State whether the following statements are True or False for the features of real time operating system. i) fast process or thread switch ii) ability to respond to external interrupts quickly. iii) minimization of intervals during which interrupts are enabled. iv) preemptive scheduling based on priority

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. RTOS processing time requirements are measured in milliseconds. Any delays in responding could have disastrous consequences. Real-time operating systems have similar functions as general-purpose OSes (GPOSes), like Linux, Microsoft Windows or macOS, but are designed so that a scheduler in the OS can meet specific deadlines for different tasks.

Real-time operating systems have similar functions as general-purpose OSes (GPOSes), like Linux, Microsoft Windows or macOS, but are designed so that a scheduler in the OS can meet specific deadlines for different tasks.

RTOSes also commonly appear in embedded systems, which are a combination of hardware and software designed for a specific function and may also operate within a larger system

Examples of the real-time operating systems: Airline traffic control systems, Command Control Systems, Airlines reservation system, Heart Pacemaker, Network Multimedia Systems, Robot etc. Hard Real-Time operating system: These operating systems guarantee that critical tasks be completed within a range of time.
