Unit 3 Case Project Questions Example

Unit 3 Case Project Questions Example Unit 3 Case Project Questions – Coursework Example Unit 3 Case Project for IPCE Network Upgrade This document examines a case project where a company called IPCEaims to upgrade their network. Part 1 of this document explores whether replacing hubs with switches makes the network faster. It also explores whether the use of routers between each switch will improve performance, as well as other configuration options IPCE may consider. Part 2 of this document explores whether hardware needs for upgrading the networks have been met. This is under the assumption that IPCE has ordered 9 Cisco 2600 routers and 10 Cisco 1900 routers. IPCE is also assumed to grow by 100% over the next five years. Part 3 of this document proposes a VLAN solution for the broadcast domains. This includes router interface details, switch interface details, network address for each network segment and indicates the number of possible hosts per network.Keywords: Local Area Network, Virtual Local Area NetworkUnit 3 Case Project for IPCE Network Upgrade A company call ed IPCE decides to upgrade their LAN configuration from 5 hubs and one router to one that implements 10 switches. The company wants to divide their ten departments into separate entities, with routers between each switch. Therefore, this divides the broadcast domains between the switches (Caballero, 2003). IPCE Company is unsure of how to implement their ideas; thus, they employ Windows Networks for consulting services.Part 1Will Replacing the Hubs with Switches Make the Network Faster? Why or Why Not? If hubs are replaced with switches, the performance of the network segments improves significantly. Frames coming into the network segment are duplicated to all devices ports regardless of whether the host requested them or not, thus, increasing network activity. Hubs share bandwidth between multiple devices connected to its ports such that if many devices are transmitting data, the bandwidth is distributed among the devices. Hubs also use a half-duplex transmission mode (Caballero, 2 003). Switches, on the other hand, can detect the device with which data needs to be transmitted to, thus, minimizing network traffic. The full bandwidth in switches is available to all ports at the same rate. Also, switches use a full duplex transmission mode.Will having a Router between Each Switch Improve Performance? Why or why Not? Performance is improved. This is because the routers share the backlog of having to route network traffic, by perhaps working with a backbone router to produce an efficient routing table.What other options for configuring its network should IPCE consider? IPCE should consider using a hierarchical routing mechanism where routing levels are determined by how the company intends to structure its departments and for future expansion.Part 2 Will the hardware IPCE have ordered meet their needs? If not, what would you suggest? The hardware ordered is not enough. IPCE should order 1 or more Cisco 2600 router. This is to ensure that the initial requirement th at each network segment maintain its broadcast segment is met. Other routers may be used to implement Hierarchical routing.Part 3The assumption here is that internet connection is through router 1, perhaps the IT department. ReferencesCaballero, J. M. (2003).

Roth v. United States Supreme Court Decision

Roth v. United States Supreme Court Decision What is obscenity? This was the question put before the Supreme Court in the case of Roth v. United States in 1957. Its an important decision because if the government can ban something as obscene, then that material falls outside the protection of the First Amendment.   Those who wish to distribute such obscene material will have little  if any, recourse against censorship. Even worse, allegations of obscenity stem almost entirely from religious foundations. This essentially means that religious objections to a specific material can remove basic constitutional protections from that material. Fast Facts: Roth v. United States Case Argued: April 22, 1957Decision Issued:  June 24, 1957Petitioner: Samuel RothRespondent: United StatesKey Question: Did federal or California state obscenity statutes prohibiting the sale or transfer of obscene materials through the mail impinge on freedom of expression as guaranteed by the First Amendment?Majority Decision: Justices Warren, Frankfurter, Burton, Clark, Brennan, and WhittakerDissenting: Justices Black, Douglas, and HarlanRuling: The court ruled that obscenity (as defined by whether an average person, applying contemporary community standards, the dominant theme of the material taken as a whole appeal to prurient interest) was not constitutionally protected speech or press. What Lead to Roth v. United States? When it reached the Supreme Court, this was actually two combined cases: Roth v. United States and Alberts v. California. Samuel Roth (1893-1974) published and sold books, photographs, and magazines in New York, using circulars and advertising matter to solicit sales. He was convicted of mailing obscene circulars and advertising as well as an obscene book in violation of the federal obscenity statute: Every obscene, lewd, lascivious, or filthy book, pamphlet, picture, paper, letter, writing, print, or other publication of an indecent character... is declared to be nonmailable matter... Whoever knowingly deposits for mailing or delivery, anything declared by this section to be nonmailable, or knowingly takes the same from the mails for the purpose of circulating or disposing thereof, or of aiding in the circulation or disposition thereof, shall be fined not more than $5,000 or imprisoned not more than five years, or both. David Alberts ran a mail-order business from Los Angeles. He was convicted under a misdemeanor complaint which charged him with lewdly keeping for sale obscene and indecent books. This charge included writing, composing, and publishing an obscene advertisement of them, in violation of the California Penal Code: Every person who wilfully and lewdly... writes, composes, stereotypes, prints, publishes, sells, distributes, keeps for sale, or exhibits any obscene or indecent writing, paper, or book; or designs, copies, draws, engraves, paints, or otherwise prepares any obscene or indecent picture or print; or molds, cuts, casts, or otherwise makes any obscene or indecent figure... is guilty of a misdemeanor... In both cases, the constitutionality of a criminal obscenity statute was challenged. In Roth, the constitutional question was whether the federal obscenity statute violated the provision of the First Amendment that Congress shall make no law ...abridging the freedom of speech, or of the press ...In Alberts, the constitutional question was whether the obscenity provisions of the California Penal Code invaded the freedoms of speech and press incorporated by the Due Process Clause of the Fourteenth Amendment. The Courts Decision Voting 5 to 4, the Supreme Court decided that obscene material has no protection under the First Amendment. The decision was based on the premise that freedom of expression does not provide absolute protection for every possible utterance of any sort: All ideas having even the slightest redeeming social importance - unorthodox ideas, controversial ideas, even ideas hateful to the prevailing climate of opinion - have the full protection of the guaranties, unless excludable because they encroach upon the limited area of more important interests. But implicit in the history of the First Amendment is the rejection of obscenity as utterly without redeeming social importance. But who decides what is and is not obscene, and how? Who gets to decide what does and does not have redeeming social importance? On what standard is that based on?   Justice Brennan, writing for the majority, suggested a standard for determining what would and would not be obscene: However, sex and obscenity are not synonymous. Obscene material is material which deals with sex in a manner appealing to prurient interest. The portrayal of sex, e. g., in art, literature and scientific works, is not itself sufficient reason to deny material the constitutional protection of freedom of speech and press. ...It is therefore vital that the standards for judging obscenity safeguard the protection of freedom of speech and press for material which does not treat sex in a manner appealing to prurient interest. So, there is no redeeming social importance to any appeal to prurient interests? Prurient is defined as excessive  interest in sexual matters.  This lack of social importance associated with sex is a traditionalist religious and Christian perspective. There are no legitimate secular arguments for such an absolute division.   The early leading standard of obscenity allowed material to be judged merely by the effect of an isolated excerpt upon particularly susceptible persons. Some American courts adopted this standard but later decisions have rejected it. These later courts substituted this test: whether to the average person, applying contemporary community standards, the dominant theme of the material taken as a whole appeal to prurient interest. Since the lower courts in these cases applied the test of whether or not the material appealed to prurient interests, the judgments were affirmed. The Significance of the Decision This decision specifically rejected the test developed in the British case, Regina v. Hicklin. In that case, obscenity is judged by whether or not the tendency of the matter charged as obscenity is to deprave and corrupt those whose minds are open to such immoral influences, and into whose hands a publication of this sort may fall. In contrast, Roth v. United States  based the judgment on community standards rather than the most susceptible. In a community of very conservative Christians, a person could be charged with obscenity for expressing ideas that would be regarded as trivial in another community. Thus, a person might legally sell explicit homosexual material in the city, but be charged with obscenity in a small town. Conservative Christians could argue that the material has no redeeming social value. At the same time, closeted gays could argue the opposite because it helps them imagine what life might be like without homophobic oppression. While these matters were decided over 50 years ago and times certainly have changed, this precedent could still affect current obscenity cases.
