Detailed specification and costs of a mobile computing device and a desktop machine - Essay Example Computers do many different things by using the same hardware (all the solid stuff in and on the case) but using different software, programs which tell the computer what to do and how to do it. Computers come in three basic types: desktop, laptop and palmtop. The desktop which usually consists of a box, a screen, a mouse and a keyboard can usually do more than the others. The laptop, sometimes called a notebook or subnotebook PC. These machines are all-in-one packages with the computer, keyboard, mouse and display screen all together. They are generally not as powerful as a desktop and the desktop costs less for the same features, because the portability is expensive. Palmtops are really small subnotebooks, not much bigger than your hand. However, to qualify as a palmtop computer it has to have all the same attributes as the others: it must run different programs which you can buy and install, it must have an input device, a processing unit and the ability to output to a device. A PDA is a Personal Digital Assistant. It has many of the functions of the computers, but very limited capacity and power, partly due to its small size. The high end PDAs include word processing, email, calculating, databases and Internet access. Some come with simplified accounting software as many users need them to make entries into expense accounts. Mapping and GPS is a very popular function on these devices, and a few, called smart phones, have a cell phone, possibly a camera and Bluetooth and edge wireless technology built in. Most newly manufactured PDAs will accept external memory cards to expand their capacity. Most PDAs will connect to your computer in order to synchronize information, such as contact lists, to-do lists, and calendars. They can also move music, photo and video files back and forth between the machines. (Gookin, Dan, 31-44) So let’s look at the components of these devices and exactly what they do.

Article Critique - Essay Example Purpose of the research The research sought to establish the factors from the SCT standpoint that influence the consumption behaviour of fruits and vegetables among the adolescents in the low-income bracket of the black Americans in the lower Mississippi Delta region. Personal, environmental as well as behavioural factors have been investigated in the study to establish the extent to which they influence the consumption patterns of fruits and vegetables by the targeted adolescents. Method of the research This qualitative research used the focus group methodology to collect data from the participants. 42 adolescents between the ages of 10 and 13 years were involved in the focus groups which were divided equally into six. 21 female and 21 male adolescents were involved in this study. The advantage of this method is that it enabled the researcher to get personal opinions from the participants about the factors that influenced their consumption behaviour and patterns of fruits and vegeta bles. Results of the research The results of the research have been divided into three main categories of the Social Cognitive Theory which include behavioural, personal and environmental factors. ... Personal factors such as taste played a major role in influencing the consumption behaviour of fruits and vegetables among the youths who participated in the survey. There were both negative and positive connotations about the taste of fruits and vegetables. For instance, many youths revealed that they like fruits because of their sweet taste while the taste of vegetables produced more negative reactions. Many youths described the taste of vegetables as â€Å"nasty† and they said that they would rather prefer to eat vegetables that have been prepared with sugar or cheese since these ingredients could improve the taste. The results of the study also revealed that environmental factors have an influence on the consumption behaviour of fruits and vegetables by the youths. The aspect of availability played a major role in influencing the behaviour of youths towards fruits and vegetables. Many participants pointed out that fruits and vegetables were not readily available at their h omes as well as the nearby grocery shops. Some of the youths said they ate fruits and vegetables when they visit their friends’ places. This showed that the youths cannot be able to consume something they cannot readily access and this is seen as a barrier to their consumption behaviour of the fruits and vegetables. Conclusion of the research The purpose of this research was to explore factors that influence the low-income southern black American adolescents' fruit and vegetable consumption patterns with the aim of developing tools that are culturally relevant for intervention and measurement of behaviour among this target group with regards to choice of fruits and
