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

This is true because if any bias is present, the outcome may be affected by the scientist's method.
The recovery method that usually involves an evasion effort is the "avoidance" strategy. This approach focuses on minimizing or evading the negative impacts of a situation instead of confronting the issue directly. Individuals or organizations employing this method may seek to withdraw from the problem or divert attention away from it, often to reduce stress or risk. While it can provide short-term relief, avoidance may lead to unresolved issues in the long run.
The recovery method that usually involves evasion is the "avoidance" strategy. In this context, individuals or organizations may sidestep or delay confronting issues, often hoping that problems will resolve themselves over time. This approach can lead to further complications if not addressed, as it typically does not tackle the root causes of the issues at hand.
Non-examples of the word "glutton" would include terms like "moderate," "satisfied," or "restrained." These words describe behaviors or attitudes that reflect self-control and moderation in consumption, contrasting with the excessive indulgence implied by gluttony. Other non-examples might include "abstinent" or "temperate," which emphasize avoidance of excess altogether.

deadlock avoidance
Deadlock avoidance ensures that a system never enters a deadlock state, allowing for continuous operation and resource utilization. Its advantages include increased system reliability and improved resource management, as it proactively prevents potential deadlock scenarios. However, it can also lead to lower resource utilization and increased system complexity, as it requires careful monitoring and management of resource allocation and process states. Additionally, the algorithms used for deadlock avoidance can introduce overhead, potentially affecting overall system performance.
safety algorithm is algo which is used for deadlock avoidance.
Deadlock prevention is the name of the technique that is designed to get rid of deadlocks by changing the specifications of the system , that is the system design change. This is , basically , about how requests about resources are made and how they are permitted. However , deadlock avoidance is a technique that aims to check deadlock possibility dynamically and decides whether it is safe to grant a resource or not. It ,definitely , needs extra information about potential use of resources for each process. Deadlock Prevention: Preventing deadlocks by constraining how requests for resources can be made in the system and how they are handled (system design). The goal is to ensure that at least one of the necessary conditions for deadlock can never hold. Deadlock Avoidance: The system dynamically considers every request and decides whether it is safe to grant it at this point, The system requires additional apriori information regarding the overall potential use of each resource for each process. Allows more concurrency. Similar to the difference between a traffic light and a police officer directing traffic.
Deadlock PreventionDifference from avoidance is that here, the system itself is build in such a way that there are no deadlocks.Make sure atleast one of the 4 deadlock conditions is never satisfied.Deadlock AvoidanceAvoid actions that may lead to a deadlock.Think of it as a state machine moving from 1 state to another as each instruction is executed. moreoverDeadlock detection is a technique to handle deadlocks which tries to find out if the system is in deadlock and then works to recover it from the deadlock if any exists. It is used as an afterthought and is not coordinated with the resource allocating procedures.Deadlock avoidance is a technique which works hand-in-hand with the resource allocation and tries to ensure that a resource request made in a non-deadlocked state is granted only if it will not lead to a deadlock in the future. This technique however makes unrealistic demands about the kind of information it needs from process, in that, it requires the entire pattern of resource requests, past & future.
Deadlock Prevention: o Preventing deadlocks by constraining how requests for resources can be made in the system and how they are handled (system design). o The goal is to ensure that at least one of the necessary conditions for deadlock can never hold. * Deadlock Avoidance: o The system dynamically considers every request and decides whether it is safe to grant it at this point, o The system requires additional apriori information regarding the overall potential use of each resource for each process. o Allows more concurrency. Similar to the difference between a traffic light and a police officer directing traffic. * Deadlock deduction:- Often, neither avoidance nor deadlock prevention may be used. Instead deadlock detection and process restart are used by employing an algorithm that tracks resource allocation and process states, and rolls back and restarts one or more of the processes in order to remove the deadlock. Detecting a deadlock that has already occurred is easily possible since the resources that each process has locked and/or currently requested are known to the resource scheduler or OS. Detecting the possibility of a deadlock before it occurs is much more difficult and is, in fact, generally undecidable, because the halting problem can be rephrased as a deadlock scenario. However, in specific environments, using specific means of locking resources, deadlock detection may be decidable. In the general case, it is not possible to distinguish between algorithms that are merely waiting for a very unlikely set of circumstances to occur and algorithms that will never finish because of deadlock. Deadlock detection techniques include, but is not limited to, Model checking. This approach constructs a Finite State-model on which it performs a progress analysis and finds all possible terminal sets in the model. These then each represent a deadlock.

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.
The antonym for deadlock is agreement.
