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.


Explain the concept of virtual memory and why it is needed?

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.
