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.
Long-term memory is often divided into two further main types: explicit (or declarative) memory and implicit (or procedural) memory. Declarative memory (knowing what) is memory of facts and events, and refers to those memories that can be consciously recalled (or declared).rocedural memory is sometimes referred to as implicit memory, because previous experiences aid in the performance of a task without explicit and conscious awareness of these previous experiences, although it is more properly a subset of implicit memory.
