Comparing Operating Systems Essay Example for Free

Comparing Operating Systems EssayOperating systems are the courses that create environment which enable the various(a) programmes to represent on a computer. That is why they are besides referred to as plat mixtures. The programmes that run on these platforms can range from simple office automation software products that enable us to do wordprocessing to games and also device drivers.All study companies make their software for multiple platforms. By platform we suppose the base environment that enables the communication amid the onboard devices bid the hard-disk, memory, various ports (input/yield) and the functions it will carry out using former(a) programmes that will run in that environment. For example if we look at Microsoft which makes the MS daub software that is consumptiond by most personal computers. They make MS Office for non only their own operating system namely Windows except also for macintosh and also for UNIX / LINUX.The function of the Operating s ystem is to provide an environment and background on which the other applications will run. This involves the use of Hardware like the display card, net take to the woods card, sound card, printers, scanners, other input and output devices.The hardware is linked to the computer through ports and communicates with the operating system through special software known as firmware (or drivers as it is commonly known).The most common Operating Systems are* Windows* mack* UNIX/LINUXWINDOWS This is true by Microsoft and has become a major platform for personal computers around the world. The name Windows was coined for the reason that one can open more than one application at the same time and work on each one independently simply by opening them in different windows. The earlier programmes did not have this capability and it revolutionised the industry. After this popularity, various versions were genuine with time and now-a-days, we see the launch of Windows Vista. Before this we had t he Windows XP, Windows 2000, Windows NT, Windows ME, Windows 98 etc.The popularity of Windows has been more so in its marketing strategy in that it has not curb itself to geographical boundaries. As a result of its becoming popular and being the most commonly used operating system also had advantages in monetary value of support. There were more people who had had experience of using Windows and some were able to even provide expertise and support where more advanced Microsoft support was not available e.g. in the remote areas of Africa and other rural areas.But like its popularity it had other people who liked to know more of the Operating system and who wanted to know more about how it works in the background. This led to a juvenile breed of programmers who liked to tear things apart and learn about the apparatus of the system. These people indeed found ways of overriding certain functions, disabling certain features and using the system to their own advantage and a term was coined for them to be known as Hackers. Windows has had to deal with this breed of programmers to continue to hold the market and continuously trying to prove that their Operating System is safe and secure. Some of these programmers after on turned to other ways of proving their skills by ontogenesis programmes that would install themselves on the system and wreak havoc on the user by destroying the data, playacting up with files and hijacking confidential information and sending it to them. These programmes are known as viruses, which like the clinical virus, avoid detection by changing form and then when the opportunity allows, do their bit of destruction.Windows uses the protocol TCP/IP to communicate with other computers. It is also the protocol that is used for communicating with the internet. mac This was developed by the makers of Apple Macintosh computers or Apple for short. It has upto now managed to hold a great deal of market share in the USA where it originated and in cidentally, Microsoft is also based there. The MAC operating system was developed solely for use in the Apple computers and it was programmed for specific hardware that was on the Apple PCs. Unlike Windows that was developed independent of the hardware, MAC on the other hand remained dependent on the hardware and the various versions that came were designed so as to beat the maximum output from the same hardware rather than for other new hardware.This was the reason that AppleMac as it was commonly called failed to capture the global market since people could not afford to spoil the hardware and also the level of support was lacking beyond the borders of USA. It did try to market the concept that you need to buy the hardware only once and then estimable keep upgrading the software but by this time it was too late. Far East especially Taiwan, Korea, Japan and China took on the opportunity and started developing motherboards for PCs for which Microsoft was willing to supply the nec essary Operating System.MAC has produced various versions so far and presently we are using MAC OS x10.5 also nicknamed Leopard just like its previous versions which were also named after the big cats. Except for the first one which was named Kodak after the Grizzly bear.Unlike Windows MAC does not have enemies of the likes of Hackers and computer virus creators. It does get them but since MAC is not a popular system of the likes of Windows the Hackers and Virus programmers find it not that worthwhile to work on them. However, it does not stiff that they are free from it, some people still do it and MAC also has to work around such people each time and new patches are constantly being developed.MAC uses the protocol AppleTalk to communicate with other computers. However, when it needs to go to the internet, it has to have TCP/IP protocol installed.UNIX/LINUX Unlike the Windows and MAC this is not only an Open Source Operating System but also Freeware. By Open Source we mean that th e main code of the programme on which it is based, is not secret or a property of anyone. Earlier when we talked about the Hackers getting into the operating system and disabling certain functions and enabling others to get it to work the way they want, this is exactly what an Open Source system allows one to do. One does not need to have a great deal of acquaintance of programming to be able to manipulate the programme and also one does not need to worry about breaking any law by doing so. The inventors of the programme have given a basic programme along with the freehand to do whatever with it and make it work to your specific requirements.By freeware, we mean that the inventors who have created this programme do not want any money for it and it is free for anyone to download and use. Other terms in this context are the Shareware, this kernel that the programmer will only give you the software to use on a trial basis for a express mail time so that you whitethorn evaluate it an d see if it suits your needs or not. If it does, then after the trial period you may buy the full version hence avoiding any spare cost that you could have incurred if it was not what you wanted.UNIX or LINUX which are both of similar nature though LINUX is the newer version, have another advantage in comparison to Windows and MAC in that, since these are Open source not many viruses or hackers try to disrupt it. However, UNIX is the main programme that hackers use to hack into either Windows or MAC since it allows you to work on the base level of the programme. UNIX also uses the TCP/IP protocol and thus one does not need to install other protocols to connect to the internet. Due to its popularity the LINUX has been taken by Sun Microsystems which is a major IT company based in Germany and they manufacture Sun computer systems. Sun computers use LINUX as their main operating system. When we run LINUX on a normal PC it is called referred to as a LINUXCOMPARISON AT A GLANCEWindowsM ACUNIX / LINUX* Popular around the world* Support is available even in remote areas* Uses the same protocol that is used to communicate with the internet.* Is very prone to hackers and viruses thus the creators have to constantly develop patches to overcome the threats.* Has more variety of programmes available as compared to other operating systems* Is only popular in the America* Has limited support around the world.* Is more secure than Windows in that it is not prone to hackers and viruses.* Uses the protocol AppleTalk to communicate with other Apple computers but needs the TCP/IP to communicate with the internet.* It is freeware so anyone can use it free of cost.* It is an open source system allowing one to customise it to ones own needs and requirements without fear of any licit liability.* It uses the TCP/IP protocol to communicate thus is compliant with the internet.* Most internet servers still use UNIX as their main operating system
