RAM and active memory
- You'll recall from an earlier episode that computers work through a four stage process to do anything. Input, processing, output, and storage. That second stage, processing, requires a bunch of parts working together, such as the CPU, memory, and the support chips on the motherboard, plus, it requires an operating system to tie everything together. The CPU does the main number crunching. That's the basis for processing. But it turns out that CPUs have almost no memory. Think people, here. Your brain can process information you take in from your input devices, your senses of sight, smell, touch, psychic awareness, and the like, but what happens when you need to process information that you learned about the day before?
