What is an operating system and why is it important?
An operating system is the most important software that runs on a computer. It manages the computer’s memory and processes, as well as all of its software and hardware. It also allows you to communicate with the computer without knowing how to speak the computer’s language.
What is RTOS kernel?
The kernel is part of the operating system that offers core services to application software that runs on a processor. The kernel offers an abstraction layer that hides processor hardware details from the application software that it uses to run….
Is Android an RTOS?

Is Linux a RTOS?
… making Linux just a little more fun! A real-time operating system (RTOS)  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.
What are the objectives of OS?
What are the objectives of the operating system?

What is RTOS microcontroller?
An RTOS is an operating system designed to manage hardware resources of an embedded system; it creates multiple threads of software execution and a scheduler for managing these threads. Another way to put it is a scheduling kernel that creates a multi-tasking and deterministic run-time environment….
What is difference between OS and RTOS?
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….
