How to use a Rubber in Mobile Phones Name Institution Introduction Mobile phones (also known as cell phones) have been available for a long period of time now (approximately 50 years) (Karim 2010). Regardless of the fact that mobile phones have been in existence for a very long period of time, it is in the recent times that they have become available for many people in the society…
These devices represent one of the most advanced (sophisticated) technologies ever developed by human beings (Karim 2010). Through them people can communicate with each other, surf on the internet, listen to music, watch videos, and play games among other functionalities. The various functionalities of mobile phones are normally enhanced by design and use of a variety of components in their manufacture. In this regard, mobile phones normally consist of several components, and these components are made from a wide variety of materials (Chan 2007). The materials from which mobile phones components are made include plastics, rubber, magnets, paper and metals among others. This paper, therefore, aims at investigating how rubber is currently used in the design and manufacture of mobile phones. The paper also aims at investigating the alternative areas in mobile phone design and construction that rubber can be used. Main parts of mobile phone and their use The main components of mobile phones are: battery, SIM card, circuit board, keyboard, speaker and microphone, antenna, software, and Liquid Crystal Display screen (commonly abbreviated as LCD screen) among others (Mueller 2013). Circuit board Circuit board is amongst the most important components of a mobile phone. ...
The chips on the circuit board can perform numerous calculations (always millions of calculations) in a single second. The circuit board chips’ calculations are normally performed to decompress or compress voice stream (Harris 2006). Other than chips, another component that is available in the mobile phone circuit board is digital signal processor (commonly abbreviated as DSP) (Mueller 2013). This component is designed to perform operations related to manipulation of digital signals at greater speeds in a single second. Another component that is available in mobile phone circuit board is micro-processor. The microprocessor is responsible for three main functions; these functions are stated below: i. Coordination of all the functions of the mobile phone circuit board. ii. Processes commands as well as control signals related to connecting mobile phone to base station (also known as the cell phone tower). iii. Handles as well as coordinates the functions of display and keyboard. (Mueller 2013) Other components that are associated with mobile phone circuit board are ROM (the read only memory) and chips associated with flash memory. These components are responsible for the running and storage of the mobile phone’s operating system and software applications (Mueller 2013). Mobile phone’s speaker and Microphone Other than the circuit board, speakers and microphones are other important components of mobile phones. It is through the speakers as well as the microphones that communications between individuals are made possible (Harris 2006). Mobile phone microphone is responsible for converting the sound signals to electrical signals. The ...

It was faced off by the emergence of other sources of energy such as cheap coal, and fuels derived from crude oil. Today this has changed due to the impacts of global warning caused by carbon emissions released from coal, petrol, diesel, uranium among others, which are facing substantial resistance across the globe (Walker and Jenkins 1997, p.46).
It is for this reason that environment in which humans live should be conserved and protected against these destructive human activities (Mathew & Philip 2011). One way of protecting and conserving environment is through adopting sustainable activities (sustainable ways of doing things).
Nokia had several products under its company and developed the digital switch that evolved into the multifaceted platform that is still the basis for Nokia's infrastructure today. Nokia continued to acquire more companies and added knowledge and different products/ sectors having to do with electronics such as television manufacturers and computer firms.
. In this context, one of the most striking changes in the use of technology in the last year or so has been the explosive growth in the use of wireless networks for Internet and local network access; Telecommunication companies have spent billions of dollars to purchase licenses to operate 3G networks and since then have invested billions more in developing the technology and buying the hardware to build the needed new infrastructure'.
For this particular study marketing concept adopted is of Nigel F. Piercy's Market-Led Strategic Change. Marketing concept may be explained as a philosophy and as in a technological perspective manner. The whole proposal is presented in the perspective of new marketing concept of market led strategic change.
This report traces the path of Nokia's coming into existence and hence reaching heights of success. It evaluates the importance of SWOT analysis in a better understanding of a business domain. Through SWOT, this report analyses Nokia's internationalisation strategies required in identifying the right industry and the right country for investing.
This is a very important tool to any business that has a dream of excellence. It gives a road map to the desired future. The strategy is like a war plan. It gives the events to unfold at various level of operation of the business. This can be explained in laymen terms as an illustration of where the business is trying to get to in the long term.
