They actually move bits of data in and out of the CPU/ram once per ‘tick’ of the system-wide clock, which is usually ticking in the GHz range.
Software will handle decisions on what bits/bytes to move where, the registers are where data is electronically modified, the shifters actually move the bytes in and out.
Gonna guess this is related to what he’s talking about: https://en.m.wikipedia.org/wiki/Shift_register
