Advantages And Disadvantages Of Networked Medium Information Technology Essay

Advantages And Disadvantages Of Networked Medium Information Technology Essay Bus networks use a common backbone to connect all devices. A single cable, the backbone functions as a shared communication medium that devices attach or tap into with an interface connector. A device wanting to communicate with another device on the network sends a broadcast message onto the wire that all other devices see, but only the intended recipient actually accepts and processes the message. Ring topology: In a ring network, every device has exactly two neighbors for communication purposes. All messages travel through a ring in the same direction. A failure in any cable or device breaks the loop and can take down the entire network. Star topology: Many home networks use the star topology. A star network features a central connection point called a â€Å"hub† that may be a  hub,  switch  or router. Devices typically connect to the hub with Unshielded Twisted Pair (UTP) Ethernet. Compared to the bus topology, a star network generally requires more cable, but a fai lure in any star network cable will only take down one computer’s network access and not the entire LAN. b) Advantages and disadvantages of each medium. Network medium is the physical channel that used for transmission in the network. The types of the medium are: Wire Fiber air Wire: UTP cable is a medium that is composed of pairs of wires.  UTP cable is used in a variety of networks. Each of the eight individual copper wires in UTP cable is covered by an insulating material. In addition, the wires in each pair are twisted around each other. Fiber: Long distance signal transmission. Large Bandwidth, Light Weight, and Small Diameter Long Lengths Easy Installation and Upgrades Non-Conductivity Security Designed for Future Applications Needs Air: Mobility. Elimination of unsightly cables. c) Recommendation for topology and medium to use: Topology: Figure 1.1 : Star topology We select the star topology for this in-house network. Because the star topology is most popular topolog y for in-house network (LAN). Also we can be benefit by using the star topology in a LAN. Benefits: Information can be easily shared allowing for quick and informed decisions to be made, saving time and money. A more productive and competitive environment is achieved through greater teamwork within the organization. Network-based communication such as email is considerably cheaper than using the phone or fax and sharing resources such as printers gives more efficient use of equipment at lower costs. Standard versions of procedures and directories can be made accessible to everyone. IT administration can be centralised. Data can be backed-up from a single point on a scheduled basis ensuring consistency. Medium: Figure1.2: WI-FI network We select the WI-FI for this in-house network. Because Mobility. Elimination of unsightly cables. Problem Identification: Task 2 – 10 Marks Investigate the Internet connection requirements for the Fire Department. a) Describe the Internet servic es that may be required. b) Explain the connection speeds that are suitable for these requirements. c) Find examples of Internet Service Providers (ISPs) that can meet these requirements in your country. d) Make a recommendation to use one ISP based upon the services offered and price charged.

Sexual Orientation in Organizational Communications Essay

Sexual Orientation in Organizational Communications - Essay Example Despite serious social movement of the LGBT (Lesbian, Gay, Bisexual, and Transgender) community in recent decades, the minority of people are still fighting for equality. And in this fight corporations are extremely important in terms of the LGBT community acknowledgment because they can provide their employees with decent support and do it more profoundly than country and local authorities (LGTB Manual, 2010). There are few companies that are able to risk their reputation, unless their reputation is so immaculate, and make such a contradictory issue as accepting non-traditional sexual orientation of the employees in company`s policy. Such companies receive unnecessary attention and their public relations sphere is suffering. In such a situation Disney, the company specializing in the children`s entertainment content and supporting homosexuality acknowledgment at working places looks absolutely extraordinary (Tully, 2013).However, Disney was and remains such company, and despite its worldwide success it is being accused of promoting immoral values to the future generation. Reasonably it raises a lot of questions regarding the place of homosexual propaganda in a corporate world and especially in children`s content. However, Disney manages to communicate to the world that their policy is grounded on higher values such as equality, acceptance, and diversity, and sticking to these goals can ser ve as the most important factor. Moreover, Disney`s internal policy of visibility is coherent with its external representation which proves that the company has a well-elaborated policy and know what image to create in consumers` perception. Disney was established in 1923 by two brothers, Walter and Roy Disney as a small cartoon studio in California. Today this multinational corporation is one of the biggest Hollywood studios and is the owner of 11 theme parks around the planet, two aqua parks, and several broadcasting companies. The company`s main product was  children`s animation movies before it launched its radio, films, and entertainment facilities (Corporate History, 2008).

Philosophy of Economic Thought - Essay Example In spite of the fact that many of them had already dabbled into the interpretation of Keynes’s point of view, two of those whose analysis are worthy of being examined are Paul Davidson and Axel Leijonhufvud. The critics of Keynes believe that the main contributions made by Keynesians and post-Keynes theorists to economical theory are all negative, particularly as they seems to attack the conventional way of interpreting situations. For many of this critics, the saddest dimension that there is to it is that Keynes theorists, besides dumping the traditional ways of perceiving situations, is that they do not offer an alternative through which the ‘anguish’ experienced by people in their daily life can be reduced. Paul Davidson does not agree at all with all what this critics opine. He believes that such positions are assumed by classical economists who find it almost impossible to align themselves with the change that is offered by Keynes (Davidson1994). The approach adopted by Davidson shows how Keynes’s General Theory is relevant to people in the globalised world in which we now live. (This actually is to annul the assumption by some individuals that Keynes’s General Theory is no longer relevant in this time and age). ... Leijonhufvud believes that the stand of Keynesian economists was overhyped. Unlike the paradise that some had conceived from it, the truth is that Keynes’s General Theory has many loopholes which were yet to be revealed. As with many other theories, whose foundations were not solidly founded, a wave of strong desire for change will sweep it into nonexistence. Leijonhufvud was one of the first few economists to present the new viewpoint which opines that typical Keynesian theory needed a major re-education or a new drive to ensure that they know what they should really stand for. Leijonhufvud, for example, posits that the theory of markets fundamental IS-LM was lethally defective and should be substituted. To back up his point, he cites Keynesian’s reliance on inflexible wages. Patinkin (1948) proves that there are always some supposed levels of prices and wages which are low enough to engender a full employment level of cumulative demand. This is clearly in antagonism t o the Keynesian position that insists unintended unemployment can be link to the prevention of wage or price rate from dropping to a hypothetical or supposed level. It is quite ironic that Keynes who lived a huge part of his life as an open market analyst is the one who has developed theories whose major application is in closed economies (Keynes 1936). One of the points that Keynes may have wanted to prove is that even if one is inattentive to international trade and its impediments, a closed economy did not hold any regular market apparatus that assured a full-employment symmetry (Keynes 1936 p. 120). Davidson (1994) also has this to say: Any deliberate policy that aims to make a nation’s industries more
