Virtual memory (“virtual” means something that is not real) (Joseph, 2007) is an attribute of computer systems in which permanent data storages are utilized in various procedures, thus allowing RAM, or main memory, i.e. “active” or “fast” memory, to be free for other software (Virtual Memory, 2007). If the additional RAM is inserted, the computer system is then able to handle large files and operate with the help of “headroom” memory.
