QNX

Updated: 04/26/2017 by Computer Hope

QNX logoQNX is a real-time operating system for embedded systems. It was first released for the 8088 processor in 1982 by the Canadian software company Quantum Software Systems.

Note: In 2009, QNX was purchased by BlackBerry for use as the foundation for their BlackBerry Tablet OS and BlackBerry 10 operating systems.

How does it work?

QNX is a microkernel OS that breaks down the various components of the operating system into small programs called "servers." Each server can be disabled by system designers for their custom needs, which allows QNX to be a very lean and efficient OS. It uses very little disk space, even fitting onto a single floppy disk as recently as the late 1990s.
