ELI5: How can people create working CPU's and Hard Drives inside Minecraft?

I remember reading a while back about a guy who made a CPU inside Minecraft, now I'm reading about another guy making Hard Drive.


What's really going on? How is it possible? Is it working? And what are the limits of what can me made inside the game?

A hard drive just sores information; the guy who created one just made a device that uses the fact that a signal in the game will pass through stone but not glass to create a big grid of cells. Each cell has a stone block and a glass block, and whichever one is put into a certain position stores the piece of data.

The CPU is really just a lot of switches connected together; really, that's all your CPU is. With enough switches of the right kinds controlling each other, any logical operation is possible.

Yes, the hard drive and the CPU both work.

Theoretically, there aren't many limits (except things like the CPU can't run any faster than the CPU of the computer running the game).
