For 10 points, name this type of storage that permits a user to retrieve data in any order.
The Manchester Small Scale Experimental Machine utilized an early form of this entity known as the Williams Tube. If CPU performance improves faster than this entity can function, a disparity in speed known as a memory wall may arise. One type of this entity must be refreshed periodically and makes use of capacitors; in addition to that dynamic type, this has phase change and static varieties. Modern computers often possess a few gigabytes of storage of this entity, which mainly comes in volatile types that lose the information they contain when a system loses power.
