What is deadlock and explain it?
A deadlock is when both sides can't agree on a decision or when something is stuck and can't move. In technology, a deadlock is a situation where a group of processes are permanently blocked as a result of each process having acquired a subset of the resources needed for its completion and waiting for release of the remaining resources held by others in the same group-thus making it impossible for any of the process to proceed.
What causes Deadlock?
A set of processes is deadlock if each process in the set is waiting for an event that only another process in the set can cause.
What is the difference between deadlock preventation and dead lock detection?
The difference is exactly what you have just stated: deadlock prevention is used to stop deadlocks before they happen (to prevent them), while deadlock detection is used to figure out when a process has deadlocked (to detect it).
What is difference between starvation and deadlock?
Deadlock: Two processes are said to be in deadlock situation if process A holding onto resources required for process B and where as B holding onto the resources required for process A. Starvation: This is mostly happens in time sharing systems in which the process which requires less time slot is waiting for the large process to finish and to release the resources, but the large process holding the resources for long time (almost for forever) and the process that requires small time slot goes on waiting. Such situation is starvation for small process
What are the main limitations to the resource allocation graph used in deadlock detection. explain?
time Stamp
Explain the conditions that results in a deadlock situation?
You choke.
What is Deadlock avoidance?
Deadlock is a situation when two thread are waiting on each other to release a resource. Deadlock avoidance methods are : 1) ostrich approach 2) eliminating hold and wait situation 3) eliminating mutual exclusion

How can you use deadlock in a sentence?
Deadlock as a noun is a situation involving opposing parties, in which no progress can be made for an action or decision. As a verb, deadlock is the act of creating the situation in which no further progress can be made. Example sentences: The family meeting ended in a deadlock for vacationing at the Grand Canyon or Disney World. I'll need a third choice so that the next meeting won't deadlock on the vote.
What are the various strategies are used to handle deadlock and what is centralized and distributed deadlock detection and prevention?
There are four strategies of dealing with deadlock problem:1. The Ostrich ApproachJust ignore the deadlock problem altogether.2. Deadlock Detection and RecoveryDetect deadlock and, when it occurs, take steps to recover.3. Deadlock AvoidanceAvoid deadlock by careful resource scheduling.4. Deadlock PreventionPrevent deadlock by resource scheduling so as to negate at least one of the four conditions.
Sentence using deadlock?
Peacekeepers tried to break the deadlock between the two waring nations, but failed, and the war continued. A deadlock is a situation in which two or more competing actions are each waiting for the other to finish, and thus neither ever does. Search Google for info on deadlock in computers.
What is deadlock protection?
Any scheduled task waiting for an event with waiting queue may result in a situation where wait is indefinitely for a process execution. The stage is termed as deadlocked, and a mechanism or algorithm to avoid such situation is called deadlock protection.
What is Political Deadlock?
Political deadlock is a situation where competing political parties have equal representation in the political system making it impossible for decisions to be made.
What is a situation in which neither side is able to gain ground or achieve victory?
A stalemate.
Why Bankers algorithm to avoid deadlock is called so?
It is called that so that the algorithm will prevent such a financial situation.
Can deadlock be resolved without selecting a victim?
Yes, deadlock can be resolved by avoiding the conditions that lead to it, breaking the circular wait, or using deadlock prevention techniques like resource allocation graph, timeouts, or priority-based techniques. In some cases, deadlock can also be prevented by ensuring a single thread holds all resources simultaneously or by using a deadlock detection algorithm to preemptively handle it.
What is deadlock in rdbms?
A deadlock is a situation in which two or more competing actions are each waiting for the other to finish, and thus neither ever does. In an operating system, a deadlock is a situation which occurs when a process enters a waiting state because a resource requested by it is being held by another waiting process, which in turn is waiting for another resource. If a process is unable to change its state indefinitely because the resources requested by it are being used by another waiting process, then the system is said to be in a deadlock.
