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
Frames of different specified sizes
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
In a uniprogramming system main memory is divided into two parts.
True
False
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
Secondary memory provides fast access at relatively high cost.
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
Overlay programming wastes programmer time.
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
The best-fit algorithm is usually the worst performer.
True
False
All segments of all programs must be of the same length.
True
False
Segmentation does not eliminate internal fragmentation.
True
False
