Independent Basis Service Set or IBSS Essay Example for Free

Independent Basis Service Set or IBSS Essay Independent Basis Service Set or IBSS is the most basic wireless local area network topology. Sometimes IBSS is also called an Ad Hoc Network. The IBSS is a form of WLAN network topology wherein the set of stations are being recognized by each of the stations. They are connected by the use of a wireless media in a fashion of peer-to-peer. In an Independent Basis Service Set topology, there is a direct communication between the mobile stations. There is a limitation in the communication between a mobile station to the each and other mobile stations because of the limitations in range. Relay functions are not present in an IBSS topology, so all the mobile stations that are connected should be within the range to be able to communicate properly (FallsConnect. com, 2007). Another Wireless LAN topology is the Infrastructure Basic Service Set. The component of the IBSS is termed as an access point (AP). The role of the access point in the Infrastructure BSS is to supply relay functions for the entire basic service set. Communication in the entire BSS is already done in the local points and direct communication is longer occurring. Relay of frames are done by the access points between the mobile stations. The relay function of the access point is effective and efficient in doubling the rage of the Infrastructure Basic Server Set. The access point of the Infrastructure Basic Service Set is also able to offer a bond or a connection that will be linked to the delivery system. The distribution system is also considered as the strength of character of the wireless local area network. The distribution system is the one which provides communication in an access point with other access points. The communication goals are to replace frames for the stations in their basic server set, to promote frames to pursue mobile stations as they move from one basic server set to another basic server set. Swapping over of frames to with a wired network is also a goal of the communication in the distribution system (FallsConnect. com, 2007). IEEE 802. 11 gave distribution system a definition that it may either be wired network similar to the 803. 2 or a special point box wherein interconnection of the access points and supply of required distribution services is given. There is a creation of an extension of the mobility range to an arbitrary range. And this is made possible by the 802. 11 by using the Extended Service Set. Extended Service Set is a set of communication for the basic server set. This is where the access points are able to communicate within themselves. Facilitation of movement from a station to the other station of the basic server set is the goal of the access points’ communication with other access points (US Robotics, 2007). The determination of a traffic done that was forwarded to the basic server set is being identified by the distribution system. The determination and evaluation of the traffic if it should be communicated back to the destination where it came from or if the traffic should be promoted to other access points are some of the roles of the distribution system. Access points have been able to transmit communication to the mobile station. This communication was made possible by the use of distribution system. The communication transmitted will be received immediately by the mobile station. The single MAC Layer is composed of the extended set server. Another composition of the MAC layer network are the mobile stations outside the extended server set. In the single MAC Layer network, all of the work stations are immobile. Network equipments outside the extended server set is not allowed to have mobility unless they are inside the extended server set. These kinds of indirection equipped with the 182. 11 architecture permits other network protocol outside the extended server set to operate properly in the wireless local area network where mobility is available and present (US Robotics, 2007). The data link layer of the Ethernet Local Area Network system was derived from the Medium Access Control protocol. The Media Access Control protocol is the one which summarizes a SDU. Carrier-Sense Multiple Access with Collision Avoidance is the shared wireless media. This is where the MAC Layer offers controlled access. It is commonly like the impact detection access method of the 802. 3 Ethernet Local Area Network. The summary is started with the addition of a 14 byte header before the data and after the data there will also be an addition of a 4 byte (32 bit). The 14 byte header is the Protocol Control Information while the 4 byte is the Cyclic Redundancy Check. Reliable data delivery for the upper layers is being provided by the IEEE 182. 11 MAC Layer. 802. 11 MAC Layer provides security and privacy services to the delivery of the data. Services like authentications offer security together Wireless Equivalent Privacy. The Wireless Equivalent Privacy is the data delivery encryption service for the wireless local area network.

Researching the World of Plastic Surgery Essay -- Beauty Plastic Surge

Researching the World of Plastic Surgery In the creation of our beings, we are blessed, and sometimes cursed with features we, as freethinkers, might not otherwise have chosen for ourselves. Certain circumstances however, may arise on the journey known as life, forcing us to reconstruct these features in an effort to construct normal, healthy, lives. Often, we are compelled to reconstruct these features in an effort to enhance an otherwise normal, healthy life. For the individual unaware of the pros and cons, in regards to the acquisition of cosmetic surgery and reconstructive surgery; I produce this composition in an attempt to inform you, the reader; as well as to expand upon my limited knowledge of this field. In researching the world of â€Å"Plastic Surgery†, we approach a dividing factor. There are two categories into which most operations are labeled. Cosmetic surgeries occur when an individual takes notice of a particular feature on his/her body and makes the decision to alter the imperfection. In humans, it is impossible to find a â€Å"flawless† being. Our bodies, in their own right, are not created equal. A certain degree of asymmetry exists within each of us. Symmetry is not a dominant trait in the human race. Take a picture of your face, photographing each side individually. Place each photo side by side. Notice the difference? Each feature, your eyes, your nose, and even your lips take on their own sense of symmetry, or asymmetry if you will. Reconstructive surgery takes place when an individual is blessed with features that hinder his/her ability to lead a normal, healthy, life. Breast augmentation is one of the most frequently requested cosmetic surgeries. Implants are inserted behind the breast tissue of each breast or behind the â€Å"pectoralis† a major muscle, helping to increase the size of the breast. Silicone implants are made of thick material and filled with either saline or an antibiotic solution during the operation. Women are classically partial to this type of operation. However, in recent years, males have exhibited an interest in cosmetic operations pertaining to the enhancement of the male physique, thus leading to the procurement of â€Å"pectoral implants†. Each sex concludes this course of action for similar reasons. Increased sex appeal, heightened sexual pleasure, as well as a new found sense of confidence, infl... ... some of us are pleased with the features we are blessed with, upon entrance into the world. I am not content with the results, time, and gravity, will eventually afford me. Natural occurrences are, at times, the fault of our deformities; proving detrimental to ones emotional, and physical, well being. In those moments, I approve the operations in search of self-preservation, along with the desire and/or immediate need to correct the aesthetic defaults nature has blessed us with.

Marketing Project Essay

China with its population of over 1.3 billion and the GDP growth rate of 7.7% is obviously a major player in the global market based on its size and growth potential. In recent years, the consumer food service industry in China has significantly grown, driven by the change in consumption patterns of urban Chinese consumers amid the robust Chinese economic growth. A number of Western-style franchise chains are increasingly crossing national boundaries and looking for growth among customers in China. In provinces and regions of better economic development and faster lifestyles, quick service restaurants make up a large share of the total food-service sector. Guangdong province can be chosen as a potentially profitable market where the fast-food market contributes about 90% of the total food service sector’s revenue. Mad Mex, as a new entrant in the quick service restaurant (QSR) industry, is ambitious to penetrate this promising market with the goal to open the first franchise r estaurant in February 2014. Situation analysis: ACMR-IBISWorld (Jan, 2013) estimates that the fast-food restaurant industry in China will generate revenue of $89.60 billion in 2012, up 14.1% from 2011. The pace of urbanization and the higher disposable income urge lifestyle changes and the increase in demand for fast-food. Chinese people have less leisure time to eat in traditional full-service restaurants and prefer to treat themselves in fast-food establishments. Moreover, the rapid development of fast-food service providers and new brands and food styles with improved chain store contribute to the strong growth of the industry in China. The geographic popularity of China’s fast-food restaurants industry is consistent with China’s economic development level. Beijing, Shanghai and Guangdong are three of the most developed provinces and regions in China, which account for about 45% of total industry revenue in 2012 (ACMR-IBISWorld, Jan 2013). These regions witness the relatively well developed fra nchise operations. Porter’s Five Forces Industry Analysis Figure 1: Forces driving industry competition Source: Porter (1980) â€Å"Industry structure has a strong influence in determining the competitive rules of the game as well as the strategies potentially available to the firm.† (Michael E. Porter 1980, P.3) The Porter’s Five Forces Model introduced a concept of structural analysis as a framework for understanding the five basic competitive forces in an industry. These forces, which are shown in Figure 1- new entrants, rivalry among existing competitors, threat of substitute products or services, bargaining power of buyers, and bargaining power of suppliers, reflect that the competition â€Å"goes well beyond the established players† (Porter 1980, pp. 6). Both potential and established players can influence average industry profitability. The threat of potential entrants is balanced by the entry barriers like economic of scale, product differentiation, capital requirements, access to distribution channel, etc. The intensity of rivalry determines industry attractiveness but figures out the extent to which the value created by an industry will be dissipated through competition. Sharon M. Oster (1999) asserts that subsitute products or services play an uneven role in industry dynamics. They can play a modest role in highly competitive industries or during periods of excess production. But subtitutes become significant when demand rapidly increasing or in markets with few competitors. In these cases, the availability of good substitutes influences the profits of the existing firms in a market. Buyer power is varied across markets and constituted by the most important determinants of buyer power in a market, which are the number of buyers and the distribution of their purchase, characteristics of product (for instance, standardization of products increases buyer power). In an industry, powerful suppliers can affect their bargaining power over firms by controlling prices or qualities of supply. Depending on each industry and the particular conditions of the industry, different forces will be more or less prominent in the industry competition. And the collective strength of these forces determines the intensity of competition in the industry and the potential profitability. â€Å"Knowledge of these underlying sources of competition in an industry highlights the critical strengths and weaknesses of the company, animates its positioning in its industry, clarifies the areas where strategic changes may yield the greatest payoff, and highlights the areas where industry trends promise to hold the greatest significance as either opportunities or threats† (Poeter 1980, pp.4). Once understanding these forces and their strategic implications, the company can formulate an effective competitive stratey, which enables it to defend itself from the existing array of competitive forces, affect them in its favour thereby improves the firm’s position in the market. Porter’s Diamond Model Figure 2: Porter’s Diamond Model The theorical framework, which examines the competitive position of a nation and its industries, consists of four determinants: factor conditions, demand conditions, related and supporting industries and firm strategy and rivalry. According to Porter (1998), factor conditions refer to production endowment that players need to compete in an industry. These factors are discriminated into basic factors versus advanced factors, and generalized factors versus specialized factors. A basic factor is passively inherited, for example natural resources and unskilled labour. Meanwhile advanced factors include what nations can create during their industrial growth like capital, infrastructure and highly educated labour forces. The standard for production factors is gradually rising due to the improvement of knowledge, science and technology. A nation can possess competitive advantage in an industry when it is able to create new competitive factor conditions and/or upgrade the needed factors. Demand conditions refer to the nature of home-market demand for an industry’s product or service considering in terms of quantity and quality. The size of the home market, the presence of demanding and sophisticated domestic buyers pressure companies to innovate and upgrade, meet high standards in order to respond to more diverse and higher levels of customer needs. â€Å"The presence of suppliers and related industries within a nation that are internationally competitive provides benefits such as innovation, upgrading, information flow, and shared technology development which create advantages in downstream industries† (Porter 1998). A nation thereby gains competitive advantage in an industry when it has competititve edge in the number of related industries. Another determinant is firm strategy, structure, and rivalry, referring to firms’ organizational structure, management situations and the performance of competitors in domestic market. The presence of intense rivalry in the home base is important, because it is powerful stimilus to creation and persistence of competitive advantage. Two external factors are chance and governments. Chance can discontinue the possibility of some companies to gain competitive position and some lose. Governments have an overarching effect on all the players. In many industries, government is a buyer/ supplier and can influence the competition of the industry by its policies. Government can also affect the relation between an industry and subsitutes through regulations and other means. They play a role in shaping the context and institutional structure surrounding companies and in creating an environment to support companies to gain competitive advantage. SWOT Analysis Internal analysis: Strength: Mad Mex is known as a gourmet restaurant with a healthy, fresh approach to Mexican cuisine. Its philosophy is to offer food servicing in a fast paced environment to create a high volume takeaway business but a unique and high quality product offer that is sufficient to command a premium price point. This concept will bring it the competitive advantage in food service industry relative to other global QSRs in China at present. By remaining true to the founding principles: Fresh and Healthy, Fast and Delicious, Authentic and Exciting, Mad Mex gradually broadens its business with 15 stores opened in just over four years and makes effort to arm itself with a team of business savvy, hands-on, franchisees. Weakness: Established in 2007, Mad Mex is still a baby to global giant fast-food restaurants like Mc Donald’s or KFC with its limited presence in three states of New South Wales, Victoria and Queensland within Australia. It is regarded as a strange brandname to the worldwide food service industry and particularly the Chinese market. External analysis: Opportunities: Chinese consumers are believed to have a positive image of quick service restaurants (QSRs) and good perception of their meal quality and customer services. The average level of consumer satisfaction yet high loyalty of Chinese customers is attracting to Western fast food restaurants franchise to engage their business in this market. According to a study on International Journal of Quality and Reliability Management regarding perceived service quality in the fast food industry in China, â€Å"reliability, recoverability, tangibles, and responsiveness were all significant dimensions of perceived service quality†( Hong Qin, 2010). As the study mentioned, all these positive perception in turn influenced the customer behavioral intentions in the industry. Despite the increasing customer preference for Western-style â€Å"to-go† restaurants in the Chinese market, the QSRs market share accounts for only 9.8 percent of Chinese sales for outside meals (Datamonito r, 2007). This means the unprecedented opportunity for Western restaurant chains to operate in China. Threats: The segmentation of QSRs in China is witnessing a tougher competition between international brands like MacDonald’s and KFC and myriad domestic companies like Yum!Brand and Ajisen. Besides, Asian QSRs are the largest sub-sector in the QSRs in China, in which Chinese cuisine is dominant. It is explained by the fact that Chinese people prefer their tradition rice-based dishes and their price sensitivity when choosing the lower dishes in the Chinese restaurants. Furthermore, for the first time penetrating foreign market, the inability or unwillingness of the company to face dietary and cultural challenges will lead to the failure in the image of Mad Mex in the global market. To succeed in the Chinese market, Western-style QSRs are required to examine Chinese customer behaviours and develop marketing strategies that adapt to the Chinese cultural environment.

Literary Analysis of Hills Like White Elephants by Ernest...

Ernest Hemingways Hills Like White Elephants consists mostly of a dialogue between a pregnant girl and her husband, who would like her to have an abortion. The story defines a two-part theme. The first is a commentary about the way selfishness can corrupt a relationship. The second comments on life and what it means to bear life. This story is developed in a short period of time by Hemingways use of two central elements, character and setting. Though the setting is heavily symbolic, and characters are drawn mostly in dialogue, both are strongly evocative of the theme. Though Hemingways descriptions in Hills like White Elephants are few, he uses every word to create a well defined setting. The story is set in the 1920s, which†¦show more content†¦He doesnt really mean it. He continually pushes her when she doesnt want to talk about it. He really has no respect for her. He corrupts their relationship with his selfishness, which eventually causes it to fall apart (see A Canary for one in Husbands and Wives.) The girl juxtaposes the mans manipulative nature in that she is submissive, willing to please, even though she feels otherwise. She is thinking about the life she carries inside of her, but she wants the love of her husband. She tries to avoid the conversation, so she wont have to deal with what he is making her do. When she does talk, they end up ordering several drinks. She seems to want to drowned out her misery. One of the most character defining places in the story is when she says, And we could have everything and every day we make it more impossible. She wants a full life with her husband but because of his attitude towards the life within her it is impossible. He says they could have everything, but No once they take it away, you can never get it back. She knows they cant have everything. They cant have their child. She values life, but to save her marriage she feels she has to submit to her husband. By the end of the story she doesnt want to see his selfishness anymore and s he tells him to stop talking. She knows deep down that the abortion will cause their marriage to fail, but she doesnt try to stop it.Show MoreRelated Symbolism in Hills Like White Elephants, by Ernest Hemingway1687 Words   |  7 Pagesdifferent literary elements and terms are incorporated into the story by the author.
