This article is a summary of the questions and topics covered in the GATE-CS-2016(Set 1) examination, specifically for Chapter 56.
Chapter 56 covers the concept of memory management in operating systems. It includes the following topics:
Here are some sample questions that were asked in the exam:
Q1. What is the role of the page table in virtual memory?
The page table is a data structure used by the operating system to store the mappings between virtual addresses and physical addresses. When a program accesses a virtual address, the operating system uses the page table to translate the virtual address to a physical address. This allows programs to access memory that is not physically present in the system.
Q2. What is the difference between paging and segmentation?
Both paging and segmentation are memory management techniques used by operating systems. The main difference between them is the way they divide the memory.
In paging, the memory is divided into fixed-size pages, and each page is independently mapped to a physical frame. In segmentation, the memory is divided into variable-sized segments, and each segment is mapped to a range of physical frames.
Memory management is an important concept in operating systems, and understanding the various techniques used can help programmers write more efficient and effective code. By mastering the topics covered in this chapter, programmers can have a better understanding of how their code interacts with the underlying operating system.
