1. Which join returns only rows that have matching values in both tables?
INNER JOIN returns only the rows where the join condition is satisfied in both tables.
2. In the context of disk scheduling, what does LOOK differ from SCAN?
Unlike SCAN (which goes to the physical end of the disk), LOOK reverses direction at the last pending request in each sweep.
3. A race condition occurs when:
A race condition exists when the final result depends on the relative timing or interleaving of operations by concurrent processes or threads.
4. Which algorithm solves the all-pairs shortest path problem in O(V³) time?
Floyd-Warshall uses a three-nested-loop DP approach to compute shortest paths between all pairs of vertices in O(V³).
5. What is the purpose of the min-max theorem in game tree search for two-player zero-sum games?
Minimax alternates between maximizing (MAX player) and minimizing (MIN player) nodes to find each player's optimal strategy assuming rational opponents.
6. Which layer of the OSI model is responsible for logical addressing and routing packets across networks?
The Network Layer (Layer 3) handles logical addressing (IP addresses) and determines the best path for routing packets between networks.
