QNX is a real-time operating system designed for embedded systems, which are specialized computing devices that perform dedicated functions. It is known for its reliability, performance, and ability to manage multiple tasks simultaneously. Originally developed in the 1980s, QNX is widely used in various industries, including automotive, medical devices, and telecommunications. One of the key features of QNX is its microkernel architecture, which allows for a minimal core system while enabling additional services to run as separate processes. This design enhances system stability and security, making it a popular choice for applications that require high availability and quick response times, such as in automotive systems and industrial automation.
