FAQs on Deadlock Prevention Algorithm Video Lecture - Question Bank for GATE Computer Science Engineering - Computer Science Engineering (CSE)

1. What is a deadlock in computer science engineering?
Ans. A deadlock is a situation in which two or more processes are unable to proceed because each is waiting for the other to release a resource. It can occur in a multi-threaded or multi-process environment where each process holds a resource and waits for another resource held by another process.
2. Why is deadlock prevention important in computer science engineering?
Ans. Deadlock prevention is important in computer science engineering to ensure the smooth execution of processes and prevent system failures. By implementing deadlock prevention algorithms, we can avoid situations where processes are stuck in a deadlock and unable to complete their tasks, leading to resource wastage and system inefficiency.
3. What is the purpose of a deadlock prevention algorithm?
Ans. The purpose of a deadlock prevention algorithm is to proactively identify and prevent potential deadlocks in a system. These algorithms analyze the resource allocation and requests made by processes and use strategies such as resource ordering, deadlock avoidance, or resource allocation denial to ensure that deadlocks do not occur.
4. How does a deadlock prevention algorithm work?
Ans. A deadlock prevention algorithm works by analyzing the resource allocation graph and resource requests made by processes. It ensures that the system never enters a state where a deadlock can occur. This can be achieved by enforcing a particular resource allocation order, dynamically allocating resources based on availability, or denying resource requests if they may lead to a potential deadlock.
5. What are some commonly used deadlock prevention algorithms in computer science engineering?
Ans. Some commonly used deadlock prevention algorithms include the Banker's Algorithm, Ostrich Algorithm, and Wait-Die Algorithm. These algorithms employ different strategies to prevent deadlocks, such as resource ordering, dynamic resource allocation, or resource request denial based on process priorities or timestamps. Each algorithm has its own advantages and limitations, and the choice of algorithm depends on the specific requirements and constraints of the system.
