FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A real-time operating system (RTOS) is an OS that guarantees real-time applications a certain capability within a specified deadline. RTOSes are designed for critical systems and for devices like microcontrollers that are timing-specific.

Detailed explanation-2: -Real-time operating systems (RTOS) are used in environments where a large number of events, mostly external to the computer system, must be accepted and processed in a short time or within certain deadlines.

Detailed explanation-3: -In this type of system, processing must occur within specified constraints. Otherwise, the system will fail. A real-time operating system (RTOS) is an operating system that executes tasks with strict time deadlines.

Detailed explanation-4: -Conventional process control systems today are organized around a single computer with a realtime operating system as the key element. The function of the realtime operation system is to control resources in the system shared by application tasks including input/output devices, computer memory, and the CPU itself.

Detailed explanation-5: -Real-time task scheduling essentially refers to determining how the various tasks are the pick for execution by the operating system. Every operating system relies on one or more task schedulers to prepare the schedule of execution of various tasks needed to run.
