In a system employing a segmentation scheme for memory management wasted space is due to _______.

External fragmentation

Frames of different sizes

Internal fragmentation

Segments of different sizes

In a system employing a paging scheme for memory management wasted space is due to _______.

Internal fragmentation

Pages of different specified sizes

External fragmentation

In a system employing a segmentation scheme for memory management a process is divided into _______.

One segment per thread

A number of threads

A number of segments which need not be of equal size

A number of segments which must be of equal size

The use of unequal size partitions provides a degree of flexibility to fixed partitioning.

True

False

Programs in other processes should not be able to reference memory locations in a process for reading or writing purposes without permission.

True

False

In a multiprogramming system the available main memory is not generally shared among a number of processes.

True

False

The memory protection requirement must be satisfied by the operating system rather than the processor.

True

False

Any protection mechanism must have the flexibility to allow several processes to access the same portion of main memory.

True

False

A hardware mechanism is needed for translating relative addresses to physical main memory addresses at the time of execution of the instruction that contains the reference.

True

False

In a multiprogramming environment the programmer knows at the time of coding how much space will be available and where that space will be.

True

False

The principal operation of memory management is to bring processes into main memory for execution by the processor.

True

False

A physical address is the location of a word relative to the beginning of the program and the processor translates that into a logical address.

True

False
