ExTen OS

ExTen Distributed Operating System, or ExTenD OS, is a computer operating system designed by the Descendants, resembling GUI-based operating systems from Mac OS System 6 through to Windows 10. The code is mostly based on Linux, but ExTenD OS supports applications from all Mac OS versions and executables from all Windows versions.

As the full name suggests, ExTen is a Distributed OS, meaning that it is run from a server rack attached to the user's username. The server rack is part of the Library of Virtually Everything and is library property, but the data stored on the server rack is wholly owned by the user. Each server rack provides a finite amount of storage and RAM, which is gradually expanded as technological development provides better components. CPU and GPU performance is determined by the subscription tier of the username, ranging from a free tier with basic specs to a top tier meant for use by hardcore gamers, scientists and graphics artists. Each tier is gradually improved as better technology becomes available, often with one tier receiving "hand-me-down" specs from the next tier up.

The qTop was the first well-known computer to make use of the ExTenD system.
