Description: Absolute priority is a process scheduling policy in operating systems where processes are executed solely based on their priority level, without considering other factors such as arrival time or execution time. In this model, each process is assigned a numerical priority, and the operating system always selects the process with the highest priority for execution. This strategy can be effective in situations where it is crucial to ensure that certain critical processes complete before less important ones. However, it can lead to issues such as starvation of low-priority processes, as these may be constantly overshadowed by higher-priority processes. Absolute priority is particularly relevant in real-time systems, where meeting deadlines is essential. Despite its advantages, its implementation requires careful management to avoid situations where important processes are left unattended for extended periods. In summary, absolute priority is a straightforward and efficient approach to process scheduling, but it must be used cautiously to maintain a balance in the execution of all system processes.
