Explanation: In a storage hierarchy, faster, more expensive, and smaller storage options are placed closer to the CPU, while slower, less expensive, and larger options are positioned further away.

Explanation: Within a storage hierarchy, 'memory' typically refers to faster, more expensive, and smaller technologies that are readily accessible by the CPU, in contrast to 'storage'.
