Virtual memory does not physically exist while physical memory does.
Where there is not enough physical memory available for the required application, the application and its data are staged through the physical memory with the excess mapped onto a section of hard disk drive. Using this technique the memory appears to be bigger that it actually is (although it is slowed down by the staging process). The bit on the disk is called the virtual memory.

What is deffernce between virtual and physical memory?
The difference between virtual and physical memory is that virtual memory refers to memory space while physical memory are chips like RAM. The memory space for virtual memory is made by operating system when there is insufficient physical memory.
What is the difference between bitween pagefile and virtual memory?
pagefile is the virtual memory
What is the difference between swap and virtual memory?
Swap slices are used as virtual memory storage areas when the system does not have enough physical memory to handle current processes. The virtual memory system maps physical copies of files on disk to virtual addresses in memory. Physical memory pages which contain the data for these mappings can be backed by regular files in the file system, or by swap space. If the memory is backed by swap space it is referred to as anonymous memory because there is no identity assigned to the disk space backing the memory.

Under Windows 2000XP physical memory and virtual memory are both managed by what?
Virtual Memory Manager
What is the difference between physical memory and available memory?
Physical memory is how much total memory your computer actually has. Available memory is what memory you have that is not being used.
What are the implications of having a machine with 48-bit virtual addresses and 32-bit physical addresses?
Having a machine with 48-bit virtual addresses and 32-bit physical addresses means that the system can address a larger amount of virtual memory than physical memory. This can lead to potential issues with memory management, such as increased overhead for address translation and the possibility of running out of physical memory space. It may also impact the efficiency and performance of the system, as the mismatch between virtual and physical memory sizes can result in slower data access times.
Why is physical memory better than virtual memory?
Physical memory (in a computer) is 'better' than virtual memory because it is much faster (and speed is usually the main concern in this subject area). Physical memory (or RAM) is where the programs and variables are stored whilst they are working. Virtual memory is only used when the computer runs out of physical memory. Virtual memory is just one or more files saved on a hard disk. Access to the hard disk is much slower than access to the physical memory.
What is the formula to find the Virtual memory page table?
1.5 of physical memory
Is it ever advisable to have a virtual memory size that is smaller than the physical memory size?
No, it is not advisable to have a virtual memory size that is smaller than the physical memory size. This can lead to performance issues and may cause the system to run out of memory, resulting in crashes or slowdowns. It is recommended to have a virtual memory size that is equal to or larger than the physical memory size to ensure optimal system performance.
The virtual memory addressing capability of 80386 is?
NONE! The 80186 was an advanced version of the 8086 but did not include support for virtual memory. It had a 64K physical address space. The 80286 was the first Intel CPU to support virtual memory but it's capabilities were limited.
