The Working Register in a Microcontroller

In computers, if you can imagine the money that's in the drawer of the register as the value or the contents of the register, then that's what's going on in computer. The working register is basically the countertop at the grocery store, sitting next to the cash register. So it is a place where you can put stuff and you can work on it. You might call it, if I was thinking more psychological,. Like you've got all this memory available, but the working register is where it's like, okay, boom, like you loaded the working register. You're focused on that.
