Starvation refers to a situation in which a process is ready to execute but is continuously denied access to a processor in deference to other processes.
Explanation:
- Starvation occurs when a process is unable to proceed or make progress due to being continually bypassed or overlooked in favor of other processes.
- It often happens in systems that use scheduling algorithms to determine which process gets access to the processor.
- The process that is continuously denied access to the processor is said to be starving.
- Starvation can occur due to various reasons, such as:
- Inefficient scheduling algorithms that prioritize certain processes over others.
- Resource limitations, where a process requires a specific resource that is not available or is being monopolized by other processes.
- Starvation can have negative impacts on system performance, as it can lead to delays and decreased efficiency.
- To address starvation, it may be necessary to adjust scheduling algorithms or allocate resources more fairly among processes.
- Overall, starvation is a situation that can occur in systems where processes compete for resources, and it can impact the overall performance and fairness of the system.

Starvation
Starvation refers to a situation in which a process is ready to execute but is continuously denied access to a processor in deference to other processes. This can happen when a scheduling algorithm gives priority to certain processes, causing other processes to wait indefinitely for their turn to execute.
Causes of Starvation
- Priority scheduling: If a scheduling algorithm always selects processes with higher priority to run first, lower priority processes may starve and never get a chance to execute.
- Resource contention: When processes are competing for limited resources such as CPU time, memory, or I/O devices, some processes may be starved if they are unable to access the required resources.
Effects of Starvation
- Reduced system performance: Starvation can lead to decreased overall system performance due to certain processes being denied access to resources for extended periods.
- Unfairness: Starvation can be seen as unfair if certain processes are consistently given priority over others, leading to some processes being deprived of necessary resources.
Preventing Starvation
- Fair scheduling algorithms: Implementing scheduling algorithms that prioritize fairness over strict priority can help prevent starvation by ensuring that all processes eventually get a chance to run.
- Resource allocation: Properly managing and allocating resources within the system can also help prevent starvation by ensuring that all processes have access to the resources they need to execute.
In conclusion, starvation is a critical issue in process scheduling that can negatively impact system performance and fairness. By implementing fair scheduling algorithms and effectively managing resource allocation, starvation can be mitigated to ensure a more equitable distribution of resources among processes.
