Challenge Problems
Push your limits with challenges.
Question 1
Suppose a fixed-partition memory allocation system has 4 partitions (8MB, 10MB, 12MB, and 14MB). If three processes request 9MB, 5MB, and 10MB, respectively, determine which processes can execute and how much memory is wasted due to fragmentation.
💡 Hint: Think about how each process fits into the partitions available.
Question 2
A dynamic memory allocation system with variable partitions has processes arriving that require 3MB, 7MB, and 11MB in that order. If the memory starts as a single block of 30MB, how would fragmentation affect future allocations if a process requiring 5MB arrives later and one of the 11MB processes exits?
💡 Hint: Consider the state of memory after each allocation.
