Question

Discuss the main benefits of deploying QNX Operating Systems for applications.

Answer 1

Answer:

QNX Operating Systems:

QNX is a commercial Unix-like real-time operating system, aimed primarily at the embedded systems market, developed by QNX Software Systems from Canada.QNX is a multi-purpose operating system, that can work not only as an embedded system but also as a server or desktop operating system.

Main benefits of deploying QNX Operating Systems for applications:

1. Built-in Mission Critical Reliability: Time-tested and field-proven, the QNX Neutrino RTOS is built on a true microkernel architecture. Under this system, every driver, application, protocol stack, and filesystem runs outside the kernel in the safety of memory-protected user space.

2. Advanced Security Mechanisms: QNX Neutrino provides a comprehensive system approach to security, designed to help you easily build impenetrable systems. Security is achieved by layering different optional security mechanisms including secure boot, integrity measurement, sandboxing, access controls (mandatory or discretionary) and rootlessexecution. The solution also provides the ability to audit and attest to the integrity of the system.

3. Realtime Support: An RTOS can help make complex applications both predictable and reliable; in fact, the precise control over timing made possible by an RTOS adds a form of reliability that cannot be achieved with a general purpose operating system. QNX Neutrino RTOS makes computing problems easier to solve, particularly when multiple activities compete for a system’s resources.

4. Capability to Port Linux Source Code: Developers can ramp up quickly because QNX Neutrino looks and feels like Unix and provides a familiar open standards- based development environment. Develop using C/C++, HTML5, Qt, Python, etc. Port legacy and open-source UNIX, Linux, and other source code over easily as QNX Neutrino is certified POSIX compliant.
