Computers and Computer Networks - Essay Example Parameters for this layer are the destination addresses. The Network Layer is associated with routing and directing data to different networks. Likewise, Local area networks, Wide area networks and Metropolitan Area Networks. The Transport layer is associated with check and balance of data packets. It ensures complete delivery of data in terms of files or messages. The Session Layer is associated with maintaining data sessions between different nodes on the network. It also analyzes and prevents collisions between data channels by prioritizing them. The Presentation Layer is associated with presenting the data by converting protocols from data conversion techniques, encryption techniques, binary conversion techniques etc. The Application layer is associated with software including email software, client / server software, FTP software, and much more. Network Components Functionality A simple definition of regenerative repeater is available in network dictionary which states it as â⠂¬Å"a device which regenerates incoming digital signals and then retransmit these signals on an outgoing circuit† The regenerative repeaters are the network devices, installed within the network to regenerate signals that may become weak or unreachable to the destination, due to long distance. These devices are implemented in long distance wired networks for transferring data geographically from one network to the other. As signals, are evolved via network cables, they become weak and attenuated over a certain distance within the same network, resulting in unreachable signals to the destination. This is where regenerative repeaters are useful as they regenerate signals received on their ports and sends the regenerated signals to all the other ports connected on the other end. Moreover, regenerative repeaters do not maintain a database as compare to Ethernet switches and operates on Physical Layer of the OSI model. Furthermore, regenerative repeaters are not compatible for rege nerating signals via two different networks. For instance, the regeneration of signals between a token ring network and Ethernet network is not supported. For example, there are two network locations, where the distance between the two is above 100 meters, repeaters are required to synchronize uninterruptible transmission of data from one network to the other. Otherwise, the attenuation may disturb the digital signals and may not reach the distance, which is above 100 meters. A simplest of definition for a network device known as bridge is as follows â€Å"Local Bridge is a bridge that directly interconnects networks in the same geographical area† (Local Bridge. 2007). Bridge has capabilities to develop network segments. The segments are developed to eliminate unnecessary broadcasting from some workstations or a department on the network. Consequently, the performance of the network will be efficient as bridges can segregate workstation from the network. As these devices oper ate on data link layer of the OSI model, it is implemented to amplify distance between network segments, allowing room for more workstations, to be attached within the same network. Moreover, the segregation of affected workstations from the network, eliminates network congestions and traffic choking. Bridges do not deal with the information available in the higher levels of the

REFLECTIVE PROFESSIONAL ENQUIRY 1 PROJECT - Essay Example Thus they are faced with a responsibility of challenging the disadvantage and the inequality. The oppressive and discriminatory practices faced by the guidance practitioners are in the main social divisions of the race, class, gender, age and also sexual discrimination. (Ali and Graham 1996) In the guidance and counselling practice the practitioners face some barriers and challenges because of an individual’s mental or physical ability. People with various disabilities need some special care and also facilities so that they can be able to work effectively and produce the needed results. In the anti oppressive approach the special provisions for the people with disabilities are put into consideration. This would allow these people to work side by side with the other people who do not have any form of disabilities. (The Disability Rights Commission) The guidance and counselling practitioners discriminate their service receivers on the basis of their physical or even mental disabilities. In the organizations there should be more diverse avenues which should be encouraged so that to encompass all the people including those who have any form of disabilities. On the other hand the society and the practitioners in the guidance and counselling practice are supposed to challenge the way the wants of those who are dominant in the society influence the chances of those with different abilities. (Argyle 1983) In the field of guidance and counselling people who posses various forms of abilities or those with disabilities suffer multiple challenges to the achievement of their human rights. Disability makes it even less likely that the practitioners treat their clients fairly especially those who are not economically independent. The disabled individuals in both the practicing organizations and the society at large are more at risk from abuse and exploitation. For instance in many parts of the world the

Occupational Health and Safety - Essay Example Employees are also required to inspect hoses for leaks at every start of each shift. Further, hoses of oxygen and fuel gas, when taped together, should not exceed one-third of the entire length of the hose (osha.gov, 1996). Grease and oil are also potential hazards and OSHA requires that oxygen cylinders be kept away from grease or oil. Greasy clothes and oily surfaces should be kept away from getting in contact with oxygen cylinders, hoses or any other parts of the valves and regulators (osha.gov, 1996). The scenario showed that the cylinders were lying on the floor and were all stored together in the area. This poses a tripping hazard and greater tendency for the cylinders to roll and bump on each other. The smell of the room being similar to a nail-polish remover suggests that there is a leak in the acetylene cylinder. This suggests that the employee was not able to check the cylinders or the hoses for leakage. Further, the welder, not recognizing the smell is in a very dangerous situation because of the high flammability of acetylene. His activity of chipping the welding slag with the torch tip is high risk of creating sparks that can ignite the room and cause an explosion. With him wearing greasy gloves puts him at even greater risk because the material will immediately catch fire since he was already using the welding slag. The scenario given suggests a very unsafe working condition. It is then very important that employees in construction sites, in this case, those involved in welding and cutting, must be aware of the guidelines set by OSHA to be able to prevent any accidents that may occur in the work

By drawing on examples examine the impact of social networking sites Essay - 1

By drawing on examples examine the impact of social networking sites on society - Essay Example Trends and statistics suggest that the sector has not only brought about significant transformation in the manner in which people interact but has also has acted as a major stimulus for global business (Gatautis, 2008). From social issues to political agendas and corporate strategies, all aspects of society are embraced and catered to by social networking sites. These sites offer a platform to the users to exchange their ideas, anonymously or publicize their views and announce it to the world. It is this flexibility offered by the SNS that makes it the most sought after internet trend in contemporary times. The term social networking is often used interchangeably with other terms such as internet social networking, social web sites, or social networking services; although all of them convey the same meaning. According to Richter et al., (2009) Internet social networking can be defined as "the phenomenon of social networking on the internet". While Kim et al, (2010) define social web sites as "those web sites which make it possible for people to form online communities and share user-created contents". The social networking sites have caused significant impact in various spheres of an individual’s everyday life including the social, political as well as economical. Some of which are discussed below. The probable impact of social networking as a phenomenon on the society can be perceived and gauged in more ways than one. For instance, social networking sites such as Facebook offers users an opportunity to create common interest groups and help them exchange their ideas and present their views in a group of likeminded individuals, thus empowering them to voice their opinions, say for instance, against social injustice or in favor of a social cause. The strength of collective action is magnified by sharing and exchanging of ideas through common groups and helps bring about

The Effects of Social Networks on Firm Performance Research Paper

The Effects of Social Networks on Firm Performance - Research Paper Example The paper tells that in the field of product development the inter organization networks can be very effective for the joint discussion about the product. Many new and small firms have lack of resources for the development, mainly due to inexperience and a lack of goodwill. Thus as a way of competing and grabbing a foothold in such a scenario involves bootstrapping, which involves activities for securing funds and resources. By using social networks such companies can gather finances, by building up strong ties in the initial stages and later on weak ties as they grow big. CEO’s of different firms have been known to have taken advice from outside through social networking. In this way they seek to get an outside opinion and an altogether different perspective regarding certain strategic issues. These enhance the performance of the firms. Another important aspect which is emerging slowly is the concept of a local social capital where an individual who values more of his local c ontacts, even though he has global contacts. This is relevant mainly in case of local entrepreneurs. Thus according to scientists, people with more and better social capital will be able to realize their goals. Ranging from contracts to building goodwill and securing finances, social capital is the priority in all types of endeavors around the globe. Social ties have been found to regulate exchanges through an informal and interpersonal way and they help to push back the limitations of a weak infrastructure, especially in the case of a financial crisis. (Sheng et al, 2011, p. 1). The study is to provide several facts and discussions in relation to social networks and social capital and their effect on firm performance based on the following

Religious Teachings and Business Ethics Essay Example | Topics and Well Written Essays - 3000 words

Religious Teachings and Business Ethics - Essay Example The Utilitarian approach holds to the idea that societies should strive for the best for the most people. Jeremy Bentham eighteenth-century philosopher wrote, "The greatest happiness of the greatest number is the foundation of morals and legislation" (Fisher & Lovell 2003, p. 95). The writer/philosopher John Stuart Mills also wrote extensively on Utilitarianism (Daft 2005). Individualism is viewed as the essentially opposite of Utilitarianism. The Individual approach maintains that right moral choices lead to what is in the best long-term interest of the individual. German economist and sociologist Max Weber's influential essays on capitalism emphasized individual efforts and the accumulation of personal wealth (The Free Encyclopaedia 2007). The Moral Right approach values fundamental human rights and identifies six moral subcategories; free consent, right to privacy, right to freedom, of conscious, right to free speech, right to due process and the right to life and safety (Daft 200 5). Finally, the Justice approach promotes the idea of moral decision making and is based on standards of equity, fairness, and impartiality. Daft identifies three distinct forms of justice(2007). Distributive justice governs the right of people to be treated fairly without discrimination based on arbitrary characteristics. Procedural justice proscribes that rules should be applied consistently and compensatory justice argues that people should be compensated for injury and loss (Daft 2007). Certainly, all four of these perspectives can be identified in most major world religions. In order to set a proper stage for the discussion of religion and its place in business ethics, it is important to provide an overview of the historical influences on the matter. One of the first moral codes to impact mankind stemmed from the religious society of Judaism. In the books of the Bible, there are plentiful references as to how the faithful should conduct themselves in relation to their neighbors, family, and friends. The figures in the Old and New Testaments of Bible; Solomon, David, Moses, and Jesus of Nazareth; were most certainly well known for their ethical teachings. Important philosophers and ethical teachers can be identified throughout human history.  Ã‚
