uestion 2.1) Explain the difference between deadlock prevention" and "deadlock detection and recovery". 22) Explain the difference between wait/Die" and wound/wait" techniques for deadlock prevention. 2.3) Given the following schedule, draw the wait-for graph. Is there a deadlock? T4 T1 Lock-S (A) R (A) T2 T3 Lock-X (B) W (B) Lock-S (B) Lock-S (C) R (C) Lock-X (C) Lock-x (B) Lock-x (A) 2.4) Consider the following two transactions T1 and T2: T1: R(X WIX) RY WCY Commit T2: R(Y) W(Y) R(X) W(XCommit Show a schedule for T1 and T2 operations that leads to a deadlock when you use exclusive/shared locking (i.e., 3-state locking). Draw the wait-for graph for your chedule
