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.
