Operating System common on the Internet Essay

This paper discusses the various types of operating systems that are commonly used for the internet. The paper explains the general meaning of the operating systems and then discusses the various types of operating systems which support the internet applications. An operating system is a software component of a computer system that is responsible for the management of various activities of the computer and the sharing of computer resources. Operating Systems provide a base software platform on top of which other programs called application programs can run. Operating systems enable user to interact with the computer systems by acting as an interface between users or the application programs and the computer hardware. The different operating systems available in the market offer a wide choice for the user. However, with the increasing internet usage, the choice of operating system greatly depends on how well the OS supports the activities of the internet based applications. The different operating systems provide different types of browsers to enable internet usage. Linux is the most popular operating system for the internet and is based on UNIX, just like the Mac OS X. Linux offers larger amount of free space and open source software and is more equipped than any of the other counterparts. Comparing the features of the various OS, Hughes states that one of the most important features of the Linux operating system is its set of internet clients and servers including mail, news, FTP, web as well as the proxy clients and servers. Owing to the range of Linux distributions to offer, Linux is easily customizable. The use of compatibility layers such as Wine, makes Linux attuned with the windows programs and hence a good choice for the internet. The system is less prone to viruses and hence more reliable, especially for the internet. The system is freely available and far less expensive. This advanced operating system is most popular and recommended for internet users. BSD operating systems are very similar to Linux operating systems and fully support internet access. Both Linux and BSD come with full functionality for regular dial-up, PPP-based, cable modem, and Ethernet connections. Sun Operating system, which is a part of Sun Microsystems Solaris, is yet another OS commonly used for internet networked applications (Linfo, 2004). Although not so commonly used, BSD and IRIX also considered as good operating systems for the internet applications. Linux is considered to be safer for web hosting servers. It is found to b more reliable, stable and efficient (Internet-Web Hosting). Microsoft Windows has been the most common operating system. The series of operating systems started with MS_DOS, Windows 95, Windows NT, XP and the now popular Windows Vista. Owing to the largest library of programs and applications, and the ease of hardware compatibility that it renders, Windows continues to be one of the commonly opted operating systems. However, considering the performance speed and security issues, Windows might not be the best choice for the internet. Windows operating system is prone to viruses and spy ware because of which it necessitates the installation and maintenance of the internet security software. Apple’s Mac OS X is the second most popular operating system based on UNIX. The OS is relatively simpler and more compatible. It offers many advanced features along with an intuitive interface. Mac OS X supports second largest selection of software and is the most reliable operating system. Unlike the Windows Operating system, Mac OS X is not prone to virus or malware and is a better choice for the internet when compared to Windows for certain cases. However, the limited compatibility with the Apple hardware imposes a constraint on the system being used across the internet. Unlike the Windows, the Mac OS X does not require the frequent expenditure on the internet security software subscriptions and is thus less expensive as compared to the Windows. The choice of Operating Systems for running Internet applications primarily depends on the type of user. While Windows may be the choice of home and leisure users, Linux is generally used by professionals. Windows offers ease of use whereas Linux provides Security and Open source.

Students and Literature Circles Essays

Students and Literature Circles Essays Students and Literature Circles Essay Students and Literature Circles Essay Essay Topic: Students Literature circles involve students in rich conversations about what they had read. Students can express their opinions, predictions and questions about the book they read. Working in a literature circle taught me a lot of things. First I learn that I interrupt my group members when their talking and I do not wait until it my turn to talk. I also learn that I should let the quiet students in my group talk first. First of all, during this project, I learn that I interrupt by talking a lot. For example, there was a day when a student (A) was talking, and I wasnt paying any attention to him. Instead, I was chatting with the person next to me. It made the whole group is not paying attention to him too, just because of me. The other day when the student (D) was talking to me, I got out of the topic, and I started to talk about something else and my group join in too/. It made the student (D) mad. However after a couple of meeting in a literature circle, I learned how to wait for my turn to talk. For example, when a student (C) was talking to the group I wanted to say something, but I waited until the student (C) asks me what do I think. The student (C) did not start with the quiet students in my group to talk first instead he started with the students who are not quiet. When we started working in a literature circle, we did not let the quiet student talk first. For example, when I was the Discussion Director I did not ask the quiet students to talk first instead I asked the others students who were not quiet. When was finally their turn to talk they just agreed with other students and they did not talk the much. In addition, each time when my group are having a conversation it not really an open conversation. For example, when the student (D) was discussing about the drawing he made we started having a little conversation. The conversation was not a really open because the student (D) did not asked the quiet students first. It was diffic

Persepolis Essays

Persepolis Essays Persepolis Paper Persepolis Paper Effects of Violence on Marli Although violence is intended to harm someone, there can be positive effects in certain situations. In MarJane Satrapis personal memoir, Persepolis, it is shown that Marli is exposed toa large amount of violence in her life, and in turn, it has affected her in many ways. The negative effect on her life include the emotional scarring that entails deaths from violence and also her increased violent tendencies. A positive effect of violence on MarJis adolescence is that she becomes more mature and is able to stand up for herself. MarJis exposure to the difficult times around her define ho she is as an individual, how she behaves, and how she matures. As a child is growing up, the people around them affect them greatly, and the violence around Marli and her life is emotionally scarring to her. Her Uncle Anoosh was executed for being a Russian spy, and she cared for him greatly. After she receives the news, she is visited by her image of God, and during this brief appearance she shouts at him, saying, Shut up, you! Get out of my life!!! I never want to see you again! (Satrapi 70). This quote is quite strong for MarJi; it is shouted in a iolent manner that is fairly unusual for her. She is very torn up about the situation that is at hand, which in itself is aggressive, and she is trying to cope. Usually this God is a comforting friend, a figment of her imagination that she created to try to understand the world around her. In this case, she feels that it is his fault that her uncle was executed. She tells him to leave because she doesnt trust him, especially since she is in a unstable, mourning condition. In the image Marli is standing on her bed, pointing to guide God to leave her. God looks sad or disappointed, but almost ike he expected it, and is accepting of his banishment, which could translate to him feeling guilty about the situation. The blackened background gives the impression that the main idea is her and God and also that she is starting to feel lost in her sadness and the enormity of the fact at hand. The way she is standing on the bed gives her power when she is possibly weak, making her seem taller and steadier. Another more graphic case of violence in MarJis life was the bombing near her house. Her neighbors house was bombed, and it is inferred that they were killed. After seeing what she believes is a hand, she explains, No scream in the world could have relieved my suffering and my anger (Satrapi 142). She was friends with her neighbor and is very difficult to have such a harsh visual in front of her. It was especially traumatizing for Marli because it was so close to her home and she must have thought of the possibility of that being her family. The panel for this phrase is just darkness, which expresses MarJis grief and her emotions clouding her thinking. She cant think of anything other than mute blackness because of the shock she feels. In both of these situations, someone close to Marli has been brutally killed, whether it be by assassination or bombing. Marli has been through a lot in her life, but deaths like this will stay with her forever and affect the weight of her memories. Prolonged exposure to certain behaviors can lead to slight mirroring of these habits which applies to Marli and her violent tendencies. She is susceptible to the of being fierce, threatening, and occasionally rude. For example, when Marli is very young, she hears that her friend Ramins father killed thousands of people, and creates a plan to punish him. She explains that her idea was to put nails between our fingers like American brass knuckles and to attack Ramin (Satrapi 45). Marli clarifies that she got the idea from hearing about American brass knuckles, something that should not be conveyed to young children. She came to the conclusion that Ramin should be punished very easily, only discovering it from word of mouth. According to Ramin, his father only killed evil communists. Based on this information, it can be inferred that Marli acted severely and irrationally, and effect of her exposure to the issues around her. In the image, Marli and a few of her friends re stomping through the streets, looking for Ramin, who is hiding behind a tree, looking very scared. The expression MarJis face and her stance is very similar to the panels that show protests and demonstrations. The tree that Ramin is hiding behind has only a single leaf on its otherwise bare branches, which could show the lack of protection Ramin has. Marli is very strong willed and opinionated and this is shown through her actions, such as when she is influenced by violence and destruction around her. After she learns that Iraqi bombs were dropped on Tehran, she reacts uickly, exclaiming, The Iraqis have always been our enemies. They want to invade us We have to bomb Baghdad! (Satrapi 81-2). Marli has been exposed to the bombings around her and she immediately wants to respond in a negative way, by fighting fire with fire. For an adolescent, these are strong topics to be dealing with and her voice on the matter is very aggressive. She is very adamant about the decisions she makes, even if she doesnt know all the information. Marli has a habit of being determined about a subject to show confidence and it also works to cover he fact that she might not know all the information. In both these images, Marli is angry and she seems to look like she believes that these behaviors are the obvious answers. She is very strong in her posture and she is defying her father in the first image, showing that she believes she is right and needs to show him that. In the second image, she is saying it in a matter of fact tone, and she has her feet on the table, a symbol of rebellion and confidence. She thinks that she knows they answer and wants to be strong willed about it. Although violence has a negative connotation, it does have the positive effect of ausing Marli to mature and act older than her true age. Ever since she was young, Marli has been fairly independent and opinionated. In her school life, she has talked back to her teachers multiple times. For example, when she wears her bracelet after a warning from the principal, she exclaims, With all the Jewelry you steal from us, you must be making a pile of money (Satrapi 143). This response is followed by Marli hitting the principal and being expelled. This may seem like a bad thing for MarJi, and it is, but it also shows her willingness to stand up for what she believes in. She showed that she is confident and doesnt want to listen to authority figures with whom she doesnt agree. She is an independent young women and her ability to stand up for herself will be useful as she grows up. I think MarJis expression in this panel is key. She looks angry, surprised, and almost disgusted. She knows what she believes is right and she doesnt want anyone to tell her otherwise. The principal is which almost Justifies MarJis action to hit her. Afterward, she apologizes to the principal, because of her natural instinct to try to lessen the severity of a situation. I hink she acts irrationally in this instance because she has learned that in dangerous or violent situations, she needs to act in a way that exerts her confidence and dominance. I believe that the formation of these behaviors is due to Marli toughening her personality to deal with the brutality surrounding her. Another example of MarJis maturing behavior is the cigarette she smokes. As she tried her first one, she said With this first cigarette, I kissed my childhood goodbye (Satrapi 117). She was using the cigarette as an act of rebellion against her moms dictatorship, but this is eflected with the executions of the regimes oppositions and the violence around her in general. Marli feels the need to rebel because she sees her mother as the dictator of the household and rebelling against her is correlated with rebelling against the revolution. It is well know that cigarettes are incredibly destructive to your health and they represent the violence to which Marli is exposed. She sees this act as her development into a grown-up. Being mature in her society is necessary because otherwise it is difficult to support yourself. As it turns out, Marli had to move away rom her family so her independence and growth will help her in her new life. In the final panel, where she dismisses her childhood, Marli looks confident and sure of herself and her decisions. The black background shows that this is an intense situation and all the attention should be focused on Marli and her actions. In the panel before, Marli was crying due to the cigarette but also due to the ideas entailed with smoking a cigarette and the loss of her childhood. She stopped crying for the last panel to show that she isnt afraid and she is ready for what adulthood could try o throw at her. In conclusion, violence has both negative and positive effects on MarJi. There is expected emotional scarring from the visual violence around her and as an individual, she develops a few violent behaviors. On the other hand, Marli has become more independent and grown-up, almost forcefully, from her exposure to the violence around her. Marli was living in a life surrounded by turmoil and destruction and she had nearly no choice but to endure the difficulties around her and work through them, leading to her growth into a stronger individual.

Caregiver Stress

ASC 4126 – The AIDS Pandemic Caregiver Stress Caregivers are those people who provide assistance to other people who are unable to perform certain activities on their own because of a physical disability or chronic illness. Formal care can be obtained at home, or from institutions such as nursing homes, and is offered by trained, paid or volunteer professional caregivers. However, informal care, which is usually offered by family members or friends, often in a home setting, is becoming increasingly common. These caregivers are normally inexperienced, untrained, and otherwise lacking the education necessary to maintain their own good health under the stressful conditions they face. Informal caregiving can have significant effects on the mental and physical health of the caregiver, and this will continue to become an increasing social problem in the United States as the population ages and the number of people requiring care outpaces the availability and affordability of professional care. Therefore, it is important to address the warning signs of caregiver stress, the potential health consequences and the ways in which the stress can be managed. Informal caregiving is becoming an increasingly standard function of many American families. It is estimated that there are 29. 2 million family caregivers in the United States, and about a quarter of them are caring for an aging parent. (McLeod) One of the common unintentional, harmful effects that is a reality in informal caregiving is that there is the potential for the â€Å"illness or disability or injury of the one (being cared for to) become such a focus it almost replaces the rest of their identity†. (Article 8) The same kind of thinking can also be used to explain the health risks that the caregivers themselves face. Caregiving can be very stressful, time consuming and demanding. Informal caregiving, which is usually a healthy spouse, child or parent living with the disabled person at home, can be a 24 hour, 7 day a week responsibility. It can consume all of their free time, and therefore the caregiver could potentially lose their own identity, and become unable to recognize the warning signs of their own health deterioration as a result of their commitment to caregiving. These caregivers, as part of losing their own identity, may be putting there own needs behind the needs of the person they are caring for. The result of this is that many of the warning signs that the caregiver is risking their own health are either overlooked, or attributed to being overwhelmed or tired from the extensive amount of time and energy that is required in caregiving. It is important for caregivers to educate themselves about the signs or symptoms of caregiver stress so that they can be sure to maintain their own good health. This is the only way to continue to be able to care for their loved one, as well as to help prevent a medical situation in which they could eventually require full time care themselves. The warning signs of caregiver stress vary from person to person, but doctors and psychologists have formulated general symptoms that people should pay attention to. At risk caregivers may exhibit denial about the disease or its severity, anger at the person with the disease, an inability to concentrate and severe irritability. Other psychological conditions could include depression and anxiety, dulled emotions and frequent memory lapses. They might be quick to cry or get angry, or have the consistent feeling that they simply can not cope anymore. Physical symptoms could include chronic fatigue, headaches, stomach aches and sleeping difficulties. Caregivers might even notice that they are catching colds more often than normal, or that they are experiencing an increase in their smoking, drinking or drug use. About 30% of caregivers use psychotropic drugs, such as sleep-aids, compared to only 20% of non-caregivers. (AlzheimerSolutions) Caregivers should also recognize warning signs in other aspects of their life as well. In their social life they may feel isolation or withdrawal from their friends, or be less interested in activities or events they usually enjoy. Another signal may be reduced effectiveness at their job, or in their other family responsibilities other than the caregiving. (McLeod, Maritato) Doctors and psychologists agree that if a caregiver experiences several of these symptoms, that they should consider themselves at-risk for medical complications themselves, and realize that their ability as a caregiver may become compromised. The importance for caregivers to recognize these symptoms and make the necessary lifestyle changes can not be understated. It is especially important for elderly caregivers, most of whom are caring for their spouse. It has been shown that a caregiving spouse between the ages of 66 and 96 who experience some type of emotional or mental strain have a 63% greater chance of dying than those in the same age group that are not caregivers. (Caregiver. org) But it is not just the elderly that develop serious medical problems related to their caregiving responsibilities. Caregiving related stress can have a severe impact on the immune system, which in turn has a direct influence on our overall health. Even wound healing is affected by the stress associated with caregiving because of the impact on the immune system. One study shows that wounds, such as cuts, take 24% longer to heal in Alzheimer caregivers than in non-caregivers. (AlzheimerSolutions) A weak immune system will also result in an increased rate of infections and serious illnesses. Therefore, caregivers are at an increased risk of contracting common colds and the flu, as well as more serious, chronic illnesses such as heart disease, diabetes and cancer. O’Brien) Research has shown that 51% of caregivers with significant responsibilities have sleep difficulties. (O’Brien) Lack of sleep can result in decreased effectiveness at work and at home, as well as impairing the ability to be a functioning caregiver. This symptom of caregiving can also have severe health consequences. There is increased research that shows a direct relationship between sleep deprivation and a heightened risk of many major illnesses, i ncluding heart disease and obesity. O’Brien) Finally, it has been proven that the stress associated with caregiving can actually shorten a person’s life if they don’t pay attention to the warning signs and maintain their own good health. This is not something that only the elderly needs to consider, because caregiving stress can affect the physiology of all caregivers. It has been shown that chronic stress can â€Å"accelerate the effects of aging by actually shortening cell life, (because) it leads to weakened muscles, skin wrinkles and even organ failure†. These studies found that this type of chronic stress can potentially shorten a caregivers life by as much as ten years. (O’Brien) In order to prevent these serious medical conditions, caregivers must not only watch out for their personal warning signs, but also find ways to manage the stress of caregiving. Most importantly, caregivers need to take care of their own health. This includes regular exercise, eating nutritious meals, and maintaining regular sleep patterns. Regular medical checkups are also essential, especially if the caregiver is experiencing some of the warning igns mentioned earlier. Perhaps this is the most overlooked necessity, because of either the lack of time, or the constant focus on the person being cared for. It is estimated that caregivers average four doctor visits per year, while non-caregivers average seven. (AlzheimerSolutions) Other ways that caregivers can manage the stress include maintaining their social life, especially their friendships and ot her social relationships, which can serve as a much needed break, or â€Å"escape† from their responsibilities as a caregiver. Caregivers should also be willing to ask for and accept help from others whenever possible. This can include other family and friends, or community organizations such as a local Area Agency on Aging, faith based groups or adult day centers. Adult day centers are basically there to provide relief for caregivers. They provide social activities and minimal medical attention during normal business hours. It is also important for caregivers to have an outlet for their stress, which can be achieved through talking to their friends and co-workers about their experiences. Joining a support group can also be a beneficial tool to learn how to deal with negative feelings. In order to properly manage their stress, caregivers have to learn how to deal with the common feelings associated with caregiving, such as embarrassment, guilt, helplessness and anger, and a support group could really help in that effort. Most people that become informal caregivers do so because of the unexpected illness or injury of a loved one. Because they generally become caregivers without any training or education, they are not usually aware of the possible negative impact on their own health that can be a result of their commitment to caregiving. It is therefore extremely important that caregivers understand the warning signs and symptoms related to the stress associated with caregiving and the potential medical consequences. They need to take advantage of any services available to help them manage the stress, including help from friends, family and the community to ensure that they maintain their own health, and their ability to be a functioning caregiver.

International Service Quality Mystery Shopper Essay

International Service Quality Mystery Shopper - Essay Example In short, mystery shopping is a tool that helps companies in understanding where their services stand and helps them to rectify the problems their customers face and improve their services. 1 Mystery shopping was basically developed in the 1940s and 1950s in order to expose the deceitful employees that were working for companies. In the early days, much of it was carried out by private investigators and many had no idea about what the term actually meant. With the passage of time, many of the companies realized that the information revealed with the help of mystery shopping services was far more authentic and important in helping to improve their business. Also, the information revealed about customer care service issues, safety and environment were also considered important and service providing companies realized that the information about the operations was far more important than any other data (Ilisha, 2004). The most common places where mystery shopping techniques are applied are the services industry, such as movie theatres, restaurants, banks, fast food chains, health clubs etc where much emphasis is paid on the service quality and their customer base and reputation is dependent on it. Therefore, the management of these companies make sure they have sound methods and techniques to gauge their services in a non-biased way in order to correct any faults.2 HOW IT WORKS A mystery shopper first has to register himself/herself to an organization specialized to conduct mystery shopping. There is a Mystery Shopping Providers Association with which companies are registered and provide mystery shopping services to the people. The mystery shopper once registered, is given an assignment, specific to the area in which he or she is living and a number of topics on which he or she has to undertake the assignment. Most of the dealings between the company and the mystery shopper are done online which reduces the hassle of paper work for the mystery shopper and it is a source of easy money for many. MYSTERY SHOPPING AND MARKET RESEARCH Mystery shopping is considered as a tool of market research as it helps to understand the market a company is catering too. However, it is different from market research on many accounts. Mystery research is more associated to operations research. Mystery research is more of an operational research that provides feedback on quality control, training and inducement purposes. These shoppers are specially recruited in such a way that their demographics and social profile is similar to the target market of the organization. Mystery shoppers also visit certain areas and on certain times, it cannot predict every customer's opinion and experience of the service (Mystery-Shoppers.co.uk, 2008). Also, customer satisfaction cannot be gauged because a mystery shopper is just a job that the shopper is doing and customer satisfaction relates to the subjective idea of a real customer's thinking. Therefore, mystery shopping should just not be used to gauge customer satisfaction. Mystery shopping provides us with a unique feedback of the customer and the people who are the mystery shoppers exactly know what they have to evaluate and the front line workers who are being evaluated have no idea about it. However, ethical

Freedom of Speech and a Free Government Essay Example | Topics and Well Written Essays - 500 words

Freedom of Speech and a Free Government - Essay Example One of the areas that free speech is universally held as sacred is the freedom of religion or even the freedom from religion. (Matthew D. Bunker, 2001).One of the interesting facts of life is that the Supreme Court has never decided what free speech is. The court has allowed that free speech is associated with the search for truth. Even unpopular opinions are allowed the right of free speech. Freedom of speech is very important in the development of political stances that individuals might take.   Through freedom of speech various ideas can be developed and debated in order to establish a defensible position. It has been said that the right to express ourselves and the right of others to hear us contributes to the ordinary happiness of human beings, in general. With that being said, there are things not protected by freedom of speech. One cannot obstruct the recruiting or enlistment for people to serve in the military. Libelous talk or press and false advertising are also restricte d.   In general it is not permissible to wear gang colors to school or to wear anything that promotes hatred. Also not covered by free speech are personal threats of violence made against a government worker or an educator. The First Amendment of the American Constitution is perhaps one of the best known governmental documents of all time. The government as created by the representatives would be composed of three branches. The executive would be the leader of the entire union supported by a two house legislature.

Copyright law Essay Example | Topics and Well Written Essays - 750 words

Copyright law - Essay Example â€Å"Work made for hire† is defined under  § 101, Chapter 1 of Title 17 on Copyrights of the US Code as work, which is either prepared by a person as part of his work during his employment or works which are especially commissioned. The ‘work made for hire’ rule constitutes an exception to the general rule that copyright ownership naturally belongs to the author or creator of that work, implying that in such cases, the employer or the person for whom the work is done or created for is deemed the copyright owner of the work.However, this can be true only if there is no express agreement in writing signed by the parties indicating a contrary intention ( § 210, Chapter 2 of Title 17, USC). Under the first definition of ‘work made for hire,’ the term employee is constructed in accordance with the holding of the Court in Community for Creative Non-Violence v Reid, 490 US 730 (1989). In that case, an artist’s help was solicited by a non-profit o rganization to aid in their campaign against homelessness. The artist acceded, but no agreement between them as to copyright ownership over the sculpture was entered into. When the artist later claimed copyright ownership, the organization went to court. The US Supreme Court held that the term ‘employee’ should be taken in the context of the conventional employee-employer relation, without resorting to the control test often employed in common law. The SC’s decision relied on the agency law, where agency is determined under a ten-factor test. Since the conditions in the case did not satisfy this, the Court held that it was not within the ambit of the ‘work made for hire’ and copyright ownership belonged to the artist. On the other hand, ‘work made for hire’ under the second type, or the especially commissioned works, is easier to determine because the law itself confined it to nine types of work: â€Å"as a contribution to a collective work; as part of a motion picture or other audiovisual work; as a translation; as a supplementary work; as a compilation; as an instructional text, or; as an atlas, if the parties expressly agree in a written instrument signed by them that the work shall be considered a work made for hire† ( § 101, Chapter 1 of Title 17, USC). Q2 Under  §102, Title 17 on Copyrights of the US Code, there are eight kinds of works of authorship upon which copyright protection can be had: literary works; musical works, including any accompanying words; dramatic works, including any accompanying music; pantomimes and choreographic works; pictorial, graphic and sculptural works; motion pictures and other audiovisual works; sound recordings, and architectural works. Copyright registration may be made either online or using paper forms, although online registrations can only be made for basic registrations. For non-online registrations, each type of work of art must use a corresponding form. Liter ary works, whether published or unpublished, for example, must use Form TX. Specifically Form TX is used for non-dramatic literary works such as fiction, non-fiction, poetry, textbooks, reference works, directories, catalogs, advertising copy, compilations of information, and computer programs. On the other hand, visual arts, published or unpublished, must use Form VA, with ‘visual arts’ comprising pictorial, graphic, and sculptural works. Works of artistic craftsmanship and design are also registrable under Form VA, but protection extends only to their form and not to their other aspects. For works of performing arts, published or unpublished, Form PA is used for registration. The performing arts category include within its ambit musical works, dramatic works, pantomimes and choreographic works, and motion pictures and audiovisual works. Form SR is the form used for the registration of sound recordings, published or unpublished, but may also be used to simultaneously r egister the underlying musical, dramatic or literary work accompanying the sound recording. Sound recording, however,
