Challenge Problems
Push your limits with challenges.
Question 1
Consider a scenario where a disk has 10GB of space, divided into 512-byte blocks. Suppose the bitmap is full, and you need to allocate a new file of 10MB needing 20 contiguous blocks. Illustrate how the system would handle this request and the potential issues if there were no free contiguous blocks available.
💡 Hint: Reflect on the structure of the bitmap and how it corresponds to the blocks on the disk.
Question 2
Analyze how space consumption might vary in a bit map if the block size were increased to 4KB instead of 512 bytes on a 10GB disk. What impact would this have on the bit map size, and how could this affect performance?
💡 Hint: Consider the relationship between block size and overall bitmap efficiency.
