This document provides an overview of 10 different operating systems: Windows, Linux, Mac OSX, UNIX, BSD OS (OpenBSD), Sun Solaris, AIX, Linux, IRIX/HPUX/others, and DOS. It describes the origins and key features of each OS, such as Windows being introduced by Microsoft in 1985 and becoming the most widely used OS, Linux being an open source alternative to Windows, and UNIX spawning various variants including Linux and BSD.

1. 1. Microsoft Windows
OS made by Microsoft Corp.. It has an easy to understand user interface and extensive software
support. Many hardware manufacturers suggest using this OS. This OS has the disadvantage that its
VIRUS billions of its kind. As well as price. An OS with the most users in the world today.
Windows operating system was first introduced in 1985. Semulanya windows operating system was
introduced with the name of Interface Manager. Use of this operating system was initially not very
interesting. It happens to be introduced windows operating system version 3.0 in May 1990.
2. GNU Linux
The operating system is based on Open Source (Non-Owned). Operating System was introduced by
Linus Torvalds and growing so fast that almost exceeds the number of Windows users in the world.
Desktop has many types such as KDE, Gnome, XFCE and so on. Also many species such as Ubuntu,
Mandriva, DEBIAN, GOOGLE OS etc..
3. MAC OSX
If you're looking for a stable operating system with a friendly interface and powerful, Mac OS X could
be one option. Although FreeBSD has had a desktop interface for computer professionals, but less
suitable for keliatannya paraniod, grandfathers, and grandmothers. Mac OS X is more suitable for
them because it has a very intuitive design. They can directly use it without much thought. Mac OS
includes many things that are not necessary to run an internet server, and can only run on Apple
hardware. Thus, for kerperluan inexpensive and powerful servers, Mac OS is not recommended.
Although, you can not see the source code Mac OS GUI interface, you can still see the BSD source
code in it. Apple had me releasenya codename Darwin.
4. UNIX
UNIX is an operating system created by Ken Thompson and Dennis Ritchie, developed by AT & T Bell
Labs. UNIX is designed as a portable Operating System, Multi-Tasking and Multi-User. UNIX
Operating System more emphasis on Workstation and Server, Because of the high availability and
compatibility causes UNIX can be used, copied and modified so that UNIX was developed by many
people and caused a lot of variants of UNIX.
UNIX itself is written in C language that is similar to the DOS UNIX is Line / Text Command Based
otherwise it was a UNIX Operating System secure than other operating system, because every file,
directory, user and group has its own set of permissions to access. Because of the support for the
GNU Project, we then developed into LINUX UNIX (One variant of UNIX).
5. BSD OS (OPEN BSD)
OpenBSD is a fork of NetBSD since 1996, the main goal is to make the safest OS BSD. OpenBSD is a
BSD of the first to support hardware-accelerated cryptography (allow to download encrypt and

2. decrypt information in a short time), the developer is very proud of the fact, the default installation
of OpenBSD can not be hacked for 4 years!
The OpenBSD mania has Meng-audit all OpenBSD code, fixing security holes that may diexploitasi.
However, in terms of user-friendly, unlike FreeBSD OpenBSD.
6. Sun Solaris
Solaris is one of the most well known UNIX world. Solaris created by Sun Microsystems. Solaris
berjalah on high-end hardware that can support tens of processors, GB RAM, and hard drive. He was
mostly used as a platform by enterprise applications, such as Oracle. Solaris is designed to run on
SPARC processor manufactured by SUN. Because SUN controls its own hardware and software, they
can develop a system to fitur2 interesting, like, hot-swappable RAM, motherboard, hard drive, CPU.
7. AIX
One is IBM AIX UNIX pasaing. AIX journaling filesystem claims to have the best, able to record the
entire disk transaction happened, so was able to recover the system without much of a problem this
capability increases reliability. AIX also based on BSD.
8. Linux
Linux is a UNIX clone, written completely from under more than a decade ago. Linux with BSD in
many ways, but BSD has had a culture that has long, and be kinder to the commercial world. It
requires the commercial users to provide feedback back to linux, while BSD does not have such
restrictions. Among users of UNIX, there is a perceived conflict between BSD and Linux camps. But if
you dig deeper, otherwise, you'll see how developers communicate and cooperate with the friendly
and open-minded. Only a small percentage of users and developers that create friction.
9. IRIX, HPUX, and others
Another UNIX IRIX (Silicon Graphics), a well-known UNIX graphics application, as well as HP-UX
(Hewlett-Packard), which is popular among a large enterprise. Many high-end software packages
such as Informix, specially designed applications on HP-UX platform. You will also meet other
competitors such as SCO and UnixWare. They also UNIX, but not as popular as others. There's more
UNIX such as: A / UX (Apple), Sinix (Siemens UNIX) and Xenix (Microsoft). Yes, Microsoft is the
vendor UNIX years ago. Then sold to SCO Xenix into SCO UNIX and.
10. DOS
DOS Operating System is one of the software included in the operating system group. Disk Operating
System used on disk storage media, either floppy or hard disk. Before the era of Windows, MS-DOS,
short for Microsoft Disk Operating System, is an operating system that is widely used by the IBM-PC
or compatible with it. Microsoft makes MS-DOS as a mainstream operating system, before
eventually stop supporting MS-DOS are slowly when they make a graphical interface-based

3. operating system (also known as GUI) for the mainstream market, which is referred to as Microsoft
Windows.
Initially in 1980, the team made the operating system Petterson for Seattle Computer Products
requiring S-100 system by using the INTEL 8086. Operating System is called QDOS (Quick and Dirty
Operating System). At the end of 1980, QDOS was developed and named 86-DOS (DOS 8086). To
date there have been several DOS was launched, such as DOS 1.0, DOS 2.0, DOS 3.0, DOS 3.1, etc..
