Computer Communications & Networks - Lab Report Example In order to test connectivity of the Internet connection, ping command is executed from the command prompt of the operating system. The syntax will be ping (space) (destination address), moreover, in order to review hops and delays in accessing the X stream server, the ‘tracert’ command can be executed from the command prompt. The syntax for this command will be tracert (space) (destination address). The ping command utilized Internet Control Message Protocol (ICMP) to check the connectivity of the destination by sending ICMP echo request on periodic basis. Moreover, the ‘tracert’ command demonstrates all the hops and delays that are in the way of that particular destination. Likewise, it is not necessary that only routers are involved in the process of establishing and exchanging information from the required host. The Ethernet is the first device that initiates and constructs a request datagram from the home computer, as it is considered to be the most pop ular Local Area Network technology that is implemented globally (Ethernet. 2007). The connectivity of the Ethernet adapter is established by both wired and wireless networks. However, in terms of wired connectivity, twisted pairs of cable are connected in to the Ethernet RJ45 socket. The other end of the wire is terminated to the router, switch or hub. In this scenario, home user will use a DSL router that will connect the home computer with the Internet Service Provider (ISP). Likewise, the Ethernet construct the datagram consisting of six parameters i.e. destination address, source address, preamble, type, CRC and data. The preamble parameter is responsible for clock synchronization of the data packets from the source and destination. Likewise, the addresses... This report approves that home Internet users do not have DNS configured. ISP is responsible to resolve the URL into IP addresses. In order to do so, the request from the home network will terminate on the ISP Network that will resolve the URL and sends the request to the relevant destination accordingly. After resolving the DNS for the URL, the router checks for the shortest and robust path for processing the quest with the help of routing protocol. Some popular routing protocols include Routing Information Protocol, Open Shortest Path First, Border Gateway Protocol. After identifying the most suitable path for the request, the connection to the X stream server will be established. Encapsulation of User datagram protocol, IP and Ethernet takes place before sending it to the router for resolving DNS query. This essay makes a conclusion that the first section covered mandatory requirements as well issues that occur on physical layer connectivity. Likewise, we have discussed the Ethernet packet header along with its purpose in details. The next discussion was about CSMA/CD, as the request needs space to fulfill the execution. Next we have discussed the ARP command along with the discussion of a MAC address packet. Moreover, in the next section we have discussed the network layer connectivity and router functionality. We have also put some light on routing protocols and their functions. Furthermore, in the last section, DNS query construction is discusses along with socket connections by incorporating HTTP, TCP/IP, UDP and ARP for opening the X stream web page on the home user browser.

Upper and Lower Class Neighborhoods Essay Example | Topics and Well Written Essays - 1000 words

Upper and Lower Class Neighborhoods - Essay Example This gap has contributed to the several social classes that exist in the present communities. Affluent neighborhoods have several differences and similarities from the lower class neighborhoods (Cubbin et.al, 2008). The difference between the upper class neighborhoods and the lower class result due to better facilities, resources, and services. Because of these differences, the gap between the two keeps widening. The upper class lives in secure neighborhoods, and has access to the best facilities and public services. On the contrary, the lower class lacks access to basic public services. The upper class neighborhoods have a markedly high access to recreational areas and parks. The people inhabiting these regions live in luxurious houses and in close proximity are all sorts of recreational places. There are sporting fields and clubs, gymnasiums, saunas, swimming pools and clubs in upper class regions. For example, golf clubs exist in rich suburbs and golf fans are affluent people. In addition, the rich enjoy frequent visits to parks and gardens and get an opportunity to relax and focus on nature and themselves. On the other hand, the lower class lacks access to such luxurious recreational facilities and parks. These are not available in their neighborhoods and even if they were, it would be too costly to access them. Their income does not allow them to stretch to these recreational facilities. Recreational facilities available in the lower class neighborhoods are small, overcrowded and do not meet the standards of the rich. There exists a concern on the huge differenc e between the school programs in the upper class regions and the lower class neighborhoods. Children born to the affluent enjoy an inclusive and all round education system. In their neighborhoods, schools offer the best as long as their parents can pay. In the upper class neighborhoods, the expected teacher student ratios exist. The school program is usually more accommodating and students receive considerable attention from their teachers. Integrated into the system are recreational subjects that diversify the options available to the affluent students. These schools have the capacity and resources required to nurture the young minds to become reliable independent individuals. These students enjoy quality education. On the other hand, school programs in the lower class regions do not meet the international education standards. There are too many students and fewer teachers. These schools lack adequate facilities that would enable the children to have access to quality education. Ch ildren sent to these schools have to struggle to excel. In the upper class neighborhoods, children have access to equipped local and international libraries. These libraries expose the children to a broad variety of reading materials. Children in these regions can do their research without much strain. On the other hand, it is saddening to realize that children in the lower class neighborhoods lack access to reading material. There are fewer libraries, which apparently do meet quality standards, and the reading material available is not diverse to address the varying needs of the students. In affluent neighborhoods, there are luxurious and classy restaurants where the rich have access to exotic, modern, and traditional dishes and a wide variety of drinks. In these restaurants, prices of food and drinks only favor the rich. These restaurants practice the most current code

On book ( ideas and opinions) by Albert einstein Essay

On book ( ideas and opinions) by Albert einstein - Essay Example Religion is the endeavor of mankind to be thoroughly and clearly conscious of religious values and goals and expand their influence (Einstein 46). There has been an argument over the last century that conflict between knowledge and belief cannot be reconciled. Belief that does not depend on knowledge should be opposed. The school has played a significant role in providing knowledge to open ones way of thinking. Through clear thinking and understanding, we can be able to support convictions. Science teaches us how facts relate to each other or how they condition one another. One should use knowledge in the most complete and transparent approach to achieve goals of human aspirations. Intelligent thoughts play a role in the formulation of goals and moral judgments. It makes interrelation of ends means clear thus leading to fundamental and ultimate ends. Religion plays an extremely vital role in making clear the essential ends and valuations and setting them in the emotional life of a person. Authority of fundamental ends exists as powerful traditions in a healthy society. They come into existence through revelation via the medium of powerful personalities (Einstein 49). The Jewish-Christian religious tradition gives us the principles for ones judgments and aspirations. The tradition gives a firm basis of ones valuations and aspirations. Unfortunately, we can only get it inadequately with ones weak powers. The function of education is to promote a young person develop with fundament principles of science and religion. This will help them look for substance and not the form (Einstein 51). When we compare the above principles with life and spirit of ones times, we realize that we civilized are in danger. This has arises since the rulers are the ones striving to crush the spirit of humanity. Oppression of individuals, nationalism, and intolerance are the one that threaten to choke the cherished traditions (Einstein

A Supra-National Constitution Assignment Example | Topics and Well Written Essays - 1750 words

A Supra-National Constitution - Assignment Example The concept of supremacy of EC law is directly related to the principle of direct effect, direct applicability, and self-execution. The first is pertinent to implementation while the others are to enforcement. It would certainly be impossible to achieve the objective of the Community if its laws cannot be implemented consistently among its members. In traditional international law, the determination of whether a certain provision is directly effective is decided by domestic law. It is also a domestic law that will determine what are the conditions under which such effectiveness applies. This traditional mechanism was short-circuited by the European Community due to its supra-national status and evolved the Community into a legal order sui generis. The principle of supremacy is implied in the very creation of the Community, this is the gist of several decisions of the European court justifying compliance with Community law. Its articulation was necessary for the enforcement of Community law through national authorities and courts. The determination of supremacy, direct effectiveness, direct applicability and self-execution of the provisions of Community law is done under the procedures and precepts of Community law. These doctrines are actually described as constitutionalizing; implementing supra-national effect of the treaty in its member states. As stated in Les Verts, â€Å"The EEC is a Community based on the rule of law, inasmuch as neither its Member States nor its institutions can avoid a review of the question whether the measures adopted by them are in conformity with the basic constitutional charter, the Treaty.†

DELACROIX Essay Example | Topics and Well Written Essays - 500 words

DELACROIX - Essay Example h envoy’s delegation would stay in the North Africa for six months, spending most of the time in the city of Tangier1.Travelling around Algeria and Morocco (after France conquered the former) with the diplomatic mission, the painter carefully â€Å"documented† everything he saw. Capturing the images of exotic lands, Delacroix created numerous sketches, drawings and watercolors. In these images, the painter sought to depict silhouettes, lifestyle, garments and manners. Eventually, impressions that Delacroix got in this trip, served as a rich source of inspiration for his further works. The excerpts from his journal remind of paintings, too. The artist described rather briefly the events that took place during the journey: the mission’s moving through the country, the Jewish wedding, the audience at the emperor’s and others. In addition, there are mentions of exotic Eastern traditions and customs, like that of the Moors described in the note from March 11. While reading his journal, the painting enthusiast would be inevitably enraptured by aesthetics of Eugene Delacroix notes. The genuine artistic nature is clearly seen through the journal notes – the soul of a painter is reflected virtually in every sentence: instead of granting much attention to the events – as ordinary people do – Delacroix was mostly interested in details. It is not the ritual of Jewish wedding celebration that he depicted in his notes, but the surrounding and people. He described clothing, face traits and other details that probably wouldn’t be even me ntioned in a journal of an ordinary person: â€Å"pretty Jewish woman; vest, sleeves, gold and amaranth. She is silhouetted halfway against the door, halfway against the wall.†2 This description of a Jewish woman present at the celebration of the wedding illustrates a peculiar artistic approach – the author doesn’t pamper the reader with exquisitely built complex sentences, this is more similar to operational notes. However, the

Strategic Corporate Finance. All about IPOs Essay

Strategic Corporate Finance. All about IPOs - Essay Example Another option is to raise capital from the public. A corporation is a legal entity separate from the lives of its owners and if conditions are favorable, it can raise capital through an Initial Public Offering (IPO) in the equity market or alternatively through issuing bonds in the debt market. Obviously the public response would depend on the viability of the company, its future prospects and line of business, as well as the reputation and business acumen of its management. Types of IPOs, Advantages & Risks Generally speaking, at the present time there are two options as to how an IPO can be made. The first, as indicated above, is to make a public offering so that all interested investors can read the prospectus and apply for the shares through the stock market. However nowadays things are a little bit more complicated as the IPO is usually conducted by investment banking firms in return for commissions and fees. One of them acts as an underwriter, guaranteeing to take up all share s not applied for. This helps the company raise the required capital regardless of the amount of public response. An underwriting fee is charged as per agreement made with the IPO company. With the large size of corporate entities and the phenomenal sums involved in share flotation, it is not surprising that there could be a number of investment firms involved in the IPO process and they then direct the flow of ownership to popular and moneyed entities so that initial funds to the firm are ensured. However this could lead to lack of diverse ownerships and control problems in later years. The second option in vogue today- and that chosen by Google and Morning Star- is to raise initial capital through an open auction process. As can be imagined, almost anyone interested in bidding can do so by applying for the minimum amount of shares offered in a lot. This can truly diversify ownership as there is no telling who will make a bid for shares (Carter, 2005). It is then up to the registra r to decide who gets the final allotment of shares. However a competitor or an unscrupulous individual or firm may also get hold of a sizeable number of shares this way, so it sometimes makes sense to use the services of investment banks. It could cost a little more to organize road shows, seminars and the like to get people interested, but in the long run more diverse ownership in the hands of the public is guaranteed. It also leads to greater liquidity and the company may not have to resort to stock splits later to dilute values and promote marketability and capitalization (Rao, 2011). A Brief History of Avaya Avaya is a spinoff of Lucent Technologies. Lucent Technologies is itself a spinoff from AT&T.

Prevention of mother to child Hiv transmission Essay

Prevention of mother to child Hiv transmission - Essay Example Quantitative research is the methodical scientific assessment of observable phenomena through computational, mathematical, or statistical methods. For example, the observable phenomena in health and social care may include HIV prevalence in expectant mothers, rate of mother to child HIV transmission, and infant deaths resulting from mother to child HIV transmission. Quantitative uses a systematic approach through actual data collection and analysis rather than making assumptions on describable phenomena. The purpose of the quantitative approach is to develop hypothesis about the observable phenomena. The research technique goes a long way in testing the hypotheses or theories so developed in order to ascertain their veracity or otherwise. In social and nursing care, scholars may use quantitative research to develop hypotheses around mother to child HIV transmission. The testing and proof of such hypothesis can bring significant benefit to the nursing fraternity (Daly, Speedy, & Jacks on 2009, pp. 135-140). Health and social care demands evidence-based practice, which quantitative research provides in hard data. In essence, evidence-based practice (EBP) or Evidence-based medicine (EBM) is the point at which the patient values & preferences, best research evidence, and clinical expertise converge. Evidence-based practice (EBP) involves the prudent utilization of the most reliable contemporary evidence in making critical decisions about the health of patients.
