What are the key developments in thread scheduling algorithms?

Thread scheduling algorithms have evolved significantly over the years, starting from simple FIFO methods to more complex algorithms like Round Robin, Priority Scheduling, and Multilevel Queue Scheduling. Each development aimed to improve efficiency and responsiveness in multitasking environments.

Can you explain how Round Robin scheduling works?

Round Robin scheduling allocates a fixed time slice to each process in a cyclic order. When a process's time slice expires, it is moved to the back of the queue, allowing other processes to execute. This method is fair and prevents any single process from monopolizing the CPU.

What are the advantages of using Priority Scheduling?

Priority Scheduling allows more important tasks to be executed first, improving overall system responsiveness. However, it can lead to starvation for lower-priority processes if not managed properly.

How did these algorithms impact modern operating systems?

These algorithms are foundational in modern operating systems, enabling efficient resource management and multitasking capabilities, which are crucial for user experience and system performance.
