FAQs on Deadlock Introduction Video Lecture - Crash Course for UGC NET Computer science
| 1. What is a deadlock in operating systems? |  |
Ans. A deadlock in operating systems occurs when two or more processes are unable to proceed because each is waiting for the other to release a resource, resulting in all processes being stuck in a state of indefinite waiting.
| 2. How can deadlocks be prevented in operating systems? | |
Ans. Deadlocks can be prevented in operating systems using various techniques such as deadlock prevention (ensuring that the conditions necessary for a deadlock cannot occur), deadlock avoidance (ensuring that the system always remains in a safe state), and deadlock detection (identifying and recovering from deadlocks when they occur).
| 3. What are the necessary conditions for a deadlock to occur? | |
Ans. The necessary conditions for a deadlock to occur are mutual exclusion (resources cannot be shared), hold and wait (processes holding resources while waiting for others), no preemption (resources cannot be forcibly taken from a process), and circular wait (a circular chain of processes waiting for resources).
| 4. How does an operating system handle deadlocks? | |
Ans. Operating systems handle deadlocks by using various algorithms such as deadlock detection and recovery, resource allocation graphs, and banker's algorithm to prevent or resolve deadlocks when they occur.
| 5. What are some common examples of resources that can lead to deadlocks in operating systems? | |
Ans. Some common examples of resources that can lead to deadlocks in operating systems include memory, CPU cycles, files, devices, and network connections.
