Task 2

In internal fragmentation, memory is internal to a partition and ____________

• is not being used

• is always used

• none of the mentioned

A solution to the problem of external fragmentation is ____________

• compaction

• larger memory space

• smaller memory space

• none of the mentioned

Another solution to the problem of external fragmentation problem is to ____________

• permit the logical address space of a process to be noncontiguous

• permit smaller processes to be allocated memory at last

• permit larger processes to be allocated memory at last

• all of the mentioned

If relocation is static and is done at assembly or load time, compaction _________

• cannot be done

• must be done

• must not be done

• can be done

The disadvantage of moving all process to one end of memory and all holes to the other direction, producing one large hole of available memory is ____________

• the cost incurred

• the memory used

• the CPU used

• all of the mentioned

__________ is generally faster than _________ and _________

• first fit, best fit, worst fit

• best fit, first fit, worst fit

• worst fit, best fit, first fit

• none of the mentioned

External fragmentation exists when?

• enough total memory exists to satisfy a request but it is not contiguous

• the total memory is insufficient to satisfy a request

• a request cannot be satisfied even when the total memory is free

• none of the mentioned

External fragmentation will not occur when?

• first fit is used

• best fit is used

• worst fit is used

• no matter which algorithm is used, it will always occur

Sometimes the overhead of keeping track of a hole might be ____________

• larger than the memory

• larger than the hole itself

• very small

• all of the mentioned

When the memory allocated to a process is slightly larger than the process, then ____________

• internal fragmentation occurs

• external fragmentation occurs

• both internal and external fragmentation occurs

• neither internal nor external fragmentation occurs
