Memory, or random-access memory (RAM) is a form of computer data storage. Today, it takes the form of integrated circuits that allow stored data to be accessed in any order (that is, at random). "Random" refers to the idea that any piece of data can be returned in a constant time, regardless of its physical location and whether it is related to the previous piece of data. RAM is used as a place to hold data which is accessed frequently such as the code of running programs or the contents of open files. This helps computers to be more responsive as the most often used information does not have to be constantly fetched from permanent storage (disk).
