☆
Which of the following statements on memory management are true?
A
(a) When a CPU needs to access data in DRAM, the DRAM controller verifies the existence of the data. If the data is not found in the main memory, the DRAM controller generates a page fault.
B
(b) In the system adopting paging, when a process is to be executed, its pages are loaded into any available memory frames from their source (a file system or the backing store).
C
(c) In Linux and Solaris, the slab-allocation algorithm uses caches to store kernel objects. When a new object for a kernel data structure is needed, the allocator can assign any free object from the cache to satisfy the request.
D
(d) On Linux which adopts paging, multiple processes can share one page table to save memory consumption.
