Solution
In today's Internet, voice and Video traffic is often sent over TCP (transmission control
protocol)
instead or UDP (user datagram protocol) because:
- Data transfer by TCP is reliable.
' The most rewalls are configured to blOCK UDP traffic. Using TCP for voice and Video traffic
allows the traffic go through the rewalls.
' connections that use voice/video are quite fast and hence prefer TCP as delays due to lost
packets WOUld be fewer.
' TCP's advantages over UDP include the fact that it has congestion control, reliable transport,
and ln-order receipt or segments.
' TCP's congestion control and reliability mechanisms lead to 100% delivery.

In the support of congestion control over the Internet in providing the assurance of the equality between much diverse traffic is a difficult function. The advent of streaming media has offered users with low-latency media content, with higher congestion on the Internet due to stringent bandwidth and latency requirements. Therefore, it is more and more important to resolve the difficulties of increased packet deliver fail reasoned because of congestion and better quality of service for streaming media. In this paper, we propose a review on the congestion control approaches (CCA) for the real-time streaming applications on the Internet. The role of TCP in network congestion control and the characteristics of the original realtime streaming media are discussed. After that, we discuss issues in the media stream and real-time congestion control. The survey will support the understanding of the current congestion mechanism and continue to enhance the expansion of real-time streaming application services.

How can you define the traits below and what are your thoughts on the importance of these traits to leadership today? Touch on all the following traits in your responses: Integrity Ambition Failure Risk Trust Courage Solution Integrity: Integrity is the quality of a person how he/she is being honest and having moral principles. My thoughts about integrity: Integrity is the most important skill of leadership today because with the help of integrity the leader can manger their team and build a trust between the co-members. Ambition: Ambition is the ability of a person to do something or achieve something. My thoughts about Ambition: Leaders have strong ambition skill so that they can achieve success with the help of team members. Ambition implies works and discipline to achieve the targets in an organization. Failure: In simple words, you can say the lack of success or not achieve the success is a failure. My thoughts about Failure: Failure is an important part of life. In fact, the failure is necessary because it teaches to the person how they survive if they don’t achieve the success. Failure as much as it hurts but we learn the greatest lesson from the failure so the failure is a most important trait in today’s leadership. Risk: Risk is the probability that an actual return or outcome on an investment will be positive or negative. In other words, you can say the risk is the potential of gaining or losing some values. My thoughts about Risk: The risk is a leadership quality in today’s life. A leader is a best when he has the ability to take a risk for the business. Trust: Trust is that where someone is depending on something or someone that can be tangible or intangible. My thoughts about Trust: Trust is a leadership quality which helps to leaders for maintaining a relationship between the trustor and a trustee. In leadership, there is no word more important than trust. Courage: Courage is the ability to do the things which are not expected of someone. My thoughts about Courage: Courage is the key to great leadership because if you facing some difficult situation where you need to courage their team members to do some task which is not easy. Leaders have the ability to do courage their team members so they can do the task easily..

frank has klinefelter syndrome (47, XXY)... Frank has Klinefelter syndrome (47, XXY). His mother has normal skin, but his father has anhidrotic ectodermal dysplasia, an X-inked condition where the skin does not contain sweat glands. Frank has patches of normal skin and patches of skin without sweat glands. Complete the sentences. Some answers may be used more than once or not at all. Frank received the mutant chromosome from his. Nondisjunction occurred in his during the meiotic division. Solution Answer Frank recieved the mutant chromosome from his Father Nondisjunction occured in his Father during the First meiotic division. Since, the mutant gene is present on X-chromosome of Father of Frank Frank has also got this disease, therefore, the second chromosome of XXY combination must have been inherited from father. Nondisjunction has occured at Meiosis- 1 Stage, At meiosis -1 chromosomes separate (Not chromatids), therefore, one cell has recieved both chromosomes (XY) Each chromosomes is made up of 2 chromatids. At Meiosis -II chromatids separate. therefore, the sperm from such a cell recieves one chromatids from X and another chromatids from Y and forms XY combination when this sperm with XY fuses with egg having X, there resultant zygote has XXY genotype.

Does law provide liberty? What is law? How does law tend to be perverted. Solution Ans Yes law of land quite often provide liberty. E. G laws and constitution in many countries provide for liberty. Quite often it is part of preamble in constitutions like that of India. Law are rules which are considered appropriate by a society or nation and it is quite often enforced by imposition of penalties. It tend to be perverted because of vested interests of various pressure groups who want to avoid law and/or use it for their own benefit.

How would these mutations influence the sexual development of the fly embryo? Solution SXL gene is the master regulator of sex determination in drosophila so mutation in the Sxl binding sites will leads to mutant female that prevented from making eggs by protein coding lesion in SXL. Such mutations have no effect on sex determination in XY males. Homozygosity of the intersex (ix) gene causes XX flies to develop an intersex phenotype having portions of male and female tissue in the same organ..

What are the major concerns for corporations in developing and retaining expatriate employees, especially managers? 250 words please What are the major concerns for corporations in developing and retaining expatriate employees, especially managers? 250 words please Solution International corporations use expatriates to maintain corporate control and expertise in various global markets as well as to effectively facilitate entry into new markets. With a steady rise in corporate globalization, employees with international experience become a vital asset to any successful corporation. For that reason, Deresky (2013) suggests that the ability to develop a globally-experienced top management team depends largely on the success of expatriates’ assignments, which is all dependent upon the corporation’s ability to manage the transitions for both the expatriate their accompanying family members (p. 300). Consequently, effective human resource management of a company’s global ends not only with the completion of the international assignment, but rather with the successful return of the executive into company headquarters” (Deresky, 2013, p. 300). Specifically, poor expatriate management can threaten a corporation’s performance and capabilities in the international sector. In fact, poor management prioritization or inattention often leads to failed international assignments. For instance, inadequate management planning on the selection of the expatriate for a particular international assignment will likely lead to the premature return their expatriate or the loss of their returned expatriates due to poor repatriation. Chew (2004) suggests that key predictors of expatriate selection success include: technical ability, managerial skills, cultural empathy, adaptability, diplomacy, language ability, positive attitude, emotional stability, maturity and adaptability of family. Because the human resource management problems are typically more complex in these international circumstances, it often leads to failures in international business. Without a doubt, some of the leading problems encountered by both management and expatriates are unclear expectations, learning a new organization, and the under-utilization of overseas experiences (Vilet, 2012). Considering this, returning expatriates are always sought for these positions, because their previous experiences make the transitions easier on both parties; however, one of the challenges with expatriates is the inability to retain the expatriate upon return from the overseas assignment. According to a 2010 survey conducted by Brookfield Global Relocation, 38 percent of expatriate returnees quit within 12 months—a consistent figure for over 30 years (Vilet, 2012). Much of this can be contributed to the challenging nature of these assignments, poor management, or the limitations on career potential. Likely an outdated and underestimated cost today, research has “determined that the cost of losing a single repatriat.

Which factors might account for the specificity of certain viruses for certain bacteria? Solution a virus that infects and replicates within a bacterium is called bacteriophage. factors which account for specificityy of certain viruses for certain bacteria are - their replication stage like , it is in lytic stage or lysogenic stage.; To enter a host cell, bacteriophages attach to specific receptors on the surface of bacteria, including lipopolysaccharides, teichoic acids, proteins, or even flagella. This specificity means a bacteriophage can infect only certain bacteria bearing receptors to which they can bind, which in turn determines the phage\'s host range. Host growth conditions also influence the ability of the phage to attach and invade them. As phage virions do not move independently, they must rely on random encounters with the right receptors when in solution (blood, lymphatic circulation, irrigation, soil water, etc.)..

What basic auditing policy logs attempts to authenticate a user through a domain controller or a local Security Accounts Manager? Solution “Audit Logon Events” are meant for monitoring the logon/logoff events, and are disabled by default. It is required to enable these policies manually. The basic auditing policy are: It aslo depends on system to system. For windows there are category and sub category for auditing . for ex: Account Logon,Account Management,Detailed Tracking,DS Access ect. This further has subcategory. Events to Monitor A perfect event ID to generate a security alert should contain the following attributes: High likelihood that occurrence indicates unauthorized activity Low number of false positives Occurrence should result in an investigative/forensics response Two types of events should be monitored and alerted: Those events in which even a single occurrence indicates unauthorized activity An accumulation of events above an expected and accepted baseline An example of the first event is: If Domain Admins (DAs) are forbidden from logging on to computers that are not domain controllers, a single occurrence of a DA member logging on to an end-user workstation should generate an alert and be investigated. This type of alert is easy to generate by using the Audit Special Logon event 4964 (Special groups have been assigned to a new logon). Other examples of single instance alerts include: If Server A should never connect to Server B, alert when they connect to each other. Alert if a normal end-user account is unexpectedly added to a sensitive security group. If employees in factory location A never work at night, alert when a user logs on at midnight. Alert if an unauthorized service is installed on a domain controller. Investigate if a regular end-user attempts to directly log on to a SQL Server for which they have no clear reason for doing so. If you have no members in your DA group, and someone adds themselves there, check it immediately. An example of the second event is: An aberrant number of failed logons could indicate a password guessing attack. For an enterprise to provide an alert for an unusually high number of failed logons, they must first understand the normal levels of failed logons within their environment prior to a malicious security event. ----------end-----------.

What is a warrant in Toulmin\'s model of a syllogism? A) A legal document making it legal to search private property B) The logic that connects supporting evidence to a claim C) The numerical date on which a claim is based D) A claim based on two or more distinct premises. Solution D) A claim based on two or more distinct premises. Warrant: The warrants parallel the major premise of a syllogism (Clark 86) and explain why the data is sufficient support for the claim The warrant serves as a \"guarantee\" for the argument , demonstrating or defending how the data supports the claim. Warrants may be laws, assumptions, or beliefs . which may or may not be readily accepted by an audience. Warrants may include definitions for key terms, an argument simpler than the argument at hand but which parallels the more complex argument being made, or a representative sample, that is simple and inclusive or that illustrates a special case The Toulmin model, which was created by Stephen Toulmin in 1958, is a model that was initially used to analyze courtroom discourse and arguments. In the present day the Toulmin model is not only used for courtroom arguments but for more complex arguments in general. It is made of six key components, Data, Warrant, Backing, Claim, Qualify, and Rebuttal. The three most important aspects of the six are Claim, Backing, and Warrant. The Claim is the proposition and states what exactly it is the individual is arguing. The Backing consists of all the materials that the arguer uses to convince the audience that their claim can be trusted. The Warrant is the assumption that the audience may share about a claim that can be used to persuade the audience in the direction of the claim. The Warrant often times goes unstated. Syllogism is also a way to analyze arguments, however it differs from the Toulmin model in that is was designed to break down the more simple arguments and doesn’t analyze the argument as critically. Its main components are the Major Premise, Minor Premise, and the Conclusion. The Major Premise is a broad statement that speaks on the topic of your Claim but is not as precise. The Minor Premise speaks on your claim in a less broader sense. The Conclusion is much like the Claim in the Toulmin model, it indicates what you are trying to argue. There are three types of claims, Fact, Value, and Policy. A claim of Fact is based on facts that the audience can see as objectively verifiable. A claim of Value is based on a topic that is more or less desirable; good or bad. A claim of Policy is based on the notion that a certain law or rule should be changed, or that certain policies should be created to solve certain problems. Claim: The claim is the conclusion to be proven.

What are the main methods anthropologists use? Give an example of how urban anthropologists applied these methods to urban environments. 5-8 sentences Solution Anthropologists use both objective,( i.e, scientific) and subjective (interpretive) methods. They also document their work so that other anthropologists can duplicate it. Anthropological research methods include: 1. Cultural Immersion 2. Human Ecology (analysis of how people interact with their environment) 3. linguistic analysis 4. archaeological analysis and 5. Physical Anthropological Research (analysis of human biology) Cultural immersion: anthropologists interact with knowledgeable individuals of a society to record their culture. They also construct genealogies and maps to show how people in communities are related to one another. Human ecology: cultural research is combined with studies of environments. Human ecology examines how people interact with their natural environments. Linguistic Analysis: Language reveals much about a people’s culture. Archaeological Analysis: specialized research methods and tools for the careful excavation and recording of the buried remains of past cultures. Physical Anthropological Research: Paleoanthropologists and forensic anthropologists construct extremely detailed descriptions of people’s lives from only measurements of bones and teeth..

The polarization of the CMB detected in the WMAP data is evidence for which of the following? A. The first stars had enough mass to change lens the light around them, which polarized the light. B. The first stars acted as polarizing lenses as the CMB passed through them. C. The first stars gave off strong enough radiation to ionize most of the hydrogen gas in the universe, which in turn, polarized the light. D. The first stars, themselves, gave off this polarized light. Solution Answer is (c) Long time back ago perhaps 200 million years after big bang, the evolution of universe is started. when first star started shining then it light reionizes thehydrogen. result from WMAP show that re-ionization started too early as redshift z-20. and it is alsofound that re-ionization process was ongoing when redshift z-6that was a billion years after the Big Bang.it has been found that At this late stage in the evolution of the Universe,the density of hydrogen was much lower than atrecombination. Hence, even though hydrogen isfully ionized, only a fraction of the CMB photonsscattered with electrons after this re-ionization. Ascattering percentage somewhere around 10% to20% is the value favored in the latest analysis ofWMAP data. Even though only a fraction of thephotons scatter after re-ionization, this still has adramatic effect on the production of polarizationon large angular scales, of order ten degrees. Onthese scales the polarization produced atdecoupling (z ~ 1100) is minimal because thesescales are much larger than the mean free path atdecoupling. Thus, the signal from re-ionizationdetermines the shape of the power spectrum atlarge scales..

Review 5 Why is that voice and video traffic is often sent over TC.pdf

1. Review 5 : Why is that voice and video traffic is often sent over TCP rather than UDP in today's Internet? ( Hint: The answer we are looking for has nothing to do with TCP's congestion-control mechanism.) Jim Kurose and Keith Ross,”Computer Networking – A Top-Down Approach”, Addison- Wesley, Seventh Edition, 2017. ISBN-13: 978-0-13-359414-0 Solution In today's Internet, voice and Video traffic is often sent over TCP (transmission control protocol) instead or UDP (user datagram protocol) because: - Data transfer by TCP is reliable. ' The most rewalls are configured to blOCK UDP traffic. Using TCP for voice and Video traffic allows the traffic go through the rewalls. ' connections that use voice/video are quite fast and hence prefer TCP as delays due to lost packets WOUld be fewer. ' TCP's advantages over UDP include the fact that it has congestion control, reliable transport, and ln-order receipt or segments. ' TCP's congestion control and reliability mechanisms lead to 100% delivery.
