Each process is allocated a table that maps its virtual pages to physical frames.
The abstraction of virtual memory provides a simplified view of memory management to applications, allowing programs to use a large space.
What is the main purpose of virtual memory in modern operating systems?
Address Translation
Page faults slow down performance when accessing data not in RAM, as the system must fetch pages from slower storage.
What illusion does virtual memory create for applications?
Multitasking
Address translation is a crucial process in virtual memory, enabling the system to map virtual addresses to memory addresses.
How does virtual memory help with multitasking?
Each process is given the illusion that it has access to a large and contiguous block of , even if the actual physical memory is fragmented.
By isolating processes in their own virtual address , virtual memory enhances security and reliability, preventing one process from interfering with another.
What is the main purpose of paging in memory management?
By managing memory more efficiently, virtual memory enhances system and multitasking capabilities.
What is the primary purpose of address translation in virtual memory?
Improper management can lead to data , and certain attacks may exploit virtual memory behavior.
Which of the following best describes a page table?
Virtual memory allows computers to use hard drive space as an extension of .
Physical Frames
This creates a large space that can be utilized by applications.
