Definition - What does QNX mean?
Techopedia explains QNX
QNX was rewritten for the POSIX model in the late 1980s to be more compatible at a lower level, and became QNX 4. In the late 1990s, a new version of QNX was designed from the ground up to be SMP capable and support all current and any new POSIX APIs while retaining the microkernel architecture. The company was acquired by RIM in April of 2010. The BlackBerry Tablet OS that first came out for the BlackBerry Playbook announced in 2010 was based on QNX and was later built up to become the BlackBerry 10 OS released in 2011.
QNX remains the OS of choice for automobile manufacturers for their in-car infotainment systems and is also featured in Apple's iOS-centric car infotainment system CarPlay, which allows users to seamlessly integrate their iPhones and iPads to the car's system to allow for voice recognition control through Siri.
