Similarities and differences of linux and microsoft windows operating system

Similarities and differences of linux and microsoft windows operating system When it comes to operating systems there are two main systems used for the PC, Linux and Microsoft Windows. They are both similar as they are different. Linux and Windows are both operating systems which are interfaces that are responsible for the activities and sharing of the computer. They act like a host for applications that run on the computer. Both have graphical user interfaces. Graphical user interfaces are a type of user interface that allows people to use programs in more ways than just typing. They both include web browsers that are applications for presenting information on the Internet. Linuxs browser is Opera and the Internet Explorer is the browser for Windows. These operating systems also have differences with Linux once installed a mouse is no longer needed however a mouse is necessary with Windows. Windows 7 costs approximately $200 while Linux is free. Linux file formats can be accessed in many different ways and Windows makes it more difficult for the user to find their data. Windows is based on DOS, and Linux is based on UNIX. Linux is very customizable for customers. Windows boots off of a primary partition. Linux can boot either from a primary or a logical partition. Both Intel and AMD are both microprocessor. They incorporate most or all the funtions of the CPU, on one integrated circuit. Most of the new computers built today have either AMD or Intel processors. AMD and Intel have the most popular micro processing chip in the computer market. Both chips support a lot of cross compatible hardware. When it comes to processors AMD (Advanced Micro Devices) and Intel (previously known as Integrated Electronics Corporation) are the biggest names. Intel is focused on building fast and stronger microprocessors. The company really took off with the release of their pentium series. Even though Intel still holds top honors AMD, on some occasion, exceeds Intel. AMD offers more value for your money. They dont have the fastest processors however it doesnt cost much to buy one. Intel processors usually have double the amount of L2 cache. Finally AMD processors have integrated memory controllers and Intel does not have this ability. AC Power (Alternating current), is power in an electric circuit. The AC power controls the rate of the flow of energy past a given point of the circuit. DC power (Direct current) is the unidirectional flow of an electric charge. AC and DC are both methods in which electrons are moved along a wire, causing current. Both AC and DC employ magnets to repel electrons One difference between AC and DC power is that AC is an alternating current that flows in both directions and DC is a current that flows in only one direction. The wires outside peoples homes are connected at two ends to AC generators while DC is found in devices such as batteries and solar cells. DC power doesnt need a live wire. The Binary number system and the Decimal number system all use single digits. Every combination of numbers identifies certain things. The numbers can be joined to make multiple combinations. Different combinations can be used to identify specific things. Both systems can be used in everyday life. A Binary number system is a method of representing numbers in which only the digits 0 and 1 are used. Every number in the binary system is a combination that only has two digits. A Decimal system describes a system that has ten possible digits. All the numbers used in the decimal system are the combination of the digits 0-9. All of the numbers in the decimal system are a combination of ten digits. Magnetic media is a term in engineering that refers to the storage of data. It uses different patterns of magnetization to store data, which is a form of non-volatile memory. Optical media is a storage media that can hold content in a digital form. It can be written and read by a laser. These media usually include all variations of CDs and DVDs as well as optical jukeboxes and auto chargers. An optical disk capacity ranges up to 6 gigabytes of content as compared to 1.44 megabytes. One optical disk holds about as much space as 500 floppy disks. Optical media usually lasts up to seven times longer than storage media. Magnetic media is very easy to re-write on. Optical media is easier to handle and transport and usually costs a lot less due to its simplicity. Magnetic storage is usually very sensitive to a magnetic field. Storage can be ruined when placed by a magnet while optical media is unaffected. Most computers that are in the market today do not even have an input for a magnetic storage device. It is outdated. Both magnetic media and optical media are used as storage devices. Storage devices are used for recording information. A storage device can hold information, process information or both. This provides one of the core functions of the computer. They are both portable and do not take up a lot of room.

Performance Appraisal Research Proposal Essays and Term Papers

The Impact of Workplace Absenteeism on Organizational Performance Introduction Many organizations recognized the employees’ performances. Performances expected coming from the employees are affected by their participation and being present in their roles and responsibilities. However, manages are forced to find an ideal remedy in the habitual tardiness or absenteeism of the employees. This is because, the organizations realized an unprofitable investment if there is any unscheduled absents.Furthermore, there is a reduction of the total productivity of the manpower that might affect the entire operation of the business. Background of study Absenteeism is the result of the different employee behaviors. Most of the workers are experiencing high stress or improperly compensated that reflects in their absences (McLaughlin Young Group, 2007). Statement of the problem The cost of absenteeism is greater when lost productivity, temporary labor and dissatisfied customers are considered. Almost all the employees have their absences more than five times per year and are coming from different sectors (McLean, 2005). The growing numbers of employees having the same problems on attendance will manifests in their ability to contribute in the total growth of their own career and in the organization. Leaders believe that if they did not create a significant solution to this problem, more and more employees will do the same as it is became part of theorganizational culture. However, what are the real-life impacts of workplace absenteeism on the organizational performance?Literature Review Absenteeism occurs when the employees are not present at work when they are scheduled to be there. It can be divided into voluntary or involuntary absenteeism. Involuntary absence is viewed to be beyond the employee’s immediate control; legitimate reasons like personal illness, accidents or family emergencies. Voluntary absence is under the direct control of the employee which can o ften be traced back to other factors such as a poor work environment, job dissatisfaction and other issues.If such absences become excessive, they can have a seriously adverse impact on a company’s operations and, ultimately, its profitability (Pillay, 2009). From the previous surveys, the experts discovered that absenteeism results most often from health and personal reasons, but the fact is that only about a third of absences are caused by personal illness. The survey shows that more than half of unscheduled absences are justified by family issues, personal needs, stress and an entitlement mentality (McLean, 2005).If all of the reasons in the absences of the employees are on thehealth issues, therefore, the absenteeism can be linked in the stress they gathered in the workplace. The occupational stress is one of the most significant workplace health hazards. The prolonged exposure of an employee to certainjob demands can lead to a variety of pathological outcomes that can be both short- and long-term effects on their emotional health such as emotional distress, depression and anxiety. Other employees might experience the various difficulties in family, financial, or physical health.All of the work-related stresses or problems that the employees can experience might result in their attendance. The negative effects of the increase in employee absence are their poor performances (McLaughlin Young Group, 2007). Objectives of the study The aim of the study is to identify the existence of absenteeism that can draw a link towards its impact on the organization and the employee’s performance. In order to achieve this aim, there are three objectives that should be considered.First is to identify the cause of the workplace absenteeism. Second is to find out the common type of workplace absenteeism. Third is to evaluate the costs that inherent in the workplace absenteeism and how they impact on the organizational performance. And fourth is to establish the mechanism for curbing the workplace absenteeism. Methodology The suggested method that can be use in the study is the use of survey and interview. In the first phase of the study, the survey will be conducted on the employees through the use of questionnaires.The material is in a Likert Scale form in which gives the details to the researcher/s on the perception of the employees on absenteeism and their behavior in their attendances. On the second part of the study, the interview will be conducted on the managers and/or supervisors, and even the HR manager, who can assess the behavior of the employees in their attendance and performance. Through the interview, the researcher/s can analyze the appropriate actions for the employees who are creating the trends of absenteeism and recognize the effectiveness of their mechanism to reduce the absenteeism in their workplace.

Down Syndrome The Common Genetic Condition Essay

Introduction: Down Syndrome affects many people, even those who don’t have it. Down syndrome is also called Trisomy 21. The term Down syndrome did not become the accepted term until the early 1970’s (â€Å"History of NADS†). Down syndrome is the most common genetic condition, almost 400,000 Americans have Down syndrome (â€Å"What Is Down Syndrome?†). When the 21st chromosome has an extra copy, full or partial, down syndrome will occur. With the extra genetic material it messes with the development physically and mentally. It also creates certain features connected with Down Syndrome. Some of the well known features are low muscle tone, small stature, upward slant to the eyes, and a single deep crease across the center of the palm (â€Å"What Is Down Syndrome?†). These features and their extent can vary from person to person, some may not even have any at all. One in every 691 babies born in the United States has Down syndrome, about 6,000 babi es are born with Down syndrome each year in the United States (â€Å"What Is Down Syndrome?†). Just like the physical features the medical problems associated with Down syndrome vary from person to person, some may need a lot while others may need little to none.

Drug Abuse Has Become A Real Problem - 1235 Words

Heroin In the world today, drug abuse has become a real problem. In the 1800s there was a drug called opium that was commonly used. Opium came from the poppy seed plant and became very popular here in America, starting in the west. There used to be opium dens where cowhands would stop and stay and smoke opium. From opium, along came the drug morphine. Morphine was derived from the drug opium and was also introduced in America in the 1800s. Morphine became a very popular pain killer in America during that time, and it still is today. During the Civil War is when people started to realize how addictive the morphine was. There was a huge morphine epidemic in America after the Civil War and doctors did not know how to treat it. In 1874,†¦show more content†¦Although heroin is illegal in the United States, the number of heroin addicts in the US is increasing. â€Å"According to the 2011 Survey on Drug Use and Health by the US Substance Abuse and Mental Health Administration, it is estimated that 607,000 persons per year used heroin in the years 2009-2011† (Anderson). A lot of people who try heroin for the first time have no idea what they are dealing with. The drug is so strong that if someone takes too much then they could easily overdose or even die on just the first time trying it. The age group that has increased the most on heroin abuse is young adults from the ages of nineteen to twenty-eight (Anderson). Although that is the age group affected most, there are still younger teenagers and older adults who have used heroin. Heroin can be taken many different ways. It can be injected, smoked, snorted, or just ingested like food. Many heroin users start off by either smoking or snorting it, but they begin to become tolerant to the high that it produces. The most common way of using heroin is by injecting it with a needle into your bloodstream. Out of all the ways to take heroin, injecting it has to greatest risk of lethal overdose. This is because of the large amounts of heroin that is going directly into the bloodstream (Nadelmann). There are a lot of different spots on the body that people can use to inject heroin. Some of the more common places are on the arms and legs. People can
