Commercial, free, open source and operating systems developed at universities as well as their derivatives are included. It does not take place a distinction after the level of development, application purpose, distribution or hardware platform. Operating systems with only different version numbers are considered only if they are technically clearly different to each other.

This list offers hundreds of operating system product and project names, many of them are based on the same operating system more or less with more or less differences in the source code. The most operating systems can be traced to few development lines and derive from a small amount of system software. This applies especially to Linux distributions with a low number of main distributions. Further projects which largely use the same code base have forged to new distributions. Depending of this there forged smaller projects with differences in the composition of the applications or source code. Other operating system families are Windows and Unix.

The OSDP provides the following information for interested visitors. Subdivided into the 4 main topics Basics, Operating Systems, Developers and Project related shall make the search for the desired information easier.

You find much relevant and compressed information about operating systems and its developer on this independent web site for the archiving of informations.

Many screenshots and version information complete the articles with an objective description. The historical time classification of operating systems is checked as far as possibly and several information sources were included.

GUI - Short for Graphical User Interface, a GUI Operating System contains graphics and icons and is commonly navigated by using a computer mouse. See the GUI definition for a complete definition. Below are some examples of GUI Operating Systems.

Multi-user - A multi-user operating system allows for multiple users to use the same computer at the same time and different times. See the multi-user definition for a complete definition for a complete definition. Below are some examples of multi-user operating systems.

Multithreading - Operating systems that allow different parts of a software program to run concurrently.
