Memory Management and Virtual Memory MCQ questions form an important quotient in the highly competitive GATE examination as well as in other entrance examinations across the country such as NIELIT, SSC JE and the kind that revolve around the evaluation and assessment of technical studies and the comprehension of STEM concepts in a candidate.The primary purpose of memory management is to offer various ways to dynamically assign different segments of the memory to programs upon their request. Virtual memory, meanwhile, refers to a feature of the operating system that allows a computer to make up for its lack of physical memory. Consequently, one’s familiarity with Memory Management and Virtual Memory syllabus for GATE proves to be a highly vital factor for their preparation for the GATE CS examination.
Important Memory Management and Virtual Memory Topics for GATE CS
The following are the memory management and virtual memory topics for GATE CS and all other branches that form an important part of the memory management and virtual memory GATE syllabus.
Topic | Explanation |
Process | In the field of engineering and computer science, processes refer to that instance of a computer program that is being executed by one or more than one thread. |
Threads | Threads in the field of computer science, |
Demand Paging | In an operating system, demand paging refers to a method of virtual memory management wherein the OS of the system utilising this method copies a disk page into physical memory should that page happen to not already exist in memory. An attempt has been made to access it. |
System Calls | System calls in OS refer to the programmatic manner through which one computer program requests a service from the OS’s kernel on which it is executed. |
