Wireless Technology - Essay Example Wireless technologies are becoming commonplace. Millions of individuals and businesses apply to the benefits of wireless technology, to raise the efficiency and productivity of their decisions. That wireless technology benefits businesses and improves their productivity is undeniable. Unfortunately, not all business owners are willing to accept and deploy effective wireless systems in their organizations. Wireless technologies speed up data transmission and are more secure compared with hardware wired mechanisms. The multitude of wireless technology standards makes it possible to find the best solution for each and every worker. The use of wireless technologies is particularly useful for the complex organizations, which comprise numerous departments and are being dispersed over a large territory: in this case, wireless technologies are the only possible way to improving interconnectedness and sharedness of knowledge and data between all levels of the organization’s performance . The current state of technology provides an extensive list of wireless technologies and standards, which facilitate the choice of the best wireless solution. The use of Wi-Fi, HomeRF and Bluetooth favor the implementation of wireless technologies in business and help businesses to meet their data transmission needs. â€Å"Wi-Fi is the most widely used wireless technology at present. It is an IEEE 802.11b wireless standard and can transmit data up to 11 Mbps† (Wells, 2009, p.81). The use of improved Wi-Fi versions is possible, too: for example, WiFi/g and WiFi5 exemplify a relatively new standard of connectivity and can transmit data at almost 54 Mbps (Wells, 2009). Apparently, there is no need to wait until wireless technologies â€Å"settle down†. They have already become an essential ingredient of daily business routine. Undoubtedly, wireless networks can enhance productivity and efficiency within organizations. This is, actually, one of the

Critical Review of Text - Essay Example In the book, the authors provide a compelling look, through a study of the infrastructure’s current vulnerabilities, security gaps, and plans for its protection, of the systems that have been put in place. They also discuss the options that the United States has for the future, all to keep this critical infrastructure, which is vital resources, safe from attacks from both internal and external terrorists (Collins & Baggett, 2009). Various critical infrastructures, including telecommunications, energy, water, distribution of food, and agriculture, are discussed in the book as aspects of the United States’ social, political, and economic systems (Collins & Baggett, 2009). The first five chapters take on giving a condensed view of the American Department of Homeland Security. They also take a broad look at how critical infrastructure within the United States has evolved over the years, reviews important and key legislations made by the US legislature with regards to the in frastructure, directives made by the head of state concerning the infrastructure, and approach the country as a whole takes when assessing its infrastructure. The next five chapters delve into the national infrastructural sectors that the federal government identifies as being of critical importance. Finally, the third part of their book discusses all the hazards to critical infrastructure and their concepts, as well as homeland security’s four pillars. These four pillars include prevention, preparedness, prevention, and recovery (Collins & Baggett, 2009). The book is divided into three main sections with the first section made up of the first five chapters. In this section, the authors deal with what role prevention plays in securing the country’s critical infrastructure. The manner in which the country strives to ensure America is secure and safe is through enhancing the protection of their critical infrastructure to neutralize, deter, prevent, or even mitigate any e fforts by terrorists to exploit or destroy them (Collins & Baggett, 2009). Accordingly, the authors explain that this is done through legislation and directives from the executive branch. In addition, the section also discusses plans put, in place, to protect the country’s infrastructure, the roles played by the private and public sectors in coming up with a national strategy for infrastructure protection, and the manner in which their overall effectiveness is assessed (Collins & Baggett, 2009). The second section of the book sees the authors move further to give a detailed view of the particular critical infrastructure. According to the authors, critical infrastructure can be divided into six overall categories that are distinct but interdependent. Energy systems are the first category discussed with the authors placing hydroelectric power, nuclear reactors, and fossil fuels in the category (Collins & Baggett, 2009). Their second category is the transportation sector that in cludes air transport, rail transport, road transport, and water or marine transport. National icons and facilities are also defined as a category, as is the environment, which includes water infrastructure, food, and agriculture. Electronic transmissions including cyber space is also discussed as a category. Finally, public safety and its importance as a critical infrastr
