Non-Contiguous Memory Allocation Quiz

Questions and Answers

Match the memory management technique with its description:

Segmentation = Logical address space of a process can be noncontiguous Paging = Divide physical memory into fixed-sized blocks called frames

Match the hardware component with its function:

Segment-table base register (STBR) = Points to the segment table’s location in memory Page table = Translate logical to physical addresses

Match the term with its meaning:

External fragmentation = Difficulty managing variable-length segments in secondary storage Internal fragmentation = Wasted space within a page or a segment

Match the address translation component with its purpose:

Page number (p) = Used as an index into a page table Page offset (d) = Combined with base address to define the physical memory address Signup and view all the answers

Match the example with the correct memory management concept:

Segmentation Example = Finding the physical memory address for a given logical address based on segment details Paging Example = Mapping logical addresses to physical addresses for a process with fixed-sized pages Signup and view all the answers

Match the term with its usage in memory management:

Frames = Divide logical memory into blocks of same size called pages Segments = Allocating physical memory whenever it is available Signup and view all the answers

Match the memory management scheme with its description:

Contiguous Memory Allocation = Partition the program into a number of small units, each of which can reside in a different part of the memory Non Contiguous Memory Allocation = Segment the program into logical units that can be located in different parts of memory Signup and view all the answers
