            Random access memory is an essence of computer data storage.  The term “Random” refers to an idea that a piece of data may be returned in constant time, where relation to previous pieces of data or physical location does not matter.  The word RAM is frequently joined with volatile types of memory, which is after the power is switched off, the information is lost.  These days, random access memory takes the form of integrated circuits, allowing in any order to access stored data.  An example of writable volatile random access memory is Synchronous Dynamic Ram modules, chiefly used as main memory in servers, workstations and personal computers.

            Random access memory most habitually refers to computer chips that store, temporarily, dynamic data that augments computer performance.  Faster than retrieving data from the larger hard drive, the computer accesses data by storing active or commonly used files in random access memory.  Random access memory may also be used in other devices, such as printers.  The difference between RAM’s volatile memory and non-volatile memory is that non-volatile memory does not impose for a power source to be necessary to retain data, where RAM loses its contents once power is cut off.  All data located on random access memory is placed into permanent storage on the flash drive or hard drive, when a computer is shut down correctly.  Along with files opened by the user, RAM commences to fill programs automatically loaded at startup, at the computers next boot-up.

            Random access memory is the place in a computer where the data in current use, application programs and operating system are kept so they can be quickly obtained by the computer’s processor.  A CD-ROM, floppy disk, and hard disk, are much slower to read from than RAM.  Random access memory can be compared to a person’s short-term memory in that it focuses on the work at hand but can only keep so many ideas and facts at one time.  If the short-term memory is filled sometimes it is able recover facts stored in long-term memory.  Unlike a hard disk which can become completely full, RAM never runs out and keeps operating but quite possibly much slower than you would prefer.
