System Software, Development and Application Essay Example for Free

System Software, Development and Application Essay In the aspect of computer technology, several elements and factors must be critically considered because of their impact and relevance on the computing capacity, efficiency and effectivity in performing the tasks relevant to the public user. The basics among these important computer specifications are the processing capacity, memory storage and computing speed in terms of handling the relevant tasks, softwares, and programs needed by its users. Determining these factors requires software and hardware knowledge to determine their most intricate and critical specification as these factors are relevant to the processing ability of the computer unit. In analyzing the performance value of a specific computer, its ability to process important softwares such as for encoding purposes, internet surfing, image and file viewer and other must be considered. In addition to these, the personal preferences and usage intention of the user must also be considered in determining which specific specification or manufacturer’s brand is effective for such need. Considering the present brands of computer units, there are actually several financial options to choose from in the acquisition of a computer unit that is suitable for the user’s needs. In this paper, actual computer units and brands will be consider and analyze to determine their effectiveness under the disparity of the most and least expensive in the market. In the category of the most expensive, the latest brand of Alienware computer brands namely the Aurora ALX reign top in the list. The specifications of this brand loudly state the reason for this nature as the unit incorporates in its system the latest and highly advanced technology in the present information technology world. On the analysis of its hard disk capacity (storage) as the comparison medium, this unit to hold 128GB storage capacity, which can be further upgraded because of its 4 drives capacity slot. This extends the memory storage capability of this unit to 512GB of storage space. On the other hand, the least expensive brand comes from the most economical manufacturing brand namely the Dell Optiplex GX270, which is less than the quarter of the price of its price range counterpart. This unit offers what is considered storage capacity of 40 GB storage space. Indeed, based on the comparison of these two actual computer brands, price of the unit is commensurable to the capacity it has including the storage space it offers for their users. Storage space is indeed important in the computer unit, their efficiency, performance vale, and effectiveness in terms of their capable tasks and responsibility. However, considering the basic needs of the encoding, internet surfing, file and picture viewing, large storage space is not much of a necessity for these particular tasks. On further analysis and brand comparison, this paper will consider several actual softwares that are needed for certain computing tasks such as Microsoft Office Home 2007 for encoding needs, Adobe Photoshop CS Edition for file and photo viewing, and Netscape Navigator for internet surfing purposes. For the Microsoft Office Home 2007, the recommended storage capacity to use this software is 1.5GB. For the Adobe Photoshop CS Edition, it is necessary to have at least 280MB of available hard disk space. Finally, the Netscape Navigator requires 100 MB of free storage space for its effective function. Thus, consider this top and among the most required computer application softwares, the established least expensive computer unit in the previous comparison appears to be sufficient, with its basic storage capacity, to handle the common tasks of encoding, surfing, and file viewing for its users. Because of this, even the least expensive computer brand in the present is still within the recommended units particularly for users who only need to perform basic computer tasks to aid their actual tasks and responsibilities. In general, each computer units has their own system specifications determining whether they are among the fastest or more efficient computer model or just within the basic range. This system specification determines much the specific economic value of price of the said computer model, as they tend to be commensurable to the performance value of the unit. However, considering the price efficiency and performance capacity of those considered to be among the cheapest brand, these computer units namely the Dell Optiplex GX270 and the other models falling in its category are still effective enough to handle the basic computer tasks in the present society. As such, price and high-end specification are not the main standards in weighing the relevance factor of each computer brands but instead, their performance value and actual significance to the needs of their users in terms of computing tasks and operations

Alzheimers Disease Essay -- Alzheimers Disease Essays

â€Å"Alzheimer’s disease is a form of dementia that gets worse over time. It leads to nerve cell death, and tissue loss throughout the brain. Over time, the brain shrinks dramatically, affecting nearly all its functions. It gradually destroys a person's memory and ability to learn and carry out daily activities such as talking, eating, and going to the bathroom† (What Is Alzheimer’s). Early symptoms include personality changes, memory impairment, problems with language, decision-making ability, judgment, and personality. Alzheimer’s was named after Dr. Alois Alzheimer. In 1906, Dr. Alzheimer noticed changes in the brain tissue of a woman who died of an unusual mental illness. After she died, he examined her and found plaques and tangles in her brain which are the two main features of Alzheimer’s. â€Å"Patients with Alzheimer’s often die earlier than normal, although a patient may live anywhere from 3-20 years after diagnosis.† Death often occurs from an infection or a failure of other body systems. â€Å"Early diagnosis relies largely on documenting mental decline. Biomarkers are reliable predictors and indicators of a disease process.† Alzheimer’s begins as early as 10 to 20 years before any problems are evident. It develops in your 30s, 40s, 50s, but usually after age 60. As many as 5.1 million Americans may have this disease. â€Å"There is no specific test today that confirms you have Alzheimer’s disease. Your doctor will make a judgment about whether Alzheimer's is the most likely cause of your symptoms based on the information you provide and results of various tests that can help clarify the diagnosis.† Doctors typically rely on physical and neurological exams to check your reflexes and sense of touch and sight, lab t... ... Researchers are looking for new treatments to alter the course of the disease and improve the quality of life for people with dementia. Works Cited 1.

Effects of Alcohol Consumption to the Cognitive Function of a Person

Excessive alcohol intake has a great impact on the cognitive function of a person. It leads to a person to have a poor cognitive function. Which can be affected the persons perception, attention, memory, motor skills, language, visual and spatial processing. To some extent, study indicates that high level of impulsivity in alcohol consumptions of a person has an effect on the frontal lobe related to their behavioral problem (Lyvers et. al. ). Furthermore, alcohol intoxication causes disruption of prefrontal cortical functioning and thereby impairs executive cognitive performance.As executive cognitive ability is concerned this is the prefrontal cortex, which is responsible for problem solving, cognitive flexibility, planning, organization, abstract reasoning and social conduct. A person who is in inebriated situation is more likely to do risky, impulsive behavior such as unprotected sex, violence and drunk driving. In some situation, severe alcoholics’ gets complication, serio us organic cerebral impairment; it is the common complication occurring in about 10 percent of patient (Horvath 1975).Lishman 1981; American Psychiatric Association 1987, the diverse signs of severe brain dysfunction that persist after cessation of alcohol consumption have been conceptualize in terms of two organic mental disorders: alcohol amnestic disorder (memory disorder) and dementia associated with alcoholism. Alcohol amnestic disorder, commonly called Korsakoff’s psychosis or Wernicke- Korsakoff syndrome, it is characterized by short term memory, impairments and behavioral changes that occur without clouding of consciousness or general loss of intellectual abilities.Dementia associated with alcoholism consist of global loss of intellectual abilities with an impairment in memory function together disturbance(s) of abstract thinking, judgment, other higher cortical function or personality change without a clouding of consciousness. These two mental disorders are also cau se by a severe deficiency of  Thiamine  (vitamin B1) and are often precipitated by a sudden influx of glucose. A number of things have been shown to lead to a severe enough thiamine deficiency to trigger wet brain.Wet brain or Wernicke-Korsakoff Syndrome  has a sudden onset–it is not something which happens gradually over time. The first stage of wet brain is called Wernicke's encephalopathy. When there is a sudden influx of glucose in a brain which is deprived of thiamine the brain cells begin to die. This is because the chemical reactions which supply these brain cells with energy for life use thiamine to turn glucose into energy in a chemical process called the Krebs cycle.When there is an influx of glucose and no thiamine to help metabolize it, these brain cells burn out like a car engine running on high octane gasoline at high speed with no oil. The brain cells which die first are the ones which require the most thiamine to function. These brain cells are located a round the middle of the brain and are the brain cells which are associated with memory and muscular movement. The brain cells of the cerebellum, which controls balance, are also affected.Korsakoff's syndrome includes loss of past memories, inability to learn new things, confabulation (remembering things which never happened), lack of coordination and unsteady gait, and in severe cases dementia. These are the possible reaction to a person who takes excessive alcohol consumptions. More evident in explaining the effect of excessive intake of alcohol in a person’s cognitive function is that he/she will experienced less adept at certain learning tests and visual- spatial integration. Likewise it cause premature aging (Tarter and Edwards, 1986) and it is still under active investigation.In addition, it has long been an established fact that actively drinking, alcohol dependent subjects have smaller brain volumes than normal control subjects who do not drink alcohol. Thus, early res earchers assumed that this was because alcohol killed the brain cells of alcohol dependent subjects, but other research disapproves this hypothesis but it could be partially true unless there has been brain damage as a result of  liver failure  or  thiamine deficiency, the majority of brain cells of heavy drinkers are intact even though the brain has shrunk.Meanwhile, in some study stated that alcohol consumption in a moderate mode has an effect to help a person to decrease the incidence of having diabetes. Likewise, it can help to preserve brain vasculature prevents sub-clinical strokes and could result in better cognition function. But drinking too much of alcohol leads to have poor cognitive function that causes to a person to have brain damage. Some research shows that alcohol adversely affects the brain.When health professionals encounter patients who are having cognitive difficulties, such as impaired memory or reasoning ability, alcohol use may be the cause of the probl em. The human brain consists of white cells and gray cells. The gray cells are responsible for thinking and feeling and decisions–they correspond to the Central Processing Unit (CPU) of the computer. The white cells are like the cables of the computer which connect the keyboard and the monitor to the CPU.Jensen and Pakkenberg (1993) did brain cell counts which compared the number of cells in the brains of heavy drinkers with those of non-drinkers. They found out that the number of gray cells was the same in both the heavy drinkers and the non-drinkers. However, there were fewer white brain cells in the brains of the drinkers which imply that alcohol kills a white brain cell that is responsible to the connection to pass the message or transaction of the brain to connect with the feeling and decision making of a person.Hence, excessive alcohol intake disrupts the connection or breaks the normal function of the brain to react and to have a better cognitive function. Moreover, Ge orge Fein (2009) discovered that there was one part of the brain in the parietal lobe–which is associated with spatial processing–where alcohol kills gray cells. Fein claims that this explains why even after alcohol dependent subjects regain use of all their other cognitive functions they still seem to have difficulties with spatial processing.Parker et al. (1983) stated that there is significant decrease in test performance have been found for people whose self-reported alcohol consumption was in the range of what was considered social drinking. They found it out when they conducted a certain neuropsychological tests, the results of one general population study (Bergman et al. 1983). Those people were not clinically impaired; they only exhibited certain performance deficits that correlated with alcohol consumption.Parsons (1986) concluded that data on the relationship of cognitive impairment to amount of alcohol consumed by social drinkers are inconclusive but has the chance to have similar correlation. There is some evidence that both the amount of brain shrinkage and the amount of cognitive deficit are dependent on the quantity of alcohol consumed and the number of years of heavy drinking. Thus, it only proves that there is an adversely effect on the cognitive function of a person in drinking too much of it. Hence, there is no good effect on the brain or body function of a person.

A Plan of Action for Success in High School or College

Strategic plans are tools that many organizations use to keep themselves successful and on track. A strategic plan is a roadmap for success. You can use the same sort of plan to establish a route to academic success in high school or college. The plan may involve a strategy for achieving success in a single year of high school or for your entire educational experience. Ready to get started? Most basic strategic plans contain these five elements: Mission StatementGoalsStrategy or MethodsObjectivesEvaluation and Review Create a Mission Statement   You will kick off your roadmap for success by determining your overall mission for the year (or four years) of education. Your dreams will be put into words in a written statement called a mission statement. You need to decide ahead of time what youd like to accomplish, then write a paragraph to define this goal. This statement can be a little vague, but thats only because you need to think big at the beginning stage. (Youll see that you should go into detail a little later.) The statement should spell out an overall target that would enable you to reach your highest potential. Your statement should be personalized: it should fit your individual personality as well as your special dreams for the future. As you craft a mission statement, consider how you are special and different, and think about how you can tap in to your special talents and strengths to achieve your target. You might even come up with a motto. Sample Mission Statement Stephanie Baker is a young woman determined to graduate in the top two percent of her class. Her mission is to use the gregarious, open side of her personality to build positive relationships, and to tap in to her studious side to keep her grades high. She will manage her time and her relationships to establish a professional reputation by building on her social skills and her study skills. Stephanies motto is: Enrich your life and reach for the stars. Select the Goals   Goals are general statements that identify some benchmarks youll need to accomplish in order to meet your mission. Most likely you will need to address some possible stumbling blocks you may face on your journey. As in business, you need to recognize any weaknesses and create a defensive strategy in addition to your offensive strategy. Offensive Goals: I will set aside specific times to do homework.I will build relationships with teachers who write great recommendations! Defensive Goal: I will identify and eliminate time-wasting activities by half.I will manage relationships that involve drama and that threaten to drain my energy. Plan Strategies for Reaching Every Goal   Take a good look at the goals youve developed and come up with specifics for reaching them. If one of your goals is dedicating two hours a night to homework, a strategy for reaching that goal is to decide what else might interfere with that and plan around it. Be real when you examine your routine and your plans. For instance, if you are addicted to American Idol or So You Think You Can Dance, make plans to record your show(s) and also to keep others from spoiling the outcomes for you. See how this reflects reality? If you think something so frivolous as planning around a favorite show doesnt belong in a strategic plan, think again! In real life, some of the most popular reality shows consume four to ten hours of our time every week (watching and discussing). This is just the sort of hidden roadblock that can bring you down! Create Objectives   Objectives are clear and measurable statements, as opposed to goals, which are essential but indistinct. They are specific acts, tools, numbers, and things that provide concrete evidence of success. If you do these, youll know youre on track. If you dont carry out your objectives, you can bet youre not reaching your goals. You can kid yourself about many things in your strategic plan, but not objectives. Thats why theyre important. Sample Objectives Buy a planner and write in it every day.Sign a homework contract.Secure a device for recording my favorite shows.Take a learning style exam to determine my best learning style. Evaluate Your Progress   Its not easy to write a good strategic plan on your first try. This is actually a skill that some organizations find difficult. Every strategic plan should have in place a system for an occasional reality check. If you find, halfway through the year, that you are not meeting goals; or if you discover a few weeks into your mission that your objectives arent helping you to get where you need to be, it may be time to revisit your strategic plan and hone it.
