Scheduling Algorithms and Starvation:

Scheduling algorithms are used by the operating system to manage the allocation of resources to processes. There are several scheduling algorithms, and each has its advantages and disadvantages. However, some scheduling algorithms can cause starvation.

Definition of Starvation:

Starvation is a situation where a process is denied resources that it needs to complete its execution. In other words, a process is waiting for a resource that is held by another process, and it cannot proceed until that resource becomes available.

Scheduling Algorithms that may cause Starvation:

1. Round Robin:
Round Robin is a scheduling algorithm that allocates a fixed time slice to each process in a cyclic order. If a process requires more time than the allocated time slice, it is preempted and moved to the end of the queue. However, if a process with a higher priority is continually added to the queue, it may cause lower priority processes to starve.

2. Priority:
Priority scheduling is a scheduling algorithm that assigns priorities to processes based on their importance. Processes with higher priorities are executed first. However, if processes with lower priorities are continually added to the queue, they may never get the chance to execute, causing starvation.

3. Shortest Remaining Time First:
Shortest Remaining Time First is a scheduling algorithm that prioritizes processes based on their remaining burst time. Processes with the shortest remaining burst time are executed first. However, if a process with a very long burst time is continually added to the queue, it may cause other processes to starve.

Conclusion:

In conclusion, Round Robin, Priority, and Shortest Remaining Time First are the scheduling algorithms that may cause starvation. These algorithms prioritize certain processes over others, and if the queue is continually filled with high-priority processes, lower-priority processes may never get the chance to execute and may be starved of resources.
