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.
How does bankers algorithm avoid deadlock It seems a very obvious algorithm where simply the resources whose needs are less than available are given the resources?
step 1: if(need < available) True then, process allocated.. We find new available : old available + allocation step 2: else false go to step 1
What are the deadlock detection algorithms?
Deadlock is a scenario where two or more processes are blocked, each waiting for the other to release the necessary resources to complete their execution. This situation can cause the entire system to become unresponsive, leading to reduced performance and potentially crashing the system. To avoid this, it is essential to have an effective deadlock detection algorithm in place. Several deadlock detection algorithms are used in modern computer systems. These algorithms use different approaches to detect deadlocks, and each algorithm has its strengths and weaknesses. Wait-for Graph Algorithm: The wait-for graph algorithm is a commonly used deadlock detection algorithm. In this algorithm, a directed graph is created, where the nodes represent the processes, and the edges represent the resources they are waiting for. The algorithm checks if there is a cycle in the graph. If there is a cycle, there is a deadlock in the system. The wait-for-graph algorithm has a few limitations. It can only detect deadlocks and does not provide any mechanism to recover from them. Also, the algorithm may only work well in large systems with a few resources. Resource Allocation Graph Algorithm: The resource allocation graph algorithm is another widely used deadlock detection algorithm. This algorithm creates a graph where the nodes represent the processes and the resources they hold or need. The algorithm checks for cycles in the graph. If there is a cycle, there is a deadlock in the system. The resource allocation graph algorithm is easy to implement and provides an efficient way to detect deadlocks. However, the algorithm requires considerable memory to store the graph, and it can be slow in large systems. Banker's Algorithm: The Banker's algorithm is a resource allocation and deadlock avoidance algorithm. In this algorithm, each process is given a maximum limit on the number of resources it can use. The algorithm checks if granting the requested resources will result in a safe state or not. If the state is safe, the resources are allocated to the process. If the condition is unsafe, the process is put on hold. The Banker's algorithm is an efficient way to prevent deadlocks. However, it requires considerable overhead to maintain the system's state, and it may only work well in systems with a few resources. Ostrich Algorithm: The Ostrich algorithm is a dynamic deadlock detection algorithm. This algorithm assumes a process is deadlocked if it does not progress for a specified period. The algorithm periodically checks the progress of each method and detects if any process is deadlocked. The Ostrich algorithm is efficient in detecting deadlocks in dynamic systems. However, it may not work well in systems where the processes are short-lived, and the algorithm may not detect deadlocks that occur over a short period. Timeout-based Algorithm: The timeout-based algorithm is another dynamic deadlock detection algorithm. This algorithm sets a timer for each resource request made by a process. If the requested resource is not allocated within the specified time, the process is assumed to be deadlocked. The timeout-based algorithm is an efficient way to detect deadlocks in dynamic systems. However, the algorithm may not work well in systems where the processes are short-lived, and it may produce false positives if the time-out period is too short.
What is use of Mutexes?
to avoid deadlock
What is a readers writers problem without deadlock and starvation?
When using threads, the entire point of a reader/writer problem is to avoid deadlock and starvation. The only way to avoid deadlock or starvation without the use of semaphores is for there to be only one possible process that could run, that is one reader and one writer only.
How was Canada's political deadlock solved?
Canada's political deadlock was addressed by forming a coalition government in 1921. This allowed the opposing parties to work together towards common goals and avoid ongoing stalemates in Parliament. The coalition government was led by Prime Minister Mackenzie King and helped break the deadlock in Canadian politics at that time.
What can be implemented to eliminate loops in a switch network?

How deadlock is achieved in java?
A Deadlock is a situation of indefinite waiting where the system is stuck at a particular point and would do nothing useful. For example Method A is waiting for B's input while B is waiting for C's input and C in turn is waiting for A's input. Here all the 3 methods would continue to wait because they are waiting on one another and the system is stuck. A deadlock usually occurs while using threads. Threads can lock objects on which they are processing and when multiple threads are waiting for the same object a Dead lock may occur. The use of the synchronize keyword can be used to avoid such deadlock situations.
