In this section of Operating System Main Memory – Memory Management.it contain Operating System Main Memory – Memory Allocation Using Paging and Segmentation MCQs (Multiple Choice Questions Answers).All the MCQs (Multiple Choice Question Answers) requires in detail reading of Operating System subject as the hardness level of MCQs have been kept to advance level.
PRACTICE IT NOW TO SHARPEN YOUR CONCEPT AND KNOWLEDGE
1. In approaches to noncontiguous memory allocation, the memory can accommodate an integral number of pages. It is partitioned into memory areas that have same size as page. This approach is known as______
- Segmentation
- Paging
- Thrashing
- none of the above
B. Paging
2. Each process consists of fixed size component called _________
- Segment
- Page table
- Pages
- All of the above
C. Pages
3. In which of the memory allocation techniques internal fragmentation can arise
- Segmentation
- Paging
- Segmentation with paging
- All of the above
B. Paging
In paging internal fragmentation can arise because the last page of a process is allocated a page-size memory area even if it is smaller than a page in size.
4. Which of the following non contiguous memory allocation approach have component of different sizes, so that kernel has to use memory reuse techniques such as first-fit or best-fit allocation?
- Segmentation
- Paging
- Segmentation with paging
- All of the above
A. Segmentation
5. In ___________, a programmer identifies component in a process Called_________ in a process.
- Paging, Pages
- Segmentation, Pages
- Segmentation, Segments
- Segment table, Pages
C. Segmentation, Segments
6. Which of the following facilitates sharing of codes, data and program modules between processes?
- Segments
- Page table
- Pages
- Segment table
A. Segments
7. In which of the following memory allocation techniques external fragmentation can arise?
- Segmentation
- Paging
- Segmentation with paging
- All of the above.
A. Segmentation
8. In which of the following memory allocation techniques facilitates sharing of codes, data and program modules between processes without incurring external fragmentation?
- Segmentation
- Paging
- Segmentation with paging
- All of the above
C. Segmentation with paging
9. A process is considered to consists of pages numbered from ______ onward
- -1
- 1
- 2
- 0
D. 0
10. A process is considered to consist of pages. Each pages is of size s bytes, where s is power of ____
- -1
- 1
- 2
- 0
C. 2
