What is Virtual Memory. Virtual memory is a component of most operating systems, such as MAC OS, Windows and Linux. Virtual memory has a very important role in the operating system. It allows us to run more applications on the system than we have enough physical memory to support. Virtual memory is simulated memory that is written to a file on the hard drive. That file is often called page file or swap file.
For psychologists the term memory covers three important aspects of information processing: 1. Memory Encoding When information comes into our memory system (from sensory input), it needs to be changed into a form that the system can cope with, so that it can be stored.. Memory Retrieval This refers to getting information out storage. If we canât remember something, it may be because we are unable to retrieve it. When we are asked to retrieve something from memory, the differences between STM and LTM become very clear. STM is stored and retrieved sequentially.
