  Drum memory - Wikipedia, the free encyclopedia
Drum memory was an early form of computer memory that was widely used in the 1950s and into the 1960s.
Drums were later replaced by core memory, which was faster and had no moving parts, and which lasted until semiconductor memory entered the scene.
A drum is a large metal cylinder that is coated on the outside surface with a ferromagnetic recording material.

The terms "storage" (U.K) or "memory" (U.S) refer to the parts of a digital computer that retain physical state (data) for some interval of time, possibly even after electrical power to the computer is turned off.
Historically, "memory" referred to "magnetic core memory" in the 1950s, and then to semiconductor-based storage in the 1970s, at a time when the fastest response times were for magnetic core, and then for semiconductor memory, respectively.
Semiconductor memory (RAM) and magnetic disk are examples of this type of storage.

media categories, for example, semiconductor storage, optical storage, phase change, magneto-optical storage, and magnetic storage, which is mainly disk-based, rather than memory-based.
Each type of storage is suited for different purposes, and most computers contain several types: primary, secondary, and volatile.
It is sometimes referred to as "Main Memory." It can be accessed immediately and randomly.
