Use it on the deck to enjoy the spring weather. Use it at the coffee shop or library to simply look cool. Plus,......

...Memory protection is necessary because it stops unauthorized programs, which may contain harmful threats, from accessing the computer’s memory. Memory sharing is when multiple programs need to access the same portion of memory. Proper management of memory ensures that this happens without hindering the performance of the system. Relocation involves moving programs between virtual memory and physical memory 2. Compare two common operating systems—Windows 8 and Fedora 20—on the difference in the memory management features. * Full access vs. No access * Linux Fedora 20: Linux has the most significant access to the source code, allowing the users to alter the code that serves as the foundation of the Linux operating system. * Windows 8: Windows 8 allows no users to the code, which is a good idea once you think about it, as some people has used that access to take advantage to make bugs and viruses. * Licensing freedom vs. licensing restrictions * Linux Fedora 20: With a Linux GPL-licensed operating system, you are free to modify that software and use and even republish or sell it.

Many have debated that Pc is better than Mac while others have debated Mac is better than Pc. Only a few have said that it depends on what it’s used for. If only we had more insight to both sides of Mac and Pc. Many people pick a computer based on what they are used for to and don’t find the computer that’s right for them.
