Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a situation where a file system using the counting method has a free space representation of: (100, 5), (200, 10), (300, 2). If 7 blocks are allocated starting from block 200, what will be the new free space representation?

💡 Hint: Focus on how the counts are adjusted when allocation happens.

Challenge 2 Hard

Propose a strategy for addressing fragmentation in a file system that uses the counting method. How would you merge adjacent freed blocks?

💡 Hint: Think about how you might identify adjacent blocks in memory.
