Question 1

What does the First-Fit strategy do?

  • Allocates the first found suitable hole.
  • Allocates the largest available hole.
  • Searches for the smallest suitable hole.

πŸ’‘ Hint: Think about the sequence in how holes are searched.

Question 2

Challenge Problems

Push your limits with challenges.

Question 1

Suppose you have holes of sizes [10MB, 20MB, 5MB, 30MB] and requests of sizes [12MB, 25MB]. How would each strategy allocate the requests?

πŸ’‘ Hint: Map out each allocation step-by-step.

Question 2

Evaluate the effectiveness of using the Worst-Fit strategy in a real-time system where rapid allocations and deallocations are common. What could be the consequences?

πŸ’‘ Hint: Consider both short-term benefits and long-term ramifications.
