CUET PG 2025 — Computer PYQ

CUET PG | Computer | 2025

Complete the following statement by choosing the correct option.

For a deadlock to occur, the four conditions namely Mutual Exclusion, Hold and wait, No preemption, circular wait_______

Choose the correct answer:

Explanation

Solution:

Deadlock tabhi sambhav hai jab charo Coffman conditions ka intersection (milap) hota hai. Agar hum in charo conditions ko $C_1, C_2, C_3,$ aur $C_4$ maane:

$C_1$ : Mutual Exclusion
$C_2$ : Hold and Wait
$C_3$ : No Preemption
$C_4$ : Circular Wait

Deadlock Occurrence Logic:

\text{Deadlock} \iff (C_1 \land C_2 \land C_3 \land C_4)

Iska matlab hai ki deadlock hone ke liye charo conditions ka ek saath (simultaneously) hona anivarya hai. Agar ek bhi condition break hoti hai, toh deadlock nahi ho sakta:

\neg (\text{Deadlock}) \impliedby (\neg C_1 \lor \neg C_2 \lor \neg C_3 \lor \neg \text{C}_4)

Right Answer:

Must hold simultaneously
