    How VxWorks handles process scheduling and memory management in comparison to QNX

    QNX is a microkernel real-time operating system, from now on referred to as an RTOS. A microkernel RTOS is special in the way that the OS is built up with a number of small services which each handle a specific task, this is basically a set of system calls which is available to the developer. These services only implement low-level communication over network and between processes, process scheduling and interrupt handling. Other OS functions as file-system and device drivers are deployed as user processes outside the kernel. In contrast most other OS use a monolithic kernel. In that case all kernel functions reside in…

    Unix

    However, in the 1990s there are competitors in the market, namely, Microsoft Corporation with its Windows NT product. But UNIX-based software suppliers are not just turning over and letting the competitors win. UNIX remains, and will remain a major player in the marketplace. The unique advantage of the UNIX operating system when it was introduced was that it could (and still does) run on dissimilar machines, unheard of prior to 1969. UNIX also can run more than one program at a time, store complex graphics and databases, and link to other UNIX and mainframe computer systems, including DOS since the late 1980s. UNIX-based systems control various programs written by many companies to distribute information between multiple computers within the network. This minimizes user costs and eliminates system-wide hardware crashes.…
