The Importance Of Computer Backup Systems

The Importance Of Computer Backup Systems This is used to recompress the files on a disk using the compression method specified. A disk can be recompressed using a single compression method or by using different methods for individual files and folders. Files and folders can also stay uncompressed. This will help save disk space. Disk cleanup: Computer space fills up fast, and being able to quickly make more space is important. Disk cleanup does just that. This is a tool that enables users to clear their disks of unnecessary files. It removes any unused and temporary files from ones computer to make space for new files and programs. Disk cleanup can take a couple seconds to a few hours to remove unused files from the computer. The time depends on how many files are being removed and the speed of the processor. Disk defragmenter: This is the process of resorting all the data on a hard drive so that it starts at the beginning of the disk and is ordered in a chronological nature. It is essential significance to maintaining a properly running computer. The function of a disk defragmenter is to rewrite the data on a hard disk so that all files are written from start to finish and not spread across the entire disk out of order. Defragmenting a hard drive reduces the amount of time it takes to access and read a file. A defragmentation procedure may take anywhere from a few minutes to several hours depending on the size and number of disks on a computer system. Drive Converter: (F) DriveSpace: This is a disk compression utility. This software compresses fate on the fly when the data is to be stored on the hard drive or floppy, and expands the data as it is read from the drive. It increases the amount of data the user could store on disks. However, DriveSpace makes the computer run more slowly, since decompression happens on the fly with every disk access. (G) Maintenance Wizard: This helps one get the best performance from the system. You can run Maintenance Wizard to make your programs run faster, check your hard disk for problems, and free hard disk space. When you start the maintenance wizard, you may choose to express or to use your own custom settings. (H) Net watcher: This is a utility that can be used to monitor the activities of network clients on a particular system. With Net Watcher, one can see who is connected to the system. What shares one is accessing, and what files they have open. One can also at once terminate a users access to the system, a share, or a file. (I) Resource Meter: Resource Meter software displays specific system-related information, mostly about how your available resources like memory space or disk space are currently in use. It is a tiny program that runs in the background and lets you know the amount of resources your system is using at a specified time. It displays as an icon in the System Tray and is color coded. (J) Scan Disk: This is a windows utility used to check the hard disk for errors and to correct problems that are found. These errors often occur when Windows locks up and must be restarted. (K) Scheduled Tasks: It is a component of Microsoft Windows that provides the capacity to schedule the launch of programs at pre-defined times or after specific time periods. It can be used to schedule tasks on the local or remote system to which one is connected. (L) System Monitor: It is a hardware or software based system used to monitor resources and performance in a computer system. These monitoring systems are often used to keep track of system resources or the amount of free RAM. They are also used to display items such as free space on one or more hard drives, the temperature of the CPU and other important components, networking information, and current rates of upload and download. Other likely displays may contain date and time, computer name, username, hard drive, and fan speeds. Question 3: The internet is computer based global information system. It is composed of many interconnected computer networks. The internet has brought a transformation in many aspects of life. Nowadays one can access the internet easily. The internet has developed to give many benefits to mankind. The access to information is one of the most important uses of the internet. Students can now have access to libraries around the world. Before, students had to spend hours in the libraries, but now at the touch of a button, students have a huge amount of information in front of them. Communication is an area where the internet is used for various reasons as it is low cost, effortless and fast. Communication takes place in the forms of emails, chats, video chats and video conferences. E-mail is an important communications service available on the Internet. Email has speeded up business communication on all levels. Usually, it takes only a few seconds for an e-mail to arrive at its destination. This is a particularly effective way to communicate with a group because you can broadcast a message or document to everyone in the group at once. Internet-telephony is another common communications service made possible by the creation of the internet. Internet telephony software essentially provides free telephone calls anywhere in the world One of the fastest- growing forms of internet communication is instant messaging, or also known as IM. An IM communications service enables you to create a private chat room with another individual in order to communicate in real-time over the internet. One of the reasons that IM has become so popular is because, unlike e-mails, if a person wants to reach another individual and they are come online, a message appears instantly in a window on their screen. IM is growing in popularity in the business world. Employees of a company can have instant access to managers and co-workers in different offices and can reduce the need to place phone calls when information is required immediately. IM can save time for employees and can reduce the amount of money a business spends on communication. Interviews can even be conducted online through video conferencing giving the same effects as real life interviews. Video conferencing is a conference between two or more participants at different sites by using computer networks to transmit audio and video data. Each participant has a video camera, microphone and speakers connected on his or her computer. As they speak, their voices are delivered to each other and whatever images appear in from of the video camera appear in a window in the other participants monitor. Advertising on the World Wide Web is a form of support for expressed purpose of delivering marketing messages to attract customers. It is expected to be the most effective form of advertising. Companies can reach a wide audience for a small fraction of traditional advertising budgets. This allows customers to research and purchase products and services at their own convenience. Social Impact The internet has enabled completely new forms of social interaction, activities, and organizing thanks to its basic features. Social networking websites such as Facebook, Myspace, and Friendster have created new ways to socialize and interact. These sites allow users to add information to pages, to add pictures, common interests and to connect with others. There are also sites that allow people to view videos and photographs. An example of this is YouTube. The internet also provides an area of leisure activity such as multiplayer gaming. This creates communities where people of all ages and origins take pleasure in the world of multiplayer games. Many people also use the Internet to access and download music, movies and other things for their enjoyment. In addition, the World Wide Web is used by many people to access news, to check the weather and sports reports, and to plan and book vacations. Selling The internet can also be used to sell products. A major advantage of selling via internet is the ability to reach anyone. You can reach customers that speak different languages. This is possible due to the fact that the language carrier is removed and translation software is used. When using the internet to sell products or services, one can operate from any computer in the world. Selling without the internet limits one to operate only from a fixed place. When selling via internet, one may take advantage of interactive and multimedia channels. These allow for immediate response time. One also has the option to remain anonymous which allows for privacy which would not normally have outside the internet. Having a product on sale to the public 24/7 is an incredible benefit of the internet. Center of learning With the internet you can learn to do anything or perfect a skill you already have. There are many websites where you can see an instructional video or read step by step on how to do whatever it is you would like. http://www.webopedia.com/DidYouKnow/Internet/2005/internet_communications.asp http://en.wikipedia.org/wiki/Online_advertising http://en.wikipedia.org/wiki/Internet#Modern_uses http://ezinearticles.com/?The-Advantage-of-Selling-via-Internetid=503987 Question 4: (A) Pipelining is a particularly effective way of organizing parallel activity in a computer system. The basic idea is very simple. A set of data processing elements connected in series, so that the output of one element is the input of the next one. The elements of a pipeline are often performed in parallel or in time-sliced fashion. It is divided in stages. Each stage completes a part of an instruction in parallel. The stages are connected to form a pipe. Instructions enter one end of the pipe, progress through the stages, and exit at the other end. http://www.cs.iastate.edu/~prabhu/Tutorial/PIPELINE/pipe_title.html http://en.wikipedia.org/wiki/Pipeline_(computing) (B) The system clock synchronizes the tasks in a computer, like loading date before manipulating it. The system clock is a circuit that sends out a continuous stream of precise high and low pulses that are all exactly the same length. Every modern PC has multiple system clocks. Each of these vibrates at a specific frequency, normally measured in MHz http://library.thinkquest.org/3114/clock.html (c) Parallel processing is the ability to carry out multiple operations or tasks simultaneously. Parallel processing makes programs run faster because there are more engines running it. With the help of parallel processing, a number of computers can be performed at once at a shorter rate. Question 2: Windows 98 is a widely-installed product in Microsofts evolution of the Windows operating system for personal computers. It has many features that has enhanced its growth. Multiple Monitors: Windows 98 now supports multiple monitors. Multiple monitors is a device for typical home and business use, but is an vital requirement for professional content creation. It is common to have all the software such as page layout, pre-press, illustration, animation and other graphics work on one screen and the artwork in progress on a screen by itself. It is frequent to have music and video on one complete monitor for each source and destination in use. Web integration: The windows 98 includes all of the improvements from windows desktop update, an internet explorer 4 components, desk bands, channels, ability to minimize foreground windows, single click launching, back and forward navigation buttons, favourites, and address bar in windows explorer. With active desktop, users can view and access desktop objects online as well as local files and applications. http://www.wisegeek.com/what-is-parallel-processing.htm http://www.ehow.com/facts_5022394_definition-disk-defragmenter.html#ixzz12DCrJMVS http://www.ehow.com/facts_5763189_definition-disk-cleanup_.html Read more: What Is the Definition of Disk Cleanup? | eHow.com http://www.ehow.com/facts_5763189_definition-disk-cleanup_.html#ixzz12DAeD6oh Read more: What Is the Definition of Disk Cleanup? | eHow.com http://www.ehow.com/facts_5763189_definition-disk-cleanup_.html#ixzz12DAHJFjy Read more: What Is the Definition of Disk Cleanup? | eHow.com http://www.ehow.com/facts_5763189_definition-disk-cleanup_.html#ixzz12D9VQkGm

The Impact of the Media on Body Image :: Media

Introduction In the recent decades, with the improvement of the living standard, people have been paying more attention to their own physical appearance. For example, when a person faces to a mirror, he or she will think about if his or her height, weight, body shape even the hair style are beautiful in nowadays’ society. Another example is many grandparents think their obese grandchildren are healthy, but a large number of adolescents themselves think as thin as fashion models are healthy. Obviously, different people have different body image in mind. In my view, the different culture backgrounds, genders, age groups or living environments all can cause different body images. This article will talk about how does the media impact people’s body image and some previous studies in body image will be shown. Literature review Media has become the main way for people to get information no matter is the ancient story or the latest news. However, the negative impact also comes out. For example, according to a meta-analysis of 25studies from 1979-2001 shows that people’s body images felt more positive after seeing a fat media image than viewing a thin media image(Groesz,L.,&Murnen,2007). Thus, the researcher sum up that the slender image can let people feel satisfaction. As a result, mare and more social or psychological researcher want to study that how the media influences people’s thinking and use the satisfaction to describe the measure of body image. Previous study one( body image study in adolescents) The researcher Hill, G.J. who is the assistant professor of Texas Christian University had a study focus on two main objects. First, to determine media images influence the body image among the collage students. Second, to find if the media effect collage students’ body satisfaction(Hill,G.J.,2009). According to him, the abilitiesof people realise body satisfaction and health behavior,are influenced by mass media images is very important for family and consumer sciences professionals to understand. In this study, there are 184 students who comes from a private university were attended this survey. The average age of student is 21. Both of the male (42%) and female (58%) students were given two sections which were the powerpoint presentation about the weighu management was developed and the questionnaires after the presentation. Firstly, these 184 students were randomly assigned to control and experimental groups. The presentation gave the introduction about achievinh h ealth weight, improving eating habits even the food guide pyramid.

Hollywood - Lies and Misrepresentations :: Film Movies

Hollywood - Lies and Misrepresentations In Hollywood, many filmmakers portray a distorted view of the Internet. Filmmakers do this by giving out misinformation on topics (i.e. Sharks-Jaws, Internet-The Net) that the public knows little about. When people know little about a specific topic, they begin to fear that issue. People fear the movie because they shut down their brain and tune into their senses, completely letting go of common knowledge. The public does not like to think about the movie. Not only does the filmmaker present the public with deceitful lies but they also capitalize on the net as a central problem, which is another regard to the misrepresentation of the Internet. The Internet is fraudulently represented in movies, such as The Net. Movie producers tap into the emotional fears of the public and stretch the fears of the viewers as far as they will go, stopping just before they access the peoples more rational train of thought. The Net, a popular movie in 1995, compels people to think that what is happening in this movie, could just as well happen to them. When the movie The Net came out in 1995, the public was just receiving the basic e-mail accounts. The common person had little to no knowledge of the Internet. As soon as filmmakers found this piece of information, they seized the idea of the Internet, a dangerous place for all. The producers gave the idea that if people type out where they live, what their telephone number is, etc., just to get their e-mail account, the government will track them and quite possibly, be running for their life. The public felt this way because of the misconceptions of where their info is going. They thought that while they were typing it out, it would be presented for many other people to see. Another example of this would be the movie Jaws. Before the movie came out most of the population had little facts about sharks. So naturally, when people do not know much about a certain object, movie producers have plenty of room to play with peoples emotions. Filmmakers love to capitalize upon the Net, however the Internet is not the central problem. The Net is not one thing. Its like asking: Are women comfortable in bars? Thats a silly question. Which women? Which bar? (Bruckman-171) I believe in Bruckmans statement about how that is a silly question.

The Road Not Taken Essay -- Poetry Robert Frost essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  In analyzing the poem 'The Road Not Taken'; by Robert Frost, it represents 'the classic choice of a moment and a lifetime.';(pg 129) He relies much on the reflections of nature to convey his theme. However, this poem seems to be in essence very simple but opens the door for many interpretations. In using a simple fork in a road, Frost writes much to symbolize life and choices in which one will make. Frost uses unique ability to see an ordinary, everyday activity to portray such a theme. By using such simple endeavors, Frost reaches his audience on a more personal level. However, it is only one's past, present and the attitude with which he or she looks upon the future that determines the shade of light in which the poem will be seen. (pg 621) There is never a straight path for one to follow on life's journey. By using two paths in which to choose from, Frost leaves one to realize that everyone must travel and will reach a point of decision. With stating 'And sorry I could not travel both,'; Frost shows the point in which one will choose because there is only one path in which one may travel. It is most difficult to make a decision on each appealing path because everyone will always seem to question 'what could I or could I not miss out on?'; The fact he is sorry he is sorry he cannot travel, or choose, both paves the way for regret. This will often be reflected upon by an individual in which saying ' what could have been'; leads one to dwelling over the choice of road in which they did not take. In knowing that each one may be influenced in many directions, Frost clearly implies 'And be one traveler, long I stood.'; No matter how each of us may be influenced by family or various sources, there is only 'one traveler'; that will be affected by any decision and there is quite a lengthy thought process involved. Regardless of any outside influence there is only one to be involved and truly affected, as does any choice in life. In somewhat of an attempt to make a decision each person wants to carefully examine the unknown. In using sort of a checks and balances a person would weigh out the risk factor to be involved. Frost uses the line, 'And looked down one as far as I could'; to portray an involved examination. The strain used in 'as far as I could'; symbolizes somewhat of a unknown content of where the path may lead. No matter what one knows... ...o sharply limited.';(pg 496) One would have to agree with his point, because everyone has had to make difficult unalterable decisions of which the outcome could not be foreseen. The narrator must choose between two 'fair'; roads, of which he cannot see the endpoints. Wandering between the two, he finally decides to take the road 'less traveled by.'; Yet, like most people, he later sighs with regret thinking of what he might have missed on the unexplored road. Above all, 'The Road Not Taken'; can truly be interpreted through much symbolism as a clear-sighted representation of two fair choices. The two roads in the poem, although, 'diverging,'; lead in different directions. At the beginning they appear to be somewhat similar, but is apparent that miles away they will grow farther and farther away from each other. Similar to many choices faced in life. It is impossible to foresee the consequences of most major decisions we make and it is often necessary to make these decisions based on a little more than examining which choice 'wanted wear.'; In the end, we look back upon the choices we have made and like the narrator 'sigh,'; observing that they have made 'all the difference.'

When the singer show up or release new album, you always spend your money to buy it every time they release. If they release 100 different new album, Would you buy all this album?

From classical to jazz, pop, rock, R&B, hip hop or even devotional songs, music affect different people in many different way. That is why we can see nowadays some people who are enthusiastic about music even attribute themselves and their talents into music professions. Music touches our soul and allows us to express different moods and emotions. Therefore, music has many roles that affect everyone’s life. Listening to certain songs usually triggers to certain emotions linked to that song. As for me, I would listen to various sorts of songs to cheer my mood up. And seriously, life without music would be very dull. Have you ever heard of the saying, â€Å"hooked on the feeling? ’’. Well, it really happens. For example, during festive seasons like Christmas, many people will put on Christmas songs because this will help them to stay on the state of euphoria all month long and bring back their childhood memories of Christmas. Therefore, music also plays a very crucial ole in overall development of an individual. It can take the mind and body to do spontaneous things either good or bad, depends on the type of music a person is listening to and it message contains. For instance, when someone is listening to sad songs related to their love or life, the listener will be highly in touch with that song connected with their emotions. Likewise, when another person is listening to a heavy metal songs, they might inhibited violated act or aggressive behavior as rock songs bring about rebellion and agitation influence. However, for some people, listening to this type of songs is their way of expressing anger and relieve from pain. Well, it’s actually depends on that person himself on how they interact and influence by the music.

Nurse Practitioner Scope of Practice in the United States

Nurse Practitioners are registered nurses who are outstandingly recognized for providing primary care and treating acute and chronic illness and diseases. They acquired practiced skills and experience through advance education and medical training, and are authorized to serve as health and medical care resources and interdisciplinary consultants for diverse populations during health and illness. Nurse Practitioners may be generalists, like family nurse practitioners, or specialists whose areas of expertise include pediatrics, geriatrics, and psychiatry.Nurse Practitioners render a wide range of different types of preventive and clinical services as authorized by a state's Nurse Practice Act that vary from state-to-state in which some allow independent practice for nurse practitioners. In the United States, the state from which a nurse practitioner is practicing gives the nurse practitioner’s license being certified by the American Nurses Credentialing Center (ANCC). Since the profession is regulated by the state, the extended care-giving role played by Nurse Practitioners varies. Nurse practitioners in the community may be engaged in health maintenance organizations, home health care agencies, public health departments, school or college clinics, and physician’s offices, to mention a few.With increasing demand for primary care services to underserved groups and communities, nurse practitioners are successfully qualified for rendering such service, being fully equipped with appropriate knowledge and training. Standards for practice developed by the American Academy of Nurse Practitioners (1993) provide the specific activities that a nurse practitioner can perform and govern the services granted.In general, regardless of specialty, the scope of services practiced by nurse practitioners is divided into three categories. The first category covers the assessment of health status. This includes activities such as obtaining medical and health record of a n individual, performing nursing assessments, and conducting physical examination on patients. Nurse practitioners also perform preventive screening procedures based on the patient’s age and history. Such screening includes those for hearing, sight, and cancer. Identification of medical health risks and requirements is also under the scope of practice of this profession.The second category is the application of suitable diagnosis based on previous examinations and clinical findings. They execute and interpret diagnostic studies such as routine laboratory tests, EKGs and X-rays. Diagnosing, treating, evaluating, and managing minor and common and acute and stable illness and diseases such as injuries, diabetes, and high blood pressure are being employed by nurse practitioners. Also, with proper training or with supervision, they are also allowed to perform minor surgeries and procedures and may be First Assistants in the OR.Central to the care provided by nurse practitioners ar e the conditions of the patients and the further effect of illness on the lives of the patients and the patients’ relatives. Thus, supportive counseling and educating patients regarding their health behaviors stressing out health promotion and citing preventive measures on illness and diseases are also under the practice of nurse practitioners. Providing prenatal care, conducting well-child screenings and immunizations, prescribing rehabilitation treatments and medications, though limited in some states, are also being practiced. All of these fall under the third category and can be summarized as the management of the case.This further identifies the needs of individual, family or community the assessment and interpretation of data collected.   Evaluation and execution of plan of care are also being stressed in the practice of such profession. Nurse practitioners also establish collaborative working relationship with physicians to provide comprehensive care and refer patien ts to other health professionals as needed to meet the appropriate health and medical goals.Nurse practitioners with specialization may include other specific activities in their scope of practice in line with their acquired specialty to further serve the target population. For pedriatric nurse practitioner, for instance, one may include the analysis of factors that may affect the child’s growth and development. Studies relating to abnormal and normal development in relation to anatomical, physiological, motor, cognitive, and social behavior of the child may be included in his scope of practice. Women’s health care nurse practitioner may perform fertility counseling and infertility management and may also give prescription and management of birth control pills and diaphragms or provide family planning services.To further improve the scope of practice, there are nurse practitioners that take advance training for certain clinical procedures. These procedures which can be accomplished by nurse practitioners with effective training which depends on previous experience and practice limitations of individual state Nurse Practice Acts.The continuing progress to cope with changing health care needs of the society is the responsibility of the nurse practitioners. They unite the role of being a care resource person, counselor and educator, researcher and administrator especially in the field of primary health care. Members of such profession are liable for the expansion and improvement of the practice of such profession and this can be achieved through involvement and active participation in professional health care organizations and their activities as they ensure that the standards on the scope of practice for nurse practitioners are maintained.ReferencesKozier B., et al.

Defining Nurse Practitioner Scope of Practice:

Bad Teachers

The poor teaching habits of teachers shows greatly in the way students learn. It causes students to become unmotivated, drop out, and it also increases their chances of going to prison. In the documentary â€Å"Waiting for Superman† states that because of bad teachers students are more likely to fail and drop out of school. In the documentary they showed that bad teachers just sat in class and slept or did not teach but since they had tenure they could not be fired without going through paperwork and courts. The students are what suffer the most because of this.Bad teachers are the main cause of failing grades, unmotivated students, and the increase of high school dropouts in prisons. The lackadaisical mentors cause students to hate what they are learning and not want to learn. It also causes them to not go to class and start to fail. The documentary stated that careless teachers only cover fifty percent of the material while good teachers can cover three times that. In my hig h school we had a teacher who didn’t make class worth coming to. She would give notes and handouts and sit at her desk the whole class.It made it really hard for me to learn, or want to learn. I basically had to teach myself algebra because she wouldn’t. Then when the next year came along I had no idea what we were learning. My lazy teacher ruined mathematics for me. When students become unmotivated they start to fail their classes because they think they can’t learn, or they are stupid, when in reality it is the teachers fault. Failing students can become depressed or not care what happens to their future but they don’t realize that with failing grades colleges won’t accept you, and if you do get into a college you won’t know the material.Bad teachers are the cause of unmotivated students because when students don’t have fun learning they won’t want to learn. When students don’t want to learn it ruins their chances of g etting good grades in that class and also other classes. Prisons are filled with high school dropouts because they can’t get a good job without a diploma. To make extra money they may sell drugs or rob people and when they get caught they go to jail. I personally believe that if the school system was fixed there wouldn’t be as much crime because people would want to learn and go to college to make good money. The cause of all of this goes back to the teachers. Waiting for Superman† shows the statistics of high school dropouts to inmates in prison and they were very high. The school system needs revised so that students can get a better education and be able to succeed in life. Until we can do this the bad teachers will continue to ruin students’ education making them not want to learn or end up dropping out. The documentary â€Å"Waiting for Superman† was very educational of how schools cannot change due to tenure and unions. I believe that bad teac hers will never go away until they start to notice that this generation is failing because of the education we need but did not receive.
