These tables compare general and technical information for a number of widely used and currently available operating systems.

Note: Because of the large number and variety of available Linux distributions, they are all grouped under a single entry; see comparison of Linux distributions for a detailed comparison. There are also a variety of BSD operating systems, covered in comparison of BSD operating systems.

  1. 1.0 1.1 Most OS distributions include bundled software with various other licenses.
  2. GNU is a recursive acronym for GNU's Not Unix, which was chosen because its design is Unix-like, but differs from Unix by being Free software and by not containing any Unix code.
  3. Minix inspired the Linux kernel. No code from Minix was used to create the Linux kernel.
  4. Although Lisa OS ran on the same (albeit a slower version) microprocessor and was developed by Apple Computer at the same time as Mac OS, they were developed as different projects, sharing only a similar GUI between them. http://folklore.org/StoryView.py?story=Hungarian.txt
  5. Mac OS 7.6 was the first Mac OS operating system to be labeled Mac OS. Operating systems prior to this were named System Software 0.1 (available only to developers) through System Software 7.5, and known as System #.# for short.
  6. Mac OS versions up to 7.5.5 are available free of charge at http://www.info.apple.com/support/oldersoftwarelist.html
  7. PC-BSD uses FreeBSD as a base system with custom configuration and several desktop oriented tools to create an easy to use FreeBSD system for Desktops and Workstations.
  8. 8.0 8.1 Windows Vista was released to manufacturing on November 8, 2006, and was subsequently made available to software developers and businesses in November 2006, with retail availability following on January 30, 2007

Name Computer architectures supported File systems supported Kernel type Source lines of code GUI default is on[t 1] Package management Update management Native APIs[t 2] Non-native APIs supported through subsystems
  1. 1.0 1.1 Operating systems where the GUI is not installed and turned on by default are often bundled with an implementation of the X Window System, installation of which is usually optional.
  2. 2.0 2.1 Most operating systems use proprietary APIs in addition to any supported standards.
  3. 3.0 3.1 Amiga OS features since OS 2.0 version a standard centralized Install utility called Installer, which could be used by any software house to install programs. It works as a LISP language interpreter, and install procedures could be listed as simple text. AmigaOS can also benefit of a 3rd party copyrighted library called XAD that is available for all POSIX (Unix, Linux, BSD, and for AmigaOS, MorphOS, etc.). This library is freely distributable and publicly available on Aminet Amiga centralized repository of all Open Source or Free programs and utilities. XAD.Library, complete with GUI Voodoo-X, is based on modules and capable to manage over 300 compression methods and package systems (Voodoo-X GUI supports 80 package systems), including those widely accepted as standards such as .ZIP, .CAB, .LHA, .LZX, .RPM, etc.
  4. 4.0 4.1 A standard AmigaOS installation requires usually only few files (typically 3 to 10 files) to be copied in their appropriate directory, and libraries and language files for national localization to be put in their standard OS directories. Any Amiga user with some minimal experience knows where these files should be copied and could perform programs installations by hand.
  5. AmiUpdate is capable to update AmigaOS files and also all Amiga programs which are registered to use the same update program that is standard for Amiga. Updating AmigaOS requires only few libraries to be put in standard OS location (for example all libraries are stored in "Libs:" standard virtual device and absolute path finder for "Libs" directory, Fonts are all in "Fonts:" absolute locator, the files for language localization are all stored in "Locale:" and so on). This leaves Amiga users with a minimal knowledge of the system almost free to perform by hand the update of the system files.
  6. 6.0 6.1 NetBSD and OpenBSD include the X Window System as base install sets, managed in their respective main source repository, including local modifications. Packages are also provided for more up-to-date versions which may be less tested.
  7. only i686 CPU
  8. 8.0 8.1 Windows can read and write with Ext2 and Ext3 file systems only when a driver from FS-driver or ext2fsd is installed. However, using Explore2fs, Windows can read from, but not write to, Ext2 and Ext3 file systems. Windows can also access ReiserFS through rfstool and related programs.

Known unpatched vulnerabilities (severity is accounted for)[s 1]
  1. 1.0 1.1 Comparison of known unpatched vulnerabilities based on Secunia & SecurityFocus reports with severity of Not critical & above. Update lists manually with oldest published date(s).
  2. AIX use the PowerPC architecture which offer page-level protection mechanism. Since AIX version 5300-03 (5.3), this feature can be activated using the sedmgr command.
  3. The GCC stack protection (a.k.a. ProPolice Stack-Smashing Protector) has been enabled in base system since FreeBSD 8.0-RELEASE.
  4. POSIX ACL support is included in Linux 2.6, but requires a file system capable of storing them (such as ext3, XFS or ReiserFS).
  5. A jail mechanism is available separately in the Linux-VServer project, but is not integrated into any mainline Linux kernel.
  6. ACLs were added to Mac OS X beginning with version 10.4.
  7. ACLs are available only in OS/2 Server versions with HPFS386 filesystem.
  8. Additionally swap space may be encrypted during installation, uses memory based tmp file storage by default.
  9. 9.0 9.1 "Solaris Containers" (including "Zones") are a jail-type mechanism introduced with Solaris 10.
  10. 10.0 10.1 Through ZFS
  11. 11.0 11.1 11.2 Available on XP sp2, 2003 sp1 and newer.
  12. 12.0 12.1 12.2 By default, software-enforced DEP helps protect only limited system binaries.
  13. Zeta has full Unix file permissions, but the OS is single user, and users always run as superuser.
  14. STOP 6 is certified under Common Criteria at EAL5+.
