Operating Systems

Most personal computers are equipped with a version of the Windows operating system, whereas Apple personal computers have a different operating system. Other choices are also available, such as UNIX, FreeBSD and Linux. Why do you think Windows is so prevalent? What do the other systems have to offer that Windows does not? Who uses the other systems?

Why do you think Windows is so prevalent?

I think that the Windows OS is so prevalent because of the graphical user interface that is so easy to use and it can be installed in most of the PCs available on the market. The Mac OS works only on Macintosh computers and this is a big disadvantage. The UNIX is not for the faint of heart because of its command-line interface, cryptic Instructions, and the fact that it requires many commands to do even simple tasks. Linux can run on nearly any computer and can support almost any type of application but uses a command-line interface with the availability of some windows-based GUI environments, called shells. According to the FreeBSD website the FreeBSD OS is designed for specific processors such as Intel x86 and Itanium, AMD64, Alpha, Sun UltraSPARC.

What do the other systems have to offer that Windows does not?

Unix is more flexible and can be installed on many different types of machines, including main-frame computers, supercomputers and micro-computers. It is more stable and does not go down as often as Windows does, therefore requires less administration and maintenance. It has greater built-in security and permissions features than Windows. It possesses much greater processing power than Windows. It is the leader in serving the Web. About 90% of the Internet relies on Unix operating systems running Apache, the world's most widely used Web server. The software upgrades from Microsoft often require the user to purchase new or more hardware or prerequisite software. That is not the case with Unix.   http://linux.about.com/cs/unix101/a/whyunix.htm
