Global Water Crisis - Essay Example It is the only natural resource that is consumed by all the living beings. Its significance is evident from the following quote of the former Secretary General of the United Nations, Kofi Anan who stated, â€Å"No single measure would do more to reduce disease and save lives in the developing world than bringing safe water and adequate sanitation (Water: The Crisis of 21st Century, 2007).† Where water gives life it can also take life if it is contaminated. Millions of people die every year due to diseases caused by contaminated water. In fact to be more precise 80% of diseases in the world are due to contaminated water. 90% of waste water is released without proper treatment and poor quality of water causes approximately 50-100 lacks of deaths every year. Poor water quality leads to the death of one child in every fifteen seconds and 25000 people die every day due to malnutrition (Water: The Crisis of 21st Century, 2007). Thus the importance of clean water becomes self evident . In this paper I intend to discuss the looming crisis caused by water shortage at the global level. I have chosen this topic because its importance for all living beings cannot be ignored. All living beings are dependent on it for their survival and for this reason it must be preserved for our future generations. I intend to highlight the present situation related to water shortage. I also intend to reflect on the consequences and causes of water shortage. For this purpose I have chosen to review the relevant literature to support my argument. Towards the end I will conclude with some suggestions that could prove useful for the preservation of water resources for our future generations. Currently our world is facing serious threat of water shortage in the twenty first century. The Toronto Star (2002) quoted the figures from a report published by the United Nations in which it has been discussed that currently 1.1 billion people have no access to clean drinking water,

Quality of Service of Voice over Internet Protocol for Enterprise Use Essay

Quality of Service of Voice over Internet Protocol for Enterprise Use - Essay Example Unless quality of VoIP reaches quality level suitable as an enterprise product, the demand for VOIP will not be fully realized. Developments in VoIP have been able to establish not only as a communication option but as a valuable e-service as well. However, there remains to be key issues that are critical in its adoption into companies or as an enterprise. The main issue is regarding its cost and the quality of services (Biddlecombe, 2005). In 2004, the telecommunications industry saw the launch of mass-market VoIP services that followed the traditional interface models of Plain Old Telephone System (POTS) and by 2005, free services began their entry to the market (Dean, 2003). Among the first one to offer services for free ware Skype which remains to be a significant market leader today. Following the success of Skype other online services began to include VoIP as part of their interface and retooled products as seen in the launch of Microsoft's Window Messenger Live, Yahoo's Yahoo Messenger with Voice and Google's Google Talk among others. However, the greatest potential for VoIP use is in corporate applications. The main benefit is in the communication and networking capacity it can provide. The utilization of VoIP operations using it to traffic PSTN calls locally and internationally (Cave & Mason, 2001). IP Multimedia Subsystems (IMS's) have allowed the incorporation of internet technologies into current systems as well facilitated the actual interface of VoIP infrastructure with PSTN and mobile phones ("Voice over IP", 2006). However, most industry analysts believe that the major issue that companies consider in shifting an IP communications system is its ability to suit the operations and needs of the company (Dean, 2003). It is easy to understand this concern because VoIP adaptation costs a significant amount of capital and maintenance. The service desired is one that does not only exceed traditional PSTN communications but also one that is the most cost effective, easiest to maintain and upgrade. At the moment, there is no standard model for the evaluation of VoIP systems and since it is still being developed, standards of performance are also continually changing (Loyola et al, 2006). The US Federal Communications Commission (FCC) has already set standards for security and communication standards of VoIP service but has yet to be able to cope up with more comprehensive service standards (Hickman, 1998). It is estimated that as the quality of VoIP services increase, the greater its potential to be the premiere communication revolution of the age. VoIP services is not seen just as a revolutionary means of communication but it is the most significant development in the convergence of modern communication technologies. Quality of Service: QoS VoIP quality and reliability has been progressed as networking hardware, software and the speed of internet connections. Paul Travis (2005) estimates that by 2010, VoIP will already adapted by the majority American households, institutions and business. Though the primary consideration according to most studies is the cost of VoIP, analysts believe
