Physical memory is a set of integrated circuits designed to store binary data. This storage has two characteristic properties: it is transient, as all stored information vanishes when electrical power is lost, and randomly accessible, meaning any bit can be accessed as fast as any other bit. In addition to physical memory, most systems implement virtual memory, which acts to manage physical memory and provide a simple interface to application developers. Virtual memory is consumed by the system kernel, filesystem caches, intimately shared memory, and processes.
