The following tables compare '''general and technical information''' for a number of '''[[operating system]]s'''. Please see the individual products' articles for further information. The table only includes systems that are widely used and currently available. Due to the large number and variety of available [[Linux distribution]]s, all of these operating systems are grouped under a single entry in these tables. See [[comparison of Linux distributions]] for a detailed comparison. There are also a wide variety of minor BSD operating sytems, many of which can be found at [[Comparison of BSD operating systems]].

|colspan=2 align=center|Here are some open '''[[Wikipedia:WikiProject Irish Republicanism|WikiProject Irish Republicanism]]''' tasks:

The tables specifically do not include subjective viewpoints on the merits of each operating system. For this kind of information, please see [[operating system advocacy]].

<!-- NOTES TO EDITORS, PLEASE READ THIS ====================================================================

- All tables in this article are meant to be sorted alphabetically

- All tables should list the same operating systems. If you add an OS, please add it to ALL tables.

- The unfixed bug count in the security table is updated automatically by User:SecuniBot. There is no

need to update that column manually, except to add the link to the secunia.com page corresponding to

an OS the first time. See below.

- Please have a look at the conventions used in existing table entries when adding new data. E.g.

the "Target system type" column should list systems types like "Server", "Workstation", "Home Desktop",

"Network Appliance".

- It's not necessary to list all architectures in the "supported architectures" columns. Just list the primary

ones (maybe up to five) and add "some others" or "N others" or something like that if there are more.

Specifically, its not necessary to add an arch to this list just because an experimental port exists.

Listed archs should be fully supported.

- The same goes for filesystems, just list the important ones.

- Use "?" or the {inc} template for missing data, not "-". "-" is used to mean "none" / "n/a" in these tables.

- Some systems that have been removed from this comparison by consensus on the talk page. Please refer

to the discussion there before re-adding them: AmigaOS, BeOS, Reactos

======================================================================================================== -->

<!-- SECUNIBOT PERMITTED ===================================================================================

This comment gives the bot [[User:SecuniBot]] permission to update the ''unpatched vulnerabilities''

column of the Security table. For the bot to update an entry, it must have the format

| [http:/secunia.com/product/<number>/<number>] || <date>

Where <number> is any sequence of digits, and <date> is either '-' or a date in numeric format, i.e.

[[<number>-<number>-<number>]]

All other entries will be ignored. The bot fetches the linked secunia.com page and counts the advisories

marked ''less critical'' or above. The footnote below the table that gives the ''last updated'' date is

also adjusted. The bot is run by [[User:Sperling]]. The source is available at [[User:SecuniBot/source]].

{{fnb|6}} Operating systems where the GUI is not installed and turned on by default are often bundled with an implementation of the [[X Window System]]. However, installing X is usually optional.<br />

{{fnb|7}} Most operating systems use proprietary APIs in addition to any supported standards.<br />

{{fnb|8}} Unlike NetBSD and FreeBSD, OpenBSD includes the [[X Window System]] as base install sets rather than packages within the [[ports collection]]. It includes some local changes and is managed as part of the OpenBSD source tree.<br />

{{fnb|10}} Posix [[Access Control Lists|ACL]] support is included in Linux 2.6, but requires a file system capable of storing them (such as [[ext3]], [[XFS]] or [[ReiserFS]]).<br />
