Description: Reactive scheduling is an approach to process management in computing systems that prioritizes task execution based on immediate need. Unlike other scheduling methods that may rely on criteria such as arrival time or estimated execution time, reactive scheduling focuses on responding to real-time events. This means that processes requiring urgent attention are addressed immediately, allowing for greater efficiency in situations where latency is critical. This type of scheduling is especially relevant in systems where user interaction or response to external events is paramount, such as in embedded systems or real-time applications. Key characteristics of reactive scheduling include adaptability to changes in the execution environment and the ability to dynamically prioritize tasks, making it a valuable option in environments where conditions can change rapidly. In summary, reactive scheduling is an approach that seeks to optimize system response to immediate demands, ensuring that the most critical processes are attended to without delay.
