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 won’t 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. It’s simply impossible to install a destructive trojan or virus unless the user explicity allows it root access via typing in the admin password. Mac OS’s 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 aren’t certain of admin access, but they don’t 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:
Apple’s known for hiring the best industrial and interface designers around, and it shows in the intuitive nature of the GUI. I don’t mean to sound like I’m verging into fangirl territory here; it’s just true. Like the OS’s reliability, the OS’s functionality is designed to just work.
The attractiveness of the interface can’t be discounted. Some scoff that looks aren’t everything, but when you’re spending 8 or more hours a day staring at a screen, it’s 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 can’t 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
