Unix-like, real-time, embedded operating system

QNX is an Unix-like, real-time operating system that is embedded in cars, medical devices, machinery, and other devices. The QNX operating system contains a microkernel that handles basic core tasks and a group of servers / daemons outside of the kernel that handle most other tasks. This design gives end-users and developers greater control (i.e. freedom) over the operating system.[1] BlackBerry (formerly RIM) devices such as the BlackBerry PlayBook tablet and the BlackBerry smartphone use modified versions of the QNX operating system.
