Question

To avoid deadlock

a) there must be a fixed number of resources to allocate
b) resource allocation must be done only once
c) all deadlocked processes must be aborted
d) inversion technique can be used

Answer 1

Avoiding deadlocks typically involves strategic resource allocation and priority inversion techniques to prevent circular waits and ensure safe sequences of resource acquisition and release.

Step-by-step explanation:

The question relates to avoiding deadlocks in a computing context, where multiple processes wait for each other to release resources, potentially halting progress.

To avoid deadlocks, a mix of strategies can be utilized. However, simply having a fixed number of resources or aborting deadlocked processes does not inherently prevent deadlocks. Instead, careful resource allocation strategies and the use of priority inversion techniques can mitigate the risks.

Priority inversion is when a lower-priority task holds a resource needed by a higher-priority one, causing the system to temporarily raise the lower-priority task's precedence. Effective deadlock prevention often requires a comprehensive strategy, including but not limited to resource allocation algorithms that avoid circular wait conditions and allow for safe sequences of resource acquisition and release.
