🔹 A. External fragmentation
🔹 B. Internal fragmentation
🔹 C. Disk caching
🔹 D. File indexing

💡 Difficulty: easy | ✅ Correct: A

Q2. Why is the first‑fit allocation strategy generally faster than best‑fit when placing a new file?

🔹 A. It scans fewer blocks before finding a hole
🔹 B. It requires sorting all holes first
🔹 C. It uses a binary search on hole sizes
🔹 D. It compacts the disk before allocation

💡 Difficulty: medium | ✅ Correct: B

Q3. Compare first‑fit, best‑fit, and worst‑fit allocation strategies. Which statement best captures their trade‑offs in terms of allocation speed and storage utilization?

🔹 A. First‑fit is slowest but uses space most efficiently
🔹 B. Best‑fit is fastest but creates the most fragmentation
🔹 C. Worst‑fit maximizes the size of the largest free hole but often wastes space
🔹 D. First‑fit is generally fastest, while best‑fit and worst‑fit may improve utilization at the cost of speed

💡 Difficulty: hard | ✅ Correct: C
