4. Consider a memory system with 4MB space (the contiguous allocation scheme, please refer tp slide 16 of Lecture 11-12) Currently the memory free but contains ((128KB, 64KB) (512KB, 1MB) (2048KB, 256KB) (2560KB, 128KB) (3072kb, 512KB)) where each item (x,y) in the list represents the starting location x and length y of the free partition. Assume that the best fit allocation policy is used in the systems. Now a job of size 160KB is to be loaded to the memory. (20 points)

(a) When the newly loaded job is in execution, what is the base register? ___________

(b) When the newly loaded job is in execution, what is the bound register? __________________

(d) Assume that the system uses the buddy allocation scheme instead of the best fit allocation scheme. One of the partitions in the free list is not possible to have been generated. Which one?
