The Advantages And Disadvantages Of Using Linux Computer Science Essay

The Advantages And Disadvantages Of Using Linux Computer Science Essay Easy to use,Virus free,With boot camp you can run XP or Vista on your machine, and with Parallels you can run windows programs in OS XP. Performance: While there is some debate about which operating system performs better, in our experience both perform comparably in low-stress conditions however UNIX servers under high load (which is what is important) are superior to Windows. Price: Servers hosting your web site require operating systems and licenses just like everyone else. Windows 2003 and other related applications like SQL Server each cost a significant amount of money; on the other hand, Linux is a free operating system to download, install and operate. Windows hosting results in being a more expensive platform. Less viruses: Windows currently has over a hundred thousand known viruses, while Linux has less than a hundred. Linux also uses smart authorisation management , so it requires you to authorise any action that may potentially harm your computer by entering your password. That means you are less likely to be tricked into installing malware and running virus programs, simply because it wont let you. No crashes: Windows users will be familiar with the infamous blue screen of death that greets them whenever the system crashes. In contrast, Linux users have reported uptimes exceeding over a year, which means that their computers have been continuously running over a year without a single crash or reboot. Free software: Linux users can download free software from huge repositories containing thousands of free programs and applications, from games to music players to office productivity tools. Most of them serve as free alternatives to commercial software, the most popular ones being OpenOffice and Mozilla Firefox, which replace Microsoft Office and Internet Explorer respectively. Disadvantage: Easily gets virus and or spyware.Does not come with many useful software alrdy installed.Easlity disrupted by other programs. Interface: The traditional interface for the Unix operating system is command line based, and this command line shell interface may be hostile to the casual user. Unix was developed for use by programmers and serious computer users rather than casual users. A graphical user interface (GUI) is also available, but the traditional Unix interface is command line only. Special Commands: Commands required by the command line interface often make use of cryptic naming schemes, and do not give much information to notify a user of what they are doing. Many commands in the Unix interface require the use of special characters. Small, normally insignificant typos can have much greater effects and unexpected results on Unix machines. *The Advantages and Disadvantages of Using Microsoft Windows 2003 Advantage: Abundance of Features: Windows Server 2003 added an abundance of features over the previous Windows 2000 version, including a Volume Shadow copy service. If an administrator activates this feature on a drive, the system will periodically take snapshots of all the files on that drive. This enables deleted files to be recovered easier and can enable the option of recovering an older version of a file if some data got lost. In Setup mode, it also offers a Quick Format option where you can format a specific partition of a drive instead of having to do the entire drive at once, which saves a significant amount of time.

Outdated: Another disadvantage to Windows Server 2003 is that is was already made obsolete by Windows Server 2008 and then Windows Server 2008 R2. Any upgrades to the Server systems will be made off of those versions and not the 2003 option. The 2008 version features enhanced security features that make it more attractive for many businesses in the wake of ever-evolving threats such as viruses and malware infestation. There are also a number of new features and programs included. *The Advantages and Disadvantages of Using Mac OS Advantages: Security: Mac OS is a two-layered system: the attractive GUI sits atop a Unix core, and Unix is best-known for its security features. Its simply impossible to install a destructive trojan or virus unless the user explicity allows it root access via typing in the admin password. Mac OSs built-in firewall is set up to work unobtrusively out of the box as well as being highly configurable. Mac OS users should be vigilant about strange files and never allow an application they arent certain of admin access, but they dont need special anti-virus software. Reliability: Because OS X was designed from scratch from the ground up, Mac OS is incredibly stable. Apple controls production from start to finish, so every part of a Mac is designed and tested to work together. Ease of Use: Apples known for hiring the best industrial and interface designers around, and it shows in the intuitive nature of the GUI. I dont mean to sound like Im verging into fangirl territory here; its just true. Like the OSs reliability, the OSs functionality is designed to just work. The attractiveness of the interface cant be discounted. Some scoff that looks arent everything, but when youre spending 8 or more hours a day staring at a screen, its a relief to spend that time staring at a well-designed screen. Advanced users have easy command-line access with the Terminal app.. Mac OS Can Run Windows at the Same Time: Mac OS runs on Intel chips, which means you can run XP or Vista concurrently with Mac OS, with Boot Camp or Parallels software. Disadvantages: 1.os x only works on apple computers and not on other brands. 2.no games for os x as compared to windows. 3.all the best software and stuff comes for windows whereas with apple u have very little extra software and most programs will have to be from apple. 4.u cant customize os x exactly how u want it to be. 5.since u r os x on an apple computer then u r restricted to what they have to offer In my Opinion Microsoft windows is the best type which provides people with good features.

A critical reflection essay on Islam Essay

Islam being the fastest growing religion, has adhered a lot of positive as well as negative attention from the media. Due to this vast media influence stereotypes in Islam have increased from terrorism, Muslims have been discriminated merely due to the negative outlook that North America has portrayed upon them. The media tends to entwine the truth and to make Muslims seem perilous. Having that simple coherence of one another will be the start to making a difference. Islam is one of the most inspiring religions in the world. It is practiced in many countries, including Northern Africa, Saudi Arabia, Indonesia, Turkey, Iran, Pakistan and Iraq. Due to it being such a large religion, us people of the west tend to have a little understanding and knowledge about the religion. The very bitter truth is that not many people outside the religion can fully grasp their principles. With so many stereotypes being constantly circulated, it is very hard to get an evident picture about Islam both as a religion and as way of living. The first stereotype has to do with the jihad. Jihad literally means â€Å"The struggle in the path of God†, or â€Å"holy war†. This term unfortunately has been totally misunderstood and made to make it appear as though the Muslim people fight their way through all their problems. Jihad could mean ones spiritual struggle against infidels and does not always refer to actual violence. This pillar of faith has been completely turned around in order to portray Islam in a negative manner, which is surly something that we’ve adapted to through the media. Another stereotype is that women in the Muslim society are not treated equally or with respect. People feel this way because the women often wear a hijab which consists of a veil covering the head. This is actually a personal choice of the women, not a requirement. It was said in the Qu’ran that women and men were to be treated equally. By judging people too quickly we tend to forget to look inside rather then to make assumptions due to an appearance. Stereotypes such as the ones mentioned are absolutely biased and extremely unfair to the Muslim people. Many times, the media does not catch the side of the story where real people are being affected and influenced by what the society thinks and says about them. We seem to act as though we are more superior and that we are perfect and do not make mistakes. Just because some  people from a certain religion make a poor choice does not mean that everyone else is that religion is bound to as well. It is the same with the Muslim people. Just because there are terrorists who hurt themselves and those around them for selfish reasons, does not mean that every other Muslim is just as destructive. I feel that people need to be more open minded and try to do research and become more educated before judging and discriminating. If for once all religions saw eye to eye and did not try to put one another down then we would live in a much peaceful world. By not becoming educated, we basically take someone else’s opinion, or the medias and make it our own without looking deeper into the situation. If we just stop being selfish for just a moment, perhaps we can start again and try to live in harmony with our fellow human beings. During the past two weeks I have learned a lot about Islam, although I did know the basis of the religion people my family practices it. Although some of the thinks that I thought I knew turned out to be totally false I always thought the women never played a role in society and that the Muslim people really did have extremist views. After taking a closer look, I came to realize that I was not even close. It was so interesting and almost relieving to come to that realization that these people are simply misunderstood and are the victims of brutal discriminatory attacks. The biggest thing I learned from all this was not to judge a book by its cover. We can’t really have an opinion or pass judgment on a situation that we know nothing of. I realized now that people twist things in order to get a good story but as soon as people are educated about these matters, the media can no longer fool us into believing it all. Acting upon new knowledge, and most importantly correct knowledge is the way to see through the discrimination and look deep inside. Misconceptions and stereotypes about Islam and the Muslim community have increases majorly in the past couple of years. People have become too quick to judge and believe everything that the media tells them. Through knowledge and coherence about Islam and the Muslim people we would come to understand that it is all a simple misunderstanding and that really the Muslims are victims in this manifesto. We should not let others form opinions in our  head and to stay ignorant to the reality of the world. By doing this we save ourselves from becoming something that is not really human, but more so a robot that’s being controlled by the media, if we just stop and think for ourselves, we could live in harmony, and achieve world peace, a feeling that’s everlasting.

Essay on Causes of the American Revolution - 656 Words

On July 2, 1776, the second continental congress voted that the American Colonies were free from British influence. (Danzer,102) On July 4, two days later, they adopted the Declaration of Independence. These two events would begin what would become one of, if not the most important events in American History. It began the war of Independence, when America won its right to be free. There were many causes for the American Revolution. However most of them stemmed from paying for the French-Indian War.

The American Revolution began in a small Massachusetts town called Lexington. The governor of Massachusetts, Thomas Gage, learned that the Militia was stockpiling weapons, gunpowder, ammunition and other supplies. He ordered his troops to march on Lexington to confiscate the supplies. On April 19, 1765 a force of 700 British troops faced 70 minute men lined up on the green. The fighting was done in 15 minutes. 1 British soldier was injured and 8 minutemen were killed, 9 wounded. Gage did not find any supplies stockpiled however. On the march back, 3,000-4,000 colonials fired on the British, killing them by the dozens. Only reinforcements arriving from Boston stopped it from becoming a complete disaster. (Danzer, 98) According to The Americans, The popular gun during the early war was the brown Bess. Although highly inaccurate at distance, it reloaded quickly and was deadly at close range.
