How many types of general-purpose operating systems are there?
The primary computer operating systems in use are Windows Server, Windows XP, 7, 8 and 10, macOS, the many versions of Linux and Unix, IBM i (from the midrange AS/400) and z/OS (IBM mainframes). DOS is still used for some applications, and there are several more (see real-time system and embedded system).
What is difference between RTOS and GPOS?
In a GPOS, task scheduling is not always based on which application or process has priority. They typically use a “fairness” policy to dispatch threads and processes. An RTOS, on the other hand, always utilizes priority-based scheduling. … In a GPOS, a high-priority thread cannot preempt a kernel call.
How is RTO different from OS?
An RTOS can effectively handle interrupts based on priority to control scheduling. Unlike a general-purpose OS, an RTOS is expected to meet computational deadlines, regardless of how bad the scenario can get for the RTOS. … Additionally, one of the primary provisions of an RTOS is that interrupt latency is predictable.

Is Linux a RTOS?
… making Linux just a little more fun! A real-time operating system (RTOS) [1] is an operating system capable of guaranteeing timing requirements of the processes under its control. While a time-sharing OS like UNIX strives to provide good average performance, for a RTOS, correct timing is the key feature.
