Virtual memory refers to the combination of your "physical memory" (RAM) and any available "swap file". A swap file is a chunk of your hard drive that the computer sets aside in case your RAM fills up and it needs somewhere to store some extra information temporarily (however swap files tend to be a bit slower as they use a hard drive rather than RAM).
So if you had 2GB of RAM on your PC and Windows made a 2GB swap file, you would have 4GB of virtual memory.

Is cache memory equal to virtual memory?
No! ; Cache memory is integrated in the CPU. Virtual memory is a part of the hard drive that the OS use as ram memory, when running out of real ram memory.
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.
How is data transferred between a CPU and RAM?
A memory management unit (MMU) is a small device between CPU and RAM recalculating the actual memory address, for example to provide an abstraction of virtual memory or other tasks.
Differentiate between the physical virtual and cache memory Explain briefly?
Virtual memory is a type of memory that is allocated by the operating system and is used to speed up operations. Cache memory is RAM that the CPU can access faster than regular ram which is considered physical memory. When the CPU is looking for data, it checks the cache memory first, recently used data will still be in the cache. If it does not find it there, it moves on to use the physical memory. Anytime a program or file is opened, it is first loaded into RAM (physical memory).
When evaluating CPU memory do you check the cache memory?
The only memory on the CPU is cache memory and it is only dependent on the CPU type and generation you use.
How do you read virtual memory?
Find a virtual psychic to read your virtual memory.
How does virtual memory work?
virtual memory works just like as temporary memory does
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.
Where is CPU and memory are located?
output device No The CPU and memory are located on the motherboard
What does the computer use when RAM is full?
Virtual memory, the answer is virtual memory.
When virtual memory is invented?
Virtual memory was invented in the early 1960s
When your computer runs out of ram does it borrow space from the CPU?
If your computer runs out of ram it will use virtual memory, essentially meaning it will borrow space from the hard drive.
