How does something physical, like a CPU or stick of RAM, move and store non-physical things, such as data?

Question

Computer components are made out of raw materials, like silicon and copper. How does something physical like that create and use things we can’t “see”, like data (0s and 1s)?

Thanks!

A CPU reads 0s and 1s as low and high voltage. A disk sees 0s and 1s as north and south magnetic polarities.

A CD-ROM reflects a laser off shiny aluminium and charred aluminium (“burnt to CD”).
