Before RAM had such wide-spread usage, two of the most important parts of a computer were the microprocessor (CPU) and storage (Hard Disk, or in many cases, just a Floppy Drive). However, microprocessors were much faster, and could not reasonably operate near their full potential because they had to 'wait' for the downright sluggish storage drive to send it data.

Random Access Memory (RAM) acts as a high speed middleman, providing enough data from the hard disk for microprocessor to use at any given time without making it wait.
