Summarizing a Little Bit Operating Systems

Since the early years in computing, Operating Systems were used in computers to make an interface between the human user and the computer machine. OS or Operating System can be defined by “operating system is the software that controls the overall operation of a computer” (Glenn Brookshear, J, 2011).

Nowadays, users have plenty of options to choose as its operating systems, there are Operating Systems for final users, small business, medium and large business, mobile, server/networks, and so many others.

Operating Systems have some characteristics to be compared, in this paper will be covered: Usage (Desktop, Server?), Ease of Use (Graphical, Non-Graphical) and Costs.

            The most popular operating systems for desktop final-users nowadays are:

  • Microsoft Windows;
  • Apple Mac OS;
  • Linux.

For mobile most users use:

  • Apple iOS;
  • Google Android;
  • Windows Mobile.

And Server/Network Computers:

  • Linux;
  • FreeBSD/OpenBSD/NetBSD;
  • Oracle Solaris;
  • Windows Server;

To have a better understanding of OSs it is necessary to know a little bit about history. Most of them are based on the Unix Operating System, which is: Apple Mac OS, Oracle Solaris and Linux (including Google Android and Apple iOS). The UNIX Operating System was created in 1969 by system engineers at AT&T’s Bell Labs (Unix Help, 2014), and since nowadays it continues to be very influencing for the modern Operating Systems. Linux, in the beginning, was more focused in the server business, with a small slice of the market for final-users, but nowadays it became more popular with the effort of open-source collaborators and investing companies. Microsoft Windows, which is the most popular OS worldwide, was completely developed by Microsoft Corporation, not following the Unix OS concepts.

The ease of use is a very important topic to be pointed. Microsoft Windows became the most popular OS in the world because it has been always oriented by the GUI system, nevertheless, Mac OS is as simple as Windows, but it wasn’t much popular because of the Apple’s business strategy to sell their own built computers.

The table bellows points, the big difference between prices for Operating Systems.

Operating System Price
Windows 8.1 (Amazon, 2014) $95.91
Mac OS X version 10.6.3 Snow Leopard (Amazon, 2014) $29.38
Ubuntu Linux (Amazon, 2014) $10.99 (free to download)

While Apple OSX is cheaper than Microsoft Windows, you must consider that Apple sells its machines, and you can use only with Apple computers, on the other hand, Microsoft only sells operating systems but It can be used in any PC based computer. Ubuntu is totally free for download, but if you want to have the original DVD you can buy for a very cheap price at Amazon.

I personally used almost all the covered Operating Systems in this paper. I became a Linux enthusiast in 1999, using Caldera Open Linux and afterward used Slackware, Debian, Mandrake, Conectiva, RedHat, and others; I tested also NetBSD and OpenBSD OSs; I used Microsoft Windows since the Windows-95 version (going through Windows-98, Windows ME, Windows 2000, Windows XP, Windows Vista and Windows 7) and since 2012 I am a Mac OS user. My cell phone is an Android 4 operating system, which I really like to use.
