Wireless Technology - Assignment Example Many cellular phone companies have emerged over the past few decades but few have managed to become household names. The few we acknowledge are namely, AT&T, Verizon, Comcast and ClearWire. All of these use different technologies to offer credible services to their consumers in individual ways they feel fit. These technologies offered, of course, have their pros and cons which will be addressed and compared in this study. All these organizations are established in the U.S but some have consumers across the globe. Their services include, voice transfer, internet services and subscription T.V channels among others. Subscribers may be on a personal or commercial subscription. Personal subscribers pay for their personal needs (in their homes) while commercial subscribers buy and sell these services for profit. They may do so directly or indirectly. This paper will observe the mobile telephone, the premium or pay television and the Internet access, as a means of communication. Telephony i s the construction, development and application that deploys communication and information between two or more parties through the use of wires and the device known as the telephone. Mobile telephony is similar but without the use of ‘wires’. ... AT & T is currently the biggest cellular service provider in the U.S having establishments across twenty two states and enjoys a global market of about 292 million people (AT&T, 2013). This is mainly due to its adaptation of 4G technology which makes it one of, if not the fastest data service provider in the world. ClearWire seems to have the cutting edge when it comes to speed and a wider spectrum in data communication. It uses 4G technology that offers wireless data transfer of up to 2.5 GHZ which is seven times faster than normal cellular service providers, further more it uses (TDD) Time Division Duplex technology which enables it to reuse existing IP network infrastructure which enables it to save on costs of hardware installations (Clearwire Corporation, 2013). It does not congest even in densely populated urban areas due to its deep and wide spectrum. It is also robust and cost effective.\ Verizon and ComCast seem to be at loggerheads when it comes to competition in consumer o utreach, sales and services provider. They also offer the same high speed internet and TV services and are also established in the same city, Philadelphia. Comcast had the primary advantage of having established itself well before Verizon came into the picture and had the monopoly of customers in the whole of Philadelphia. The reason for its temporary fallout was the frustration by consumers of having only one internet service provider and that is where Verizon seizes the opportunity to establish itself. Both however, offer enticing packages, premiums and bonuses on their services to attract more customers and switching between either services does not incur expenditure but you may do so only to find your previous ISP with an even more enticing offer.

Children and Technology - Research Paper Example On taking Matthew’s history, the doctor learnt that Matthew has been in the habit of spending more than 7 hours watching the television and playing video games on the computer for the past 9 years or so. Matthew told, â€Å"I started gaining weight quickly from a very young age, and this, along with my poor academic performance, made me an easy target for bullies. I found it difficult to settle in school and to make friends. Excess playing of fighting games often got me into fights with the bullies of the class, often believing that I would be able to imitate the kung fu moves of my favourite video game character. With such a discouraging environment at school, my only resort was my mum’s computer and the television- something that has been my pastime as far as I can remember.† Matthew’s example shows a more deep-rooted problem. Years of computer and television use have taken their toll on him. This gives rise to the question that is use of technology just ified. Use of technology is common both at homes and schools. The primary element that the schools instil in children through the use of technology is the ability to adapt to change. For this purpose, technology has emerged as a saviour, affecting both the efficiency of pedagogical tools and the individualization of education for the students. However, the varied use of technology in various fields has led to negative impacts too- a topic that is the hotbed of debate for the past few years. The government and the media have strongly been favouring the use of technology in education. Most educationists are of the perspective that learning computer skills at an early age result in better performance in the workplace. However these claims are challenged by skeptics who believe that technology has little contribution towards the enhancement of learning and tends to affect not only the minds but also the bodies of the children. It impacts the imagination of children and initiates a proce ss of degenerative changes in the body. Also, increased use of technology takes time away for physical activities. According to Jane Healy, computers are not an essential part of the lives of young children and have a deleterious effect on the motivation and imaginations of the children. She argues that institutions should wait for children to attain the age of 7 before exposing them to computer use. Despite the benefits technology provides, such as being an interactive interface for learning, use of non-technological ways of learning should be encouraged for young children in schools. Excess use of technology adversely affects the bodies and imaginations of the children; thereby making it a viable solution to discourage the use of technology for children below the age of 7 and use non-technologies based methods to learn basic knowledge such as promoting play, using pedagogical tools to actively engage children in physical activities and mobilizing the media to promote reduced use o f technology in schools for children aged less than 7. In the early years of life, the child is in the process of learning and writing. He is undergoing a series of linguistic and verbal changes with the process of identifying letters, analyzing them and their sounds and then spelling them out being achieved by the age of 7. What would happen if this complex process is disrupted at some point by use of technological means, interfering with the natural order of learning. If a child is exposed to the computers even before they are able to write, it may have significant effects of his health and development. It is seen that gaming is the most popular use of computers for children aged
