2 Computer Science Development, Program, and Technology Essay in desktop and laptop devices; Nowadays we can hardly see people live without either a desktop computer, a laptop, or even a tablet. As we are moving towards a technology-free-world era, our lives revolve around technology and technical devices.
Technology advancement has no doubt successfully eased people’s life. They have made things function more simply and systematically. Imagine an accountant who has piles and piles of paperwork and stores them using the traditional ways? To able access old files, these accountants have to search for many files in their archives for ages. However, with the help of computers, these accountants exist only required to key in their file code; and they can easily retrieve the old files which they required. Hence, the creation of computers in the mid-70s has contributed a lot to society whereby able to simplify the everyday task of everyone.
The term computers define as how a person can perform numerical calculations with the aid of computing mechanical devices. In the mid-70s, the pivotal objective in creating a computer science development is to tackle the future paperless office culture; and thus to make the interaction between people and digital documents easier.
According to Holmquist, the first computer existed created in the Xerox PARC research lab. However, the computers that we are using today have been evolved through many generations. Most of us have not even realized that the first computer – Abacus, existed created in 2400 BC by John Napier. The computers created in the first generation are normally created using vacuum tubes; hence computers in this generation are normally expensive and bulky.
In the second generation, vacuum tubes computers replace by transistors. Computers that create by transistors are smaller and cheaper, and thus they are more energy-efficient. However, computers build with transistors tend to release a lot of heat from the computers. Computers in the third generation existed built with integrated circuits; which then evolved to computers that are built with silicon chips in the fourth generation. In the fifth generation, more and more evolution has been taking place and now it is still continuously developing. Hence, in light of completing the task of this assignment; the product that I would like to choose to enhance is laptop computers.
The laptop computer that I have chosen to make modifications is the Acer Aspire V5 laptop series. The model which I have chosen is Aspire V5-431. The reason I chose this series of laptop computers is that the design of this laptop is nice; and, the laptop also comes with a reasonable price where everyone can afford to purchase.
The motto of the design of this series of laptops is “thin, light and charismatic”. The size of this laptop is 23mm in height, 342mm in width, and 245mm in depth. The weight of this laptop is approximately 2.10kg. According to Acer (2014), the operating system of this laptop is “Linpus Linux”, the processor’s manufacturer is “Intel”; the processor type is “Celeron” with the processor model of 1007U and the processor speed is 1.50GHz. This series of laptops possess a “Dual-core” processor core.
Besides that, this series of laptops possess 2GB of memory which can maximize to 8GB. The memory technology help in this laptop is DDR3 SDRAM. This laptop only has 2 memory slots, and it also possesses a memory card reader. The type of memory cards that can be read by this laptop is MultiMediaCard (MMC) and Secure Digital (SD).
Moreover, the hard drive capacity of this laptop is 500GB with a hard drive interface of “Serial ATA”, and it also has a DVD writer. The screen size of this laptop is 14”, the display screen type is “Active Matrix TFT Color LCD” with HD screen mode and LED backlight technology. The screen resolution is 1366 x 768, Intel is the graphic controller manufacturer, and the graphic controller model is HD graphics. The graphic memory technology which is being used is DDR3 SDRAM.
The network and communication of this laptop are using IEEE 802.11a/b/g/n for wireless LAN standard, Gigabit Ethernet for Ethernet technology, and the Bluetooth standard is 4.0+ HS. The built-in devices for this laptop are a webcam and microphone. This laptop stands also equipped with HDMI interfaces; 3 USB ports (two USB 2.0 ports and one USB 3.0 port), and an Acer converter port. The input devices for this laptop are the touchpad and keyboard. The type of battery used for this laptop is a 4-cell Li-ion battery with a battery capacity of 2500 mAh, and the maximum battery run time is 4 hours.
There are certain features I would like to add to this model; they are a stylus pen, a built-in printer, and a scanner; as well as using fingerprint to log in to the laptop. With these features being installed in this laptop; this laptop will be suitable to be used by all kinds of people. For example, it can bring benefits to businessmen, as they are often required to print and scan important documents. Besides businessmen, even students or all classes of people are also able to benefit from using this laptop. Apart from that, with these features, even all age range of people also can benefit from these features of computer science development.
Nowadays laptops possess touch screens; hence, it is wise to have a stylus pen being installed in this model of laptop. For instance, stylus pens made signing for documents, painting, drawing, and sketching easier. Moreover, for people who used to draw drafts will be easier when using a stylus pen. This is because stylus pens allow us to precisely do drafting. Moreover, businessmen who always travel for business may find it useful; because they can draw at any place and any time. Matulic suggests that this innovation can gain huge public acceptance.
Apart from the stylus pen, another new feature that I propose to add is a built-in printer and scanner. This is because for travel types of businessmen; it will be extremely troublesome for them to search for a print shop in a city with which they are not familiar. Though they are familiar with the city they are traveling to, it is also difficult for them to find a printer shop in the middle of the night. Moreover, it is also easier for them to print urgent documents at any place (Idea Storm, 2014). With the built-in scanner, it is easier for them to scan company documents which they have verified or signed to the recipient. These features can save a lot of their time.
With a lot of scams and fraud cases happening every day, it is wise to use fingerprints to log in to the laptop. With all the booming security issues, also it hope that with the install of fingerprint readers, these security issues could tackle. The sole reason I propose this new feature is because everyone’s fingerprint is unique. No one has the same fingerprint. Hence, except for the owner of the laptop, no one can have access to the laptop.
Most of the time we will only lock our laptop using self-created passwords, however, passwords can hack. It means that locking our laptops using passwords is very vulnerable. Besides that, using biometric password also bring benefit to people who often have trouble remembering their self-created password. Moreover, Heckle, Patrick & Ozok’s study suggest that there is 88 percent of respondents say that using fingerprint to tackle personal security issue is very useful.
The old features of this laptop actually should all maintain. This is because people nowadays always like to bring their portable laptop computers everywhere they go so that they will be able to do their work on the go. Besides that, some analysts suggested that the demand for laptop computers in emerging markets is still booming. According to King, the market share for the demand for laptop computers has jumped approximately as much as 5.1 percent.
The originally built-in features of this laptop – i.e. webcam and microphone, as well as the touchpad will still maintain. For webcams, there are still people who used them to have video conferencing or teleconferencing. Besides that, a microphone also comes in handy for people who are conducting video communication or telecommunication. For example, people who are using Skype to be able to communicate with their opponents will still require both a webcam and microphone. Lack of one of the tools above – i.e. webcam and microphone, will disable their medium of communication.
Besides that, as for the touchpad, the creation of the touchpad is to replace the use of a mouse. Since the laptop is a portable computer, the creation of a touchpad has saved the users a lot of energy in carrying an extra mouse. Moreover, the touchpad can solve ergonomic issues, whereby users will feel more comfortable compared to the use of a mouse in a long-term period. Hence, the originally built-in features – i.e. webcam and microphone, as well as the touchpad should remain.
Moreover, the DVD-writer should not remove it, though it is kind of old school. However, there are still times we require to install computer science development software programs or games through DVD. Indeed Apple did release an iMac with no optical drive, as indicated by Apple’s senior vice president of worldwide marketing – Phil Schiller, in their product release conference in June 2010, by dropping the optical drive able to save more power consumed by the iMac.
However, there are still users who find that without the installation of an optical drive on their laptop will be troublesome, as they cannot install software programs or games or play movies from CD or DVD, instead they need to download them all from the internet. So, what if the users have trouble in receiving the internet conception due to the place they are staying? Hence, I find that there are no more other features that should remove from this laptop computer.
The features or functions of computer science development, that are with this laptop are all serving their purpose in making this laptop computer align with the theme as “portable”. The principles that will adopt in designing this new generation of laptop computers are the technology acceptance model (TAM) and the six philosophies of Steve Jobs.
First of all, what is the technology acceptance model or TAM? TAM is being extended from the theory of reasoned action (TRA). The TRA suggests that the intention of an individual will have an impact in affecting one behavior. TAM is being used to explain the factors that able affect one to use of IT technology. In TAM five elements are being tested; they perceive ease of use (PEOU), perceived usefulness (PU), attitude (AT), intention to use (IU), and external variables (EV).
PEOU is how one perceives that the use of technology is effortless; PU is how one perceives that the use of technology able help them to solve their problem; both PEOU and PU as well as the external variables such as age or gender can influence one’s attitude towards technology. The study conducted by Park & del Pobil, their study confirms that these five elements possess the ability in influencing their acceptance of technology.
As Kuang identified, the key principles for Steve Jobs to design a product are “craft”, “empathy”, “focus”, “impute”, “user-friendliness”, and “simple”. According to Steve Jobs, though no one will ever find out what is inside the laptop, the designer needs to craft the best elements for their consumers. Hence, the designer needs to be empathetic with the end users’ needs, then the designer should focus on making the end users’ needs meet. Impute is the first impression that the end-users gain from the first glance of the product. Therefore, the designer needs to deliver the product professionally to gain positive impute from their potential consumers.
Besides that, the product should design in a way that is user-friendliness. This is because, if the first impression that the end-users gain from the first glance of the product is uncomfortable and complicated. This “perceived” feeling will draw them not to purchase the product because it is not user-friendliness. Despite having the product being designed in a user-friendly way, the product should also design in a way whereby the end-users will feel that it is “simple”. Simplicity is also one of the important elements for the end-users to decide whether they should purchase the product or not.
In short, the key principles that should adopt in designing the new generation computers should possess both the elements from TAM as well as the key principles from Steve Jobs. Though there are plenty of principles that can adapt, I find that both the elements from TAM as well as the key principles from Steve Jobs are very useful in guiding one to design a product which able to gain wider public acceptance.
In summary, as we are moving towards a technology-free-world era, our lives revolve around technology and technical devices. Technology advancement has no doubt successfully eased people’s life. They have made things function in simpler and systematic ways.
To accomplish this assignment, the laptop computer that I have chosen to make modifications is the Acer Aspire V5 laptop series. The model which I have chosen is Aspire V5-431.

With these features being installed in this laptop, this laptop will be suitable to use by all kinds of people. However, I find that the old features that are with these laptop computers should all remain. These old features do serve their purpose in making the laptop computer a whole.
There are two principles which I have adopted in designing this new generation laptop computer. They are the five elements from TAM – i.e. perceived ease of use (PEOU), perceived usefulness (PU), attitude (AT), intention to use (IU), and external variables (EV), and the six principles from Steve Jobs in designing computer science development products.
