Virtual memory is used to increase the size of working memory in the system main memory by using the locations in secondary storage such as harddisk.
explain the logical& physical memory
Find a virtual psychic to read your virtual memory.
virtual memory works just like as temporary memory does
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.
Virtual memory, the answer is virtual memory.
Virtual memory was invented in the early 1960s

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.
In order to free up space in memory, an operating system with a virtual memory capability transfers data that is not immediately needed from memory to the HDD; when that data is needed again, it is copied back into memory. That is, when all of the RAM is being used (e.g., if there are many programs open simultaneously or if one very large program is in use), a computer with virtual memory enabled will swap data to the HDD and back to memory as needed, thus, in effect, increasing the total system memory.
Virtual Memory-: Virtual Mem is also known as Swap memory. Swap memory:- Swap mem is the type of memory which allocates by the harddisk in the form of extra RAM for better functioning of the application in the case if you are facing a lack of RAM in order to run that software
