                                       REAL-TIME SCHEDULING   RTS stands for "Real-Time Scheduling." RTS is a scheduling technique used to manage tasks and processes in real-time systems. Realtime systems have strict timing requirements, where tasks must be completed within specific deadlines to ensure correct system operation. In particular, these tasks are related to control of certain events (or) reacting to them. Real-time tasks can be classified as hard real-time tasks and soft real-time tasks.  There are two main types of real-time scheduling:             1. Hard Real-Time Scheduling: In hard real-time systems, missing a deadline can lead to catastrophic consequences. Tasks have absolute deadlines that must be met under all circumstances. Meeting deadlines is the highest priority, even if it means sacrificing other tasks or pro...

Advanced Operating Systems (OS) refer to a category of operating systems that offer more sophisticated features and capabilities compared to traditional or basic operating systems. These advanced features are designed to meet the specific demands of modern computing environments, including distributed systems, real-time systems, and high-performance computing. Some of the common types of advanced operating systems include:  Real-Time Operating Systems (RTOS): RTOS is designed to handle real-time applications where timely response is critical. They are used in embedded systems, control systems, robotics, and other time-sensitive applications. RTOS ensures that tasks are executed within specific time constraints, minimizing delays and providing predictable and deterministic behavior.            A distinct feature of real-time systems is that jobs have completion deadlines. A job should be completed before its deadline to be of use (in soft real-ti...
