True or False? In a proprietary system, a commercial vendor opens their technology to other companies. True False What is network bandwidth? What is a domain name server? Solution 7) Is a proprietary system a commercial vendor opens their technology to other companies Ans- False 8) Ans Network bandwidth is usually expressed in bits per second (bps); modern networks typically have speeds measured in the millions of bits per second (megabits per second, or Mbps) or billions of bits per second (gigabits per second, or Gbps). 9) Ans Domain Name Servers (DNS) are the Internet\'s equivalent of a phone book. They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses. This is necessary because, although domain names are easy for people to remember, computers or machines, access websites based on IP addresses. .

TRUE OR FALSE: 1. N, a nonresident alien individual, was born in Country X and has resided there for the past 40 years. N is the president of a large department store in Country X and is also actively involved in civic, business, social and charitable activities in Country X. Concerned about a recent military coup in Country X, N accepts his opportunity to obtain a green card and he visits the U.S. on May 10,2015 to get his card. Unfortunately, N is killed in an automobile accident in the U.S. on May 15,2015 before his scheduled October 1, 2015 return to Country X. N is a resident decedent for U.S. estate tax purposes. 2 . A (a U.S. citizen), B (an NRA), FlaCo (a Florida Corporation), and FCo (a foreign corporation) each own 1/4 interest in a Florida general partnership which is involved in real estate development. In years 2011 through 2014, the partnership generates a $100,000 operating loss and each partner files its appropriate U.S. income tax returns to record its respective losses. In 2015, the partnership generates effectively connected taxable income (\"ECTI\") of $400,000 and each partner has $100,000 of ECTI allocated to it. Even though both B (an NRA) and FCo (a foreign corporation) have sufficient losses to offset the 2015 ECTI, under the general rule, the partnership must withhold U.S. income tax with respect to their 2015 ECTI. Solution Answer 1 is false as decedent is the non resident alien individual had no tangible property in U.S. Answer 2 is true, any member who is non resident of the state and have income from the state, the partnership must withhold the US income tax which a partner can get the refunded after filing their return. .

True or False Explain Why: 1- SIP and RTP are protocols used to allow communication between users over IP. Solution True SIP( Session Initiation Protocol ) is a communication protocol which is used for voice, video calls and also for instant messaging over the IP networks. It is responsible for establishment and termination of a voice call sessions between the two end points. These session include telephone calls, internet multimedia conference and multimedia distribution. It also provide authentification of caller and callee. It also identifes the number of caller and callee. It is working independent over transport layer protocol. It runs over the TCP(transmission control protocol) and UDP(user datagram protocol). RTP(Real-time transport protocol) is a network protocol which is used to deliver audio and video over Internet protocol. It is used to manage real time transmission of multimedia data over unicast or multicast network. It also monitors data delivery for large multicast networks which allows the receiver to detect if any packet loss. It uses sequence number to detect the packet loss. .

Trace the evolution of the US police system from the \"political\" era to the present. Solution The development of policing in the United States closely followed the development of policing in England. In the early colonies policing took two forms. It was both informal and communal, which is referred to as the Watch, or private for profit policing, which is called The Big Stick. The modern police organizations shared similar characteristics: (1) they were publicly supported and bureaucratic in form; (2) police officers were full-time employees, not community volunteers or case-by-case fee retainers; (3) departments had permanent and fixed rules and procedures, and employment as a police officers was continuous; (4) police departments were accountable to a central governmental authority. Modern police forces in the United States emerged as a response to disorder. What constitutes social and public order depends largely on who is defining those terms, and in the cities of 19th century America they were defined by the mercantile interests, who through taxes and political influence supported the development of bureaucratic policing institutions. These economic interests had a greater interest in social control than crime control. Private and for profit policing was too disorganized and too crime specific in form to fulfill these needs. The emerging commercial elites needed a mechanism to insure a stable and orderly work force, a stable and orderly environment for the conduct of business, and the maintenance of what they referred to as the \"collective good\". These mercantile interests also wanted to divest themselves of the cost of protecting their own enterprises, transferring those costs from the private sector to the state. .

Training and Development Solution The various skills that are necessary for an employee of a large corporation include: All the above factors are of utmost importance for an employee to receive and get benefitted from senstivity training. A large corporation is very likely to operate across different locations having different traditions, culture and values. Thus, an employee needs to be adjustable to different cultures, and learn the business values applicable to each of the culture. A potential leader in a multinational company should be able to overcome the cultural, linguistic and national barriers. Therefore, it is important for the incumbent to be aware of as well as be open to learn other culture. The various trainings that are apt for international staffing are: In Plycentric staffing, the senstivity training and cultural awareness training is not required as the incumbent is already acquainted that culture. However, in ethnocentric staffing, the employee shold be be trained and checked for relevant traits. .

Q0)What are the dye moleclecules doing that makes each specta has a different wavelength Q1) explain how observed color related to absorbed color (hint: color wheel) Q2) Name at least one vaiable that controls absorbance Q3) short paragraph answering why green seater apperas black when shining only erd light on it Q4) ChlorophyII- containing plants appear green. Use color wheel to predit when color of light chlorophyll absorbs? Solution 0) the molecules of different dyes absorb different wavelengths of visible light. They reflect only one particular color and this is the color of the dye. For example: a molecule of green dye absorbs all colors other than green. 1) the observed color is the color that is not absorbed. All materials absorb some wavelengths and the wavelength that is not absorbed is the observed color. 2) wavelength controls absorbance. Fluctuation in wavelength causes different colors to be absorbed. 3) whatever color we see is a part of white light because white light has all colors. When an object is green, it absorbs all colors except green. When red light shines on it, it absorbs red light and does not reflect anything. Hence it appears black. .

Q9: Alvin Goldman and Richard Posner disagree about the value of the blogosphere. Who do you think is right and why? Solution Political Blogosphere:- It draws on the current state of the political blogosphere. by Alvin Goldman, â€œThe Social Epistemology of Blogging.â€ Goldman claims that there are good reasons to be concerned by the rise of the political blog. In particular, he claims that political blogs are replacing mainstream media as sources of political information for significant numbers of the voting public while not replicating epistemically valuable features of the mainstream media.These features include information filtering and the effective discovery anddissemination of political truths. Alvin Goldman said I do not think that the government does bear much responsibility for the crisis. I fear that the responsibility falls almost entirely on the private sector. Firstly, in terms of the widespread nature of the mainstream media, recent years have presented a dramatic decline in the consumption of traditional media formats such as newspapers.The argument for â€˜filtrationâ€™ in terms of democracy aims towards the promotion of knowledge and the avoidance of errors.econdly, the multiple sources claim is again an idealistic notion. This is reinforced by Coady claiming that often multiple sources are not utilised when necessary. Coady and Goldman has identified bloggingâ€™s clear advantages over the mainstream media in terms of its widespread nature, accessibility, filtration system and growing credibility. so i thing both of them are correct .
