Question

In a system employing a memory management strategy that doesn't require an entire process to be in main memory at one time; the portion of a process that is actually in main memory at any given time is defined to be the resident set of the process.

	True
	False

The modify (M) bit is a control bit in a page table entry that indicates whether the contents of the corresponding page have been altered since the page was last loaded into memory.

	True
	False

The task of subdividing and allocating memory between the O/S and processes is performed automatically by the O/S and is called:

	Protection
	Relocation
	Memory Management
	None of these are the correct term

The problem of internal fragmentation can be lessened in systems employing a fixed-partition memory management scheme by using:

	Random size partitions
	Equal size partitions
	Unequal size partitions
	None of these will lessen internal fragmentation in fixed-partitioning

The situation where the processor spends most of its time swapping process pieces rather than executing instructions is called:

	Paging
	The Principle of Locality
	Thrashing
	None of these are the described situation
