The network IP addressing scheme for the MD building is designed to ease network management. It have to protect students and employees data as well as any intellectual property that UMUC has on the servers and computers. The IPS with Application Level Gateway Firewall security appliance will be installed to secure the private network from the Internet and provide IPSec VPN connectivity to the main UMUC office. The Intrusion Protection System (IPS) is able to inspect network traffic, examine and filter based on information contained within the data portion of a packet. It help the IT personnel monitor, log, and detect security breaches. It could use to send security breach alerts, terminate security breaches, and terminate or restart processes. The network will use the Ethernet, 24 RJ-45 ports, Power over Ethernet (P0E) switch series because of their high performance. The switches are can support up to 144 gigabit network connections (10/100/1000baseT Ethernet) and one will be installed on each floor in the Server Room. We will write a custom essay sample on Network design or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The switches will be configured with a tagged VLAN (Virtual Local Area Networks) for each subnet. The network will be secured using Active Directory single sign-on and IP addresses centrally managed using DHCP with DHCP relay enabled on the switches to forward DHCP broadcast traffic as unicast transmissions across VLAN boundaries. The switches also will be installed in each office or room which have more than four workstations. The switches will be connected in a partial mesh that ensures no single point of network failure. A Wireless Access Point, 802.n11b/g/n Wireless, 100Base TX Ethernet series will integrate seamlessly into the network with VLAN support and provide 104 Mbps network access speed. Wireless media access will be protected using WPA2 security with AES 256 encryption and authentication using user credentials and 802. 1x integrated into Active Directory via Radius(ACLs applied to the VLAN for security). The servers in server rooms with the Windows Server operating system will be installed for the Active Directory and Microsoft Exchange servers and as dedicated file servers. This hardware includes a RAID 5 fault tolerant, hot swappable disk array that will continue to operate even if one drive in the array fails. Each server is also equipped with a UPS (Uninterruptible Power Supply) that filters power line surges and enables graceful shutdown in the event of a power outage to protect data from corruption. The primary Active Directory domain controller will reside on the first floor and a backup domain controller on the second floor to maintain network access if the primary domain controller fails and share the load. The servers in each lab (six class room computer labs and a student computer lab) with the Windows Server operating system will be installed for the Active Directory and Microsoft Exchange servers and as dedicated file servers to support each special lab need. Each server will have two network interface card (NIC) and could be configuration to be a small network. Each floor will also be equipped with an network printing scanning, copying for Administrative and Instructional networks. The Administrative printers will be in the front of server room each floor. The Instructional printer will be in the front of library and student computer lab. CAT6 UTP (plenum rated where required) will be installed in a star topology because is less expensive and provides higher performance than ring (using Token Ring Protocol) and bus (using RG6 and RG58 coax cable). However the distance from the server room on each floor to the last room is over 300 feet (the Ethernet limit) and a diagonal pull through the ceiling (240 feet length, 95 feet width plus a 30 feet drop). We have to install switches 150 feet from the server rooms to manage the far four rooms in each floor. The network subnet layout enables administrators to quickly locate computers by IP address by building floor and room, and whether the computer is a server, staff computer or instructor’s computer. The subnet layout minimized the broadcast traffic that can reduce network performance by limiting the number of computers in each broadcast domain. The subnet layout also provides for efficient use of IP addresses by including only the number of IP addresses in each subnet necessary to support current computers plus a few additional IP addresses for immediate expansion when required. For security reasons and to differentiate subnets, The first digit in the third octet designates to the floors ( 1 for the first floor and 2 for the second floor). The second digit designates to the group ( 1 for Instructional, 2 for Administrative network and 3 for the Wi-Fi)

Land That Entry Level Job in 3 Easy Steps

Land That Entry Level Job in 3 Easy Steps Sandy Donovan over at the Career One Stop blog has 3 great suggestions for job hunters feeling shut out at the gates. How do you make up for a lack of experience, a job gap, or a stagnant hiring climate in your dream field?   1.

Know your industry and know yourself, so that when you finally get the call, you can interview as a well-informed, astute candidate.

To Build a Fire and Young Goodman Brown Essay Example | Topics and Well Written Essays - 1500 words

To Build a Fire and Young Goodman Brown - Essay Example Another interesting point is that Hawthorne makes sure to clarify that the journey which Goodman Brown makes into the forest is done at night and not during the day. If any trespasser were asked what comes to his mind with the thought of a dark forest, it can safely be assumed that by and large the first response would be related to the creepy feel that a dark forest exuberates. The dark forest sets the tone of the story and makes it clear to the reader from the start that what he is about to read is not a happily ending romantic novel or a light comedy, rather the dark thought provoking nature of the story comes across instantly. Therefore, the very first role played by the most predominantly used element of nature in the story, the forest, is to highlight the feel of the narrative and set the mood of the story. Time and again references have been made in the novel to the nature of the forest by the use of adjectives such as â€Å"gloomy,† â€Å"dark,† â€Å"silent,â €  â€Å"wilderness,† and so forth. ... As Goodman Brown continues with his journey in the forest he meets an old man, who has not been given a name but it appears to be obvious that Goodman Brown does know that he will be meeting this man and that the meeting was not a coincidence. The conversation between Goodman Brown and the old man revolves around the old man challenging Goodman Brown’s belief in the goodness of the people of the society and his father and grandfather. From this conversation it appears as though the old man represents the devil or the temptation that attracts man towards evil. Hawthorne makes it a point to specify that the â€Å"old† man is sitting under an â€Å"old† tree while waiting for Goodman Brown, so that the reader can instantly make the connection of the old man with evil because there is an inherent eeriness associated with old trees with their sagging roots. Furthermore, the stick which the old man is narrated to be holding is constantly compared to a black serpent as follows, â€Å"But the only thing about him that could be fixed upon as remarkable was his staff, which bore the likeness of a great black snake, so curiously wrought that it might almost be seen to twist and wriggle itself like a living serpent,† (Hawthorne, 8). Here we see another element of nature coming into play, the snake is said to be amongst the most venomous of all animals and the fact that the old man holds this stick with such comfort reflects on his association with evil. An interesting piece of conversation from the story is as follows, "Come, Goodman Brown," cried his fellow-traveler, "this is a dull pace for the beginning of a journey. Take my staff, if you are so soon weary,† (Hawthorne, 9), this suggestion of the old man to Goodman Brown can have

Non-Governmental Organizations Essay Example | Topics and Well Written Essays - 2750 words

Non-Governmental Organizations - Essay Example In numerous countries, NGOs have led the way in democratization, in battling diseases and illnesses, in promoting and enforcing human rights, and in increasing standards of living. (Christof Galli) Although most NGOs are working for aid and relief, they have other functions as well, for example promoting education, healthcare, for businesses, political or social goals etc. Also NGOs are not entitled to work in their own respective cities or countries; there are a number on international NGOs (INGOs) which work on an international basis, or by establishing partnership with NGOs of different countries to work towards a common cause. As far as partnership among different NGOs is concerned, although they are all working towards a common interest, yet due to difference in their culture, economic state such as an NGO in a developing or a developed country, their working style etc differ from each other and thus=s leads to some problems. The purpose of this paper is to explore these problems that occur due to partnership between NGOs of different countries, from the perspective of both the developed countries such as Japan and developing countries. When working with an individual or an organization, whether it is a profit or a nonprofit organization, one of the very fundamental rules it to know the 'rules of the house'. As in case of Japan there are certain etiquettes one needs to be aware of while dealing with Japanese people. Japan has a collective culture, therefore for you do business there you have to be part of the working pattern, and explain your stance rather than taking initiatives on your own. Another important thing to know about Japanese is that they avoid using direct style of negotiating and use vague terms rather than bluntly saying "no" to something. According to Richard D. Lewis, "Don't try to be accurate in Japanese. The Japanese deliberately create ambiguity and so they answer questions indirectly - the famous thing about Japanese never saying no. They won't say anything to offend and when they are deliberately vague, they leave their options open. If you know Japanese grammar, they don't have persons like we have. There is a "going". You don't know whether you're going or we're going or he went. It's a vague language." Other tips, to be kept in mind while negotiating with Japanese include that Japanese usually view meetings to be aware of the other party's position on a certain agenda and look forward to private informal appointments for decision making purposes. Also a decision is made via consensus of the entire group involved, therefore one should not display individuality. According to Stephen Pearlman, Public Relations Manager Japan Airlines, "One of the frustrating things for a non-Japanese person in a meeting is the lack of exchange of ideas. It's quite typical for it just to be a place to report information, so it's not the kind of aggressive throwing around of ideas that you probably experience in a non-Japanese meeting." In Japan, a lot of time is dedicated to work and the organization one is working for, which will be expected from anyone who is doing business in or with the Japanese. Also, criticism is not expressed in public; rather more subtle ways are used to ask concerned questions. Japanese NGOs -- Their Origins and

Slavery Essay Example | Topics and Well Written Essays - 500 words - 1

Slavery - Essay Example Freedom was the greatest development more so because during the civil war, the rights of the African Americans were greatly infringed. They were used for the war and were viewed as disposable people. This was a great disadvantage as their families were not taken care of. The men were front lined during the war and this led to many deaths of the African Americans during the Civil war. After the civil war, slavery was abolished and people could now get employed. Others were given land for relocation and they started up their own small scale farming. This is seen to have led to creation of institutions such as schools, churches and even African American magazines such as the Freedom’s Journal. These institutions became the basis for equality another great step in the History of the United States. Industrialization was another great development that arose from the Civil War and colonial period. When slavery was abolished, the farmers in the big plantations in the South still required labor. In the North, many industries were growing from manufacturing industries to banks among others. Industrialization in my opinion allowed blacks to implement their skills efficiently and to earn a living from it. Although it was difficult to start up because racism was not yet at a halt, it ensured that some if not most of their rights were protected. They could also vote and work for pay which enabled them to choose their leaders. On an overall in the present, if this hadn’t happened, the United States would never have achieved equality to the point of choosing an African American president. Industrialization though many may say was full of monopolies, still ensured that many grew their societies and their families. Though the African Americans mostly received bad treatment and less pay even with freedom, it was on the other hand much better than slavery in itself. Industrialization is what led the United States to be the super power it is today

No Coward Soul Is Mine Analysis

No Coward Soul Is Mine Analysis Emily Brontes No Coward Soul Is Mine was written in order to reach out and touch faith so to speak. Death, faith, and passion were things that did not run scarce in Emily Brontes life and with that No Coward Soul Is Mine was inspired and written. Writing to cope with the pain of growing up, neglected and uneducated Bronte reaches out to God to fill her wounds and give her a life after life. Within No Coward Soul Is Mine, Bronte whole heartedly reveals her views on God through the poems theme, provides descriptions of her interpretation of God himself as a character, allows the reader to illustrate what she sees through nature, and also pulls the readers attention with her use of passionate and powerful words while setting the tone of the poem. In No Coward Soul Is Mine, the main purpose for Brontes use of first person is to express her thoughts, beliefs, and views on God and how other things relate back to him like faith and death (Fernà ¡ndez). Emilys beliefs are that God is everywhere and is the source of everything. She wants to show the world that God is her life and reason to live and does so in her own way. Her thoughts are brilliantly used in the form of nature, providing unique descriptions of nature to depict what God is like. Brontes beliefs are shared and expressed through her metaphoric use of faith throughout the poem, whether it is the breath she breathes, or her never ending love and adoration for God. Her view on God is moving and full of enthusiasm keeping the reader listening and wanting more of Brontes thoughts. In her very first line of the poem, where she states, No coward soul is mine (Bronte, p. 948), she wants to prove to everyone that she isnt a coward through God and never will be, and by making this quote the title enforces its importance to represent her as a strong and independent woman with the partnership of God. No Coward Soul Is Mine is also a very affectionate and emotional poem that Bronte allows the reader to feel and react to. Bronte allows the reader to effectively view her morals and values. The poem permits the reader to interact with and relate to where the author is coming from in an easy perspective. In addition, the poem represents a sense of reflection of Bronte herself and opens up her opinions and beliefs to the reader while also depicting her relationship with God. Her thoughts are obvious since the portrayed image of her character of God is very descriptive and personal, which is why it was written in the first-person. Brontes character of God is not a character at all but actually her faith and principles. In the first stanza she writes Heavens glories shine and Faith shines equal arming me from Fear (Bronte). In this line, she is saying that through God and faith she is fearless. Faith is the belief in something that cannot be seen, but in which one has complete trust (Fernà ¡ndez, 2000). In the second stanza, her character is strong and she states that anyone can possess him. Bronte is preaching about God and telling the audience what he can offer them and continues in the third and fourth stanza encouraging the audience to look away from evil and vain and to trust and give your faith to God. She continues on and compares her character to rocks and other objects in nature that symbolize someone that is strong not only physically, and emotionally, but also spiritually. She also makes references to the breath that we breathe and that gives us life although we cannot see it. Much like in The Pulle y by George Herbert, the character of God is so powerful and giving just at Bronte states. Herbert states that God gave us all of our blessings all of which are strength, wisdom, pleasure, beauty and honor. This poem also portrays a close relationship with the character of God (just as No Coward Soul Is Mine does), and also explains how man provides his respect for God through only Gods knowledge of eternal rest. Both poems give their character use of Gods recognition to the highest power and with nothing less than respect. Even though they cannot see him physically, they spiritually both reach out to him. His spirit is not dead, he is made one with nature, he is a presence (Pinion, 1975). Bronte is sure of two things: her faith and the certainty of Gods existence. Through nature, Bronte provides the reader with brilliant images of whom and what she sees as signs of a presence of God. No coward soul is mine, No trembler in the worlds storm-troubled sphere: I see Heavens glories shine, and faith shines equal, arming me from fear (Bronte, p. 948). Bronte Speaks clearly and gives the reader a chance to understand exactly what message she is portraying and providing clarity in her visual images. In this excerpt, she carefully paints the image of everlasting love and faith, also the afterlife. Her images are colorful and exciting and she uses large amounts of enthusiasm to express her feelings and expresses those by using powerful images of nature. By using physically powerful images throughout the poem to praise and worship God, she gives the audience a very clear and precise understanding on how God is portrayed through her eyes. As upbeat as most of the poem is, she also uses some degrading imagery, mostly towards those who live their lives in vain and continue to do so. Her strict intolerance is quickly expressed through her one simile in the poem which contains st rong use of vain. In moments of vision, religion can pierce the veil and become one with the universal and external spirit (Winnifrith Chitham, p. 59). Bronte also expresses how death is not to be feared and that even after you stop breathing your spirit and faith will live on somewhere. There is not room for Death, Nor atom that his might could render void: Thou -Thou art Being and Breath, And what Thou art may never be destroyed (Bronte, p. 948). She uses numerous things to associate God with and does so effectively and efficiently without confusing the reader. Even when speaking of death she does not disappoint the reader with a drop in tone; however, somewhere throughout the vivid images she does lose the rhyme of the poem although the tone seems to flow fine and smooth without it. The tone in No Coward Soul Is Mine is passionate, while the language is uplifting, emotional and even accusatory. Faith, death, and passion keep an even and overall happy tone throughout the poem. Using faith and passion to keep the reader content and open-minded, but also by using death to pull the reader back to reality, she balances the tone perfectly and does so without confusing the reader. The poem contains mostly metaphors with the exception of one simile which is referring to men. Worthless and withered weeds. Or idlest froth amid the boundless main (Bronte, p. 948). The use of the word as and the particular simile used here gives this phrase a nice tone, and also expresses Brontes contempt for the vain men (Elite Skills Classics). However, Brontes metaphors are not to be looked at individually but as a whole. Together they are characteristics of God and what he is through her eyes. Her religion is everything and without her faith she is nothing. Her commitment to her faith i s astounding and it is all based on her trust in God which she conveys in the overall tone by appearing to be so clam and care free throughout No Coward Soul Is Mine. Bronte uses these metaphors to exult God through the poem (Pinion, p. 201). She is not afraid of death because she knows that God will give her some kind of life after she is gone. She is not tolerant of those who take her God in vain or act in vain. She wishes to become a slave inseparable from her religious thoughts (Davies, p. 173). Overall the tone is conservative which is completely appropriate for Brontes religious and touching poem. Emily Brontes No Coward Soul Is Mine is a clear display of a strong faith and belief. Death, faith, and passion are what drive Bronte to continue to keep her faith in God and what he stands for. She is spiritual and expresses so within No Coward Soul Is Mine. Bronte whole heartedly reveals her views on God through the poems theme, provides descriptions of her interpretation of God himself as a character, allows the reader to illustrate what she sees, and also pulls the readers attention with her use of passionate and powerful words, while setting the tone of the poem.

The Poisoning of Our Ozone Layer :: essays research papers

The Poisoning of Our Ozone Layer The poisoning of the Earth’s ozone layer is increasingly attracting worldwide concern for the global environment and the health effects of life on the Planet Earth. There is not just one particular cause for the ozone’s depletion; the accumulation of different pollutants into our ozone layer has all added up and equaled a worldwide problem. There is not just one effect from the poisoning of the ozone, but instead multiple ramifications from diseases to death. The damage to the ozone is increasing with every second; moreover, there are many ways we can help reduce the problem and preserve the ozone layer. Ozone is a pale blue gaseous form of oxygen, in chemical form it is also known as O3. Ozone can be beneficial or harmful depending on its location in the Earth’s atmosphere. If the ozone is located in the troposphere (which extends from the surface of the Earth up to approxiametly10 miles) it is a harmful pollutant and a major component in smog and other environmental health problems. Such tropospheric ozone can damage plastic, rubber, plant and animal tissue. Ozone located approximately 10-25 miles above the Earth’s surface, in a part of the Earth’s atmosphere called the stratosphere is very beneficial. The ozone is a major factor that makes life possible on Earth. About 90% of the planet’s ozone is in the ozone layer. Ozone in this layer shields and filters out the Earth from 95-99 percent the sun’s ultraviolet radiation. A low level of ozone does not protect or prevent the sun’s ultraviolet rays from reaching the surface of the Earth, therefore, overexposing life on Earth causing many diseases. The depletion of the ozone is caused by many factors, but the one cause that will be elaborated on in the next paragraph is the main reason our ozone is continuously being poisoned. The major cause in the depletion of the Earth’s ozone layer is because of the release of chlorofluorocarbons into the atmosphere. Chlorofluorocarbons also known as CFCs, are industrially produced chemical compounds that contain the elements chlorine, fluorine, carbon, and sometimes hydrogen that will break down the protective ozone in the atmosphere. Since CFCs are heavier than air, the process of CFCs reaching the ozone will generally take from two to five years to get into the stratosphere. When CFCs reach the stratosphere, the sun’s ultraviolet radiation cause them to break apart.
