The following two transactions result in a deadlock. Show through examples how this deadlock can be dealt with or avoided using conservative and basic two-phase locking algorithms. T1 read_lock (Y); read_item (Y); write_lock (X); (waits for X) T'2 read_lock (X); read_item (X); write_lock (Y); (waits for Y)

Is it less costly to prevent deadlocks than to enable deadlocks and later discover their existence?
Concurrent Processes: Select all of the following statements that are true. A critical section is a segment of code in which at least one process has write access to shared data or resources. The operations acquire() and release() of the Mutex Lock API offered by operating systems may be interrupted during their execution. The Peterson Algorithm is a purely software-based solution to the mutual exclusion problem.
It would yield the trade type, the total and the running harmony for each part. Anticipate the basic balance of 0..
The persons who have come to a stop get the required resources as a direct result of the deadlock detection procedure.
When a deadlock has been identified, the requested resources are made available to those who are unable to go forward.
i) occurs? For the transaction sequence given below using WFG detect if dead lock T1 Read(X) T2 Read(Y) T1 Write(X) T2 Read(X) 1 T3 Read(2) i T3 Write(Z) T1 Read(Y) T3 Read(X) 1 T1 Write(Y): ii) Given below the log of transactions, list the actions that need to be performed on transactions (which use immediate update technique) due to crash of the system.
3) Explain deadlock avoidance and starvation. Draw a wait-for-graph for detecting a cycle in the given transactions T1,T2 and T3 considering (Read-Write) or (Write-Read) conflicting parameters. T1 T2 T3 Read lock(P); Read Item(P); Read lock(Q); Read Item(Q); Write lock(P); Write Item(P); Write_item(Q); Unlock(Q); Write_item(R); Unlock(R); Write item(R); Unlock(R); Time
Consider the following lock requests as given below. S1(A), S2(B),X3(A),X2(C),S1(B),S1(C),X2(B) 12(B). X3(A) Note that • S(..) and X(..) stand for 'shared lock' and 'exclusive lock', respectively. • T1, T2, and T3 represent three transactions. • Transactions will never release a granted lock. a. Determine whether there exists a deadlock in the lock requests and explain why in detail supporting all the arguments
A transaction passes through different states when it is initiated.Explain the each state by taking some example transaction to support your answer that when the transaction will be assigned to the specific state.
The issue that has to be answered is under what conditions is it less expensive to avoid deadlocks than to allow them to occur and then identify them after they have taken place?
Suppose that the transactions at a fast-food restaurant during one afternoon are {hamburger, fries, regular soda}, {cheeseburger, fries, regular soda}, {apple, hamburger, fries, regular soda}, {salad, diet soda}, {hamburger, onion rings, regular soda}, {cheeseburger, fries, onion rings, regular soda}, {hamburger, fries}, {hamburger, fries, regular soda}. Find the count and support of {cheeseburger}.
