Computer technology - Essay Example Computer systems consist of both software and hardware. The hardware components are tangible components of the system: main memory, CPU, peripherals such as monitor, video display etc (Gookin 2006). Software part is the set of instructions that define what the actions of the computer hardware (Alagar and Peryasammy 2011). Typically a computer requires both the system software Minimum user requirements Fred, Barry and Jane need a Single PC for their gaming needs. Frankly, there are no many options for a PC with the minimum requirements they desire that can go for the price in their budget estimate of 350. For a gaming PC no existing integrated graphics acceleration cards can handle the processing requirements of the game. In this case a graphics processor that is dedicated will still be required. OS: Windows Vista or Windows 7 Processor: Core 2 Duo 2.4 GHz or Althon X2 2.7 GHz RAM: 2GB Graphic card: DirectX 10 or 11 compatible Nvidia or AMD ATI card, ATI Radeon 3870 or higher, Nvidia GeForce 8800 GT or higher. Graphics card memory: 512 MB Sound card: DirectX compatible sound card Hard drive: 15 GB for disc version or 10 GB for digital version Fig. 1 Complete desktop computer The retailer has the option of making a choice between several brands, manufacturers of computers; Dell, Hewlett Packard and IBM. In my assessment I would recommend a machine that is high performing with the functionality that can well fit the gaming requirements. Since the budget constraints the selections, the best option is to go for the components that are most important in supporting gaming requirements. The computer features most essential for a gaming machine are; processor, graphics card, internal memory and hard disk capacity. Compromising on other desired features such as sound will not harm the game and the advantage will be the cost cuts. Justification Quad-Core Processor Though lesser processors such as dual-core are cheaper and within the budget, the ability of a quad core to s upport a larger number of tasks at the same time is a must for serious gaming. This is a good processor will help the computers to run effectively. The processor is the brain of the computer and controls most of the work done by the PC. For gaming requirements, multimedia multitasking, for example video recording while browsing will give a more pleasant experience. Processors are generally defined by their speed - in megahertz (MHz) or in gigahertz (GHz) - and it relates to the number of operations they can perform per second. The higher the value, the faster the PC will perform and the more expensive it generally is. I will recommend the Quad-Core AMD Opteronâ„ ¢ Processor with Direct Connect Architecture are designed to deliver industry leading power efficiency, optimal virtualization, outstanding performance, and low TCO - all within a consistent footprint and thermal envelopes. Fig. 2 Central processing unit AMD Phenomâ„ ¢ X4 Quad-Core Processors is a true quad-core perfor mance for the way gaming multi-task today, and for the next-generation applications that will be needed in the near future. Stable commercial AMD Phenomâ„ ¢ X4 quad-core processors offer industry-leading platform stability and longevity, investment protection, and the exceptional performance you expect from AMD. In addition, the processor comes with unique features for energy efficiency ‘AMD’ (2011). Random Access Memory (RAM) The computers will need about 4 gigabytes of memory so that they can run

Near field communication (NFC) and its validity as a secure system of Essay

Near field communication (NFC) and its validity as a secure system of data transfer - Essay Example Being a non-contact technology, the NFC is highly advantageous as it does not require establishment of physical electrical contact. As such, in applications such as those requiring the use of cards, there is no need of inserting cards that use NFC into the reader, thus avoiding any problems that may be associated with poor contact. It is important to note that NFC uses inductive-coupling at a license free frequency allocation in the radio spectrum HF portion(Ahson & Ilyas, 2012, p. 33). NFC has a set of standards that govern it thus allowing for connectivity between NFC devices from different manufacturers. Besides creating the contactless environment for NFC interactions, the standards also determine the data transfer rates and the data formats. An NFC connection is simply achieved by bringing two electronic devices together within a close range to allow them to communicate. This eradicates the problem with identification and minimizes the issue with security, allowing for easier exchange of information. The NFC can be used for a variety of applications including in: mobile phones to transfer files from one handset to another; personal computers to link up networks for data transmission; point-of sale machines; turnstiles; parking meters; vending machines; and in other applications in the house or office, such as opening and closing of the garage doors(Finkenzeller, 2010, p. 80). The NFC connections could also be applied in the configuration of the connection between two devices that have wireless connections. Bringing the devices together allows for the initiation of the NFC connection which in turn initiates the set-up procedure. Other long-range wireless devices including the Bluetooth could be configured through communication with the NFC interface(Coskun, et al., 2011). NFC are vulnerable to man-in-the-middle (MITM) attackswhich involve attackers succeeding in interception of the communication

Woman Warrior Essay -- essays research papers

A Warrior’s Triumph   Ã‚  Ã‚  Ã‚  Ã‚  The Woman Warrior by Maxine Hong Kingston presents the story of a girl trapped between the cultures of her surrounding environment and that which her mother and family have forced upon her. Knowing only the Chinese way of life, this girl’s mother attempts to familiarize her daughter, whom is also the narrator, with the history of their family. The mother shares this heritage through the use of stories in hopes the narrator will be prepared for her ultimate return to China, which is a life completely foreign to her own. Through these stories and the strong influence of the surrounding American culture, the narrator’s life and imagination spin off in a new direction. She is confronted by many obstacles, which cause problems with not only her mother, but also with her attempt to discover her personal identity. Although the narrator’s assimilation to the American culture causes numerous conflicts with her mother, she is able to overcome adversity and come of age as a Chinese-American with the help of her mother’s stories.   Ã‚  Ã‚  Ã‚  Ã‚  In Kingston’s first story, â€Å"No Name Woman,† the reader is first introduced to the stories of the narrator’s mother. This particular tale involves an aunt that the narrator never knew, who was shunned from her family for having an affair. It was through this story that the narrator learned how careful a young woman must be when growing up in the Chinese culture. Years after hearing of her aunt’s misfortune, the narrator realizes that she has carried on this ostracism and is equally as guilty as the others who participated in this punishment of silence. However, the narrator feels an intense connection with the outcast of her family. â€Å"My aunt haunts me—her ghost drawn to me because now, after fifty years of neglect, I alone devote pages of paper to her†¦Ã¢â‚¬  (16). Perhaps the narrator feels this bond because she herself feels completely alienated from the family and could never be fully connected to her Chinese h eritage. Although she is angry for the terrible punishment inflicted on her aunt, she feels remorse for â€Å"telling on her† (16). This shows that the narrator does not only disapprove of the Chinese culture, but also feels sorry for those who must suffer in an eternity of exile.   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"White Tigers† brings readers into the creative imaginatio... ... seems to plague the narrator endlessly. She knows she can never break away from one culture without having to completely abandon the other. In the end, however, she realizes that she must leave home if she is ever to discover her purpose in the world, be it in China or America. The harsh criticisms and endless disapproval causes detrimental effects to the narrator, while at the same time giving her strength to overcome this lifelong struggle by facing her mother. Although the stories of her mother’s Chinese experiences and the insistence on her daughter living there push the narrator further away, it eventually causes an interest to discover what is really true. â€Å"Soon I want to go to China and find out who’s lying†¦Ã¢â‚¬  (205). Though some can constantly feel sorry for the narrator, we can also feel sorry for her mother not knowing any better. This is what ultimately caused the nonexistent relationship between the two. Through this complicated life, th e narrator gained the strength, intelligence, and experience that allowed her to overcome numerous obstacles. Contrary to the belief of some, I feel she has her mother to thank for these gains, and that may have made all the difference.

Symbolism in A Rose for Emily - Free Essay Example

Did you ever really understood the power of prejudices and gossip in someones life? The short story A Rose For Emily by William Faulkner, reflects the reality of the life of a southern aristocratic woman, Emily Grierson, who is looked upon as a figure of tradition in an old-fashioned changing society that has her as a subject of criticism and gossip throughout all her life. The story transpires a series of interconnected events including death, the decay of the south, isolation and a search for love that can be shown through literally devices and a Marxist lens to reflect that there are running themes throughout the story. Death of freedom Form of control Death of south after civil after Isolation death of Faulkner utilizes foreshadowing to foretell events that will appear later in the story like the theme of death. Don’t waste time! Our writers will create an original "Symbolism in A Rose for Emily" essay for you Create order The initial use of foreshadowing happens as the beginning of the story introduces the death of Emily Grierson, an event that also is mentioned at the end of the story. The protagonist of a story doesnt usually die at the beginning of the reading, but the author uses this technique to directly make the readers understand the importance of death as it is considered a major theme in the story and almost to prepare them for the multiple deaths later in time. Being death a central theme, it is further symbolized as the powdery dust that coats Miss Emilys house. For instance, when the men went to Emilys house to attempt to collect her taxes, the Negro opened the blinds of one window, they could see that the leather was cracked; and when they sat down, a faint dust rose sluggishly about their thighs, spinning with slow motes in the single sun-ray (Faulkner, 55). Everything around her had dust, it symbolizes death, as it is unmaintained, old, falling apart, reflecting that its useful time is almost done. However, dust is not the only symbol of death in the story. Emily brings a skull and bones into her home when she buys the poison to kill Homer, her lover. This sign on the bottle of arsenic is a bit ironic. The author uses a technique of irony because it is clear to see that Homer will literally be nothing but bones and a skull when the story finishes. The story unfolds in a decaying old Southern house symbolizing a significant theme of the decay of the South which can be related to the major them of death throughout the whole story. The hou se hasnt been maintained or preserved. It is in fact, decaying and deteriorating. Emilys house has once been white, decorated with cupolas and spires and scrolled balconies in the heavily lightsome style of the seventies, set on what had once been our most select street. But garages and cotton gins had encroached and obliterated even the august names of that neighborhood; only Miss Emilys house was left (Faulkner, 54). (isolation) This house represents a memory from the South considering the new generations are modernizing the town and the old south is becoming the New South. The house is described as being built shortly after the Civil War but has become an eyesore among eyesores (Faulkner, 54). Another symbol of the decay of the Old South is Emily herself. Alive, Miss Emily had been a tradition, a duty, and a care; a sort of hereditary obligation upon the town (Faulkner, 55). She is a monument representing the past for the townspeople, but as time goes by, the town has new generations, and the perspective of Emily in the eyes of the townspeople also decays. People in the town then believed that the Griersons held themselves a little too high for what they really were(Faulkner, 57) Emily experiences an unhappy and tragic life far apart from everyone, which brings the theme of isolation in the story. Her father didnt allow her to have a love life. Her father took her away from everyone who courted her None of the young men were quite good enough for Miss Emily and such(Faulkner, 57). So when her father died, she was left alone and depressed to the point she was in denial of his death. After her fathers death she went out very little; after her sweetheart went away, people har dly saw her at all (Faulkner, 56). Her house also symbolizes isolation. Emilys house was where she hid. It represented the past and the place where she was away from the people. She didnt want to belong in any way, even with the mail services. Miss Emily alone refused to let them fasten the metal numbers above her door and attach a mailbox to it. She would not listen to them (IV). She sent Tobe, her negro slave, to do any errands The Negro man went in and out with the market basket, but the front door remained closed (Faulkner, 59). As Emily searches for love in Homer and he doesnt marry her, she kills him. Homers skeleton is a symbol of Emily wanting to hold on to the love she had for Homer. Knowing that Homer didnt want to marry her, she killed him to keep him with her, even dead. He was found at Emilys house coated with dust by the townspeople after she passed away. In a secret room, they discovered that Emily killed him with rat poison and kept his body. What was left of him, rotted beneath what was left of the nightshirt, had become inextricable from the bed in which he lay; and upon him and upon the pillow beside him lay that even coating of the patient and biding dust (Faulkner, 61). This cruel act symbolizes the intense desire she had to have love, regardless of the horrific way she chooses to keep him close to her. She was searching for love and wanted to keep it one way or another. This brings back the feeling of being alone just like when her father died. Social class and isolation were the cause and effect built in the life of Emily Grierson. The Marxist perspective enables one to understand the social conflict in the story. William Faulkner makes a clear division in the social structure between Emily and the rest of the citizens in the town of Jefferson. Miss Emily held the image of a noble lady whose family roots and fame warranted great honor; therefore it is said that she had been a tradition, a duty, and a care; a sort of hereditary obligation upon the town (Faulkner, 55). This social difference placed on her and the towns conflicted obsession with Miss Emily was the major causes why she withdraws herself from the community. She is considered an aristocrat woman in society and is treated like one. The Marxist theory presents proof that social class influences peoples interactions and assumptions about others. For instance, when Emily was in denial of her fathers death, she kept her fathers body inside her house. If any other person, not in such upper-social class as Emily, keeps a dead human in their house will be considered to be insane. When the people found out that Emily kept his dead fathers skeleton, they said, We did not say she was crazy then. We believed she had to do that (Faulkner, 57). This reaction from the townspeople after the incident shows the different attitude they had towards Emilys abnormal act. It was another link between the gross, teeming world and the high and mighty Griersons People considered the Grierson family superior and justified every action they had, whether it was right or wrong. Emilys father even though no men were good enough for his daughter due to this rigid social structure expressed by the Marxists perspective. None of the young men were quite good enough for Miss Emily and such (Faulkner, 57). The conflict arises as Emily is prevented a romantic relationship.

Quick EDUC 6263: Best Practices for Student Success Walden University 1 June 2016 Course Project: Background: Analysis of Structure and Dynamics Institutions of higher education pride themselves in their ability to educate, serve, and meet the needs of the students in which it serves. This analysis shows collaboration on college/university campuses to foster success among first year students. With higher education today being in a state of dynamic change, it becomes crucial that faculty members recognize that their long time traditional roles have become somewhat non-existent. That is to say that there must be a relinquishing of past ideas and procedures.†¦show more content†¦Collaborations are present in learning communities and first year experience programs, but school leaders have to move beyond the norms and work seemingly together to create an environment of success for the students. First year experience programs are prominent on many university campuses but are optional on others. However, these departments utilize career placement counselors, academic advisors, testing coordinators, mentoring options, an d academic success centers to increase the likelihood of students progressing from freshman year through graduation. Upon identifying programs available on various college campuses as they relate to first year students; it has become noticeable that university leaders are concerned with the retention of students within their first and second year of college. Therefore many universities have developed programs that are focused on the success of the freshman student and ensuring that group of students’ matriculations throughout their degree programs. As quoted in â€Å"The Dynamics of Organization in Higher Education (Kuh, 1996) â€Å"the frequent and increasingly predictable accusation that institutions of higher education operate in â€Å"silos† is based on their various schools, colleges, and athletic programs operating in parallel with one another, more focused on promoting than on adhering to or accomplishing broader institutional

Essay on Police Discretion - 1425 Words

Police Discretion Discretion, uncertainly, and inefficiently are rampant and essential in criminal justice. Nobody expects perfection. That would neither be good nor fair. Justice is a sporting event in which playing fair is more important than winning. Law enactment, enforcement, and administration all involve trading off the possibility of perfect outcomes for security against the worst outcomes. Policing is the most visible part of this: employees on the bottom have more discretion than employees on the top. Philosophers such as Ronald Dworkin and H.L.A. Hart have referred to discretion as â€Å"the hole in the doughnut† (doughnut theory of discretion) and â€Å"where the law runs out† (natural law theory). In perspective,†¦show more content†¦Discretion-as-license—discretion is the opposite of standard expectations. It’s the privilege to go against the rules, disobey your superiors, be less than optimal or perfect all the time, all without degenerating the rules or eroding the trust between you, your superiors, or the public. License involves a sense of accountability that does not have to be formally recognized or structural. Discretion is not doing as you please. Discretion is bounded by norms. The future of policing as a profession depends upon whether discretion can be put to good use. Two problems impending police professionalization, however, in that there are few uncontroversial areas in police work, than in other professions. Sometimes the public wants no enforcement, and other times they want strict enforcement.
