What is a starvation problem in an operating system?

P Sri Naimisha

Starvation happens if a method is indefinitely delayed. This can emerge once a method needs a further resource for execution that isn’t assigned.

These resources are things like:

  • CPU time
  • memory
  • disk space
  • network bandwidth
  • I/O access to network or disk

Starvation is the problem that occurs when low priority processes get jammed for an unspecified time as the high priority processes keep executing.

A steady stream of higher-priority methods will stop a low-priority process from ever obtaining the processor.

Measures to handle starvation

  • The resource allocation will be taken by a freelance manager to ensure even distribution.

  • Random choice of processes for resource allocation or processor allocation ought to be avoided as they encourage starvation.

  • The criteria for priority of resource allocation ought to take into account factors like agingwhen the priority of a method is hyperbolic it waits longer to prevent starvation.

Differences between Starvation and Deadlock

Starvation Deadlock
1. It is called lived stock. 1. It is called circular waiting.
2. Starvation occurs when a process requires a resource for execution that it is never allowed. 2. A deadlock occurs when two or more processes need some resource to complete the execution held by the other process.
3. Starvation is more of a scheduler issue. 3. Deadlock is more of a process design/distributed design issue.
