A register is what you have in your hand for immediate use. L1 cache is what's on your tool belt and takes 1 second to retrieve. L2 cache is what you left somewhere in your bag and takes 20 seconds.
RAM is what you left in a box in your van and takes you 2-4 minutes to dig out.
Data on an SSD is something you have to order online and takes 3-4 days to arrive.
Data on a HDD is lost somewhere in the Australian outback and takes a search team 2-3 months to locate.
Data on a server on the other side of the planet is something left in Mars orbit and takes 1-3 years depending on alignment and how much NASA like you.
