It would be appreciated if users make additional contributions to this section.
If you use an application which is not included here, create a new page and write something about it.
If you have additional information about one which is here, add it.

An Appliance is a special kind of application. Typical examples are webservers, fileservers, etc.
Machines running appliances are very rarely turned off, if at all.
If there is any user interaction with an appliance, it is usually from a different machine than the one running the appliance.
Please add information about Appliances on a different page.
