Difference Between Deadlock and Starvation in OS

In this post, we will understand the difference between deadlock and starvation in an operating system −

Deadlock

• It is also known as circular wait.

• In this, all processes are waiting for each other to get completed.

• Hence, none of them can execute because they are waiting for the other process to complete.

• Hence, the resources are blocked by the process.

• The necessary conditions for deadlock are mutual exclusion, hold and wait, no pre-emption, and circular wait.

• It can be prevented by avoiding conditions such as mutual exclusion, hold and wait, no preemption and circular wait.

Deadlock n OS:

Starvation

• It is also known as lived lock.

• In this process, the high priority processes are executed, and low priority processes are blocked.

• This means, the low priority process starves due to lack of resources.

• Resources are utilized by high priority process continuously.

• Priorities are assigned to process.

• It can be prevented using the ‘Aging’ technique.
