Many things besides computers use binary, such as CDs, which have a series of hills and valleys on the surface. These either reflect the light of the thin laser beam shone on them, representing a one, or do not, representing a zero. However these hills and valleys do not directly represent user-accessible data bits. This media-level signal is decoded into 14 bit words that are further decoded into 8 bit bytes of user data by a lookup table (audio data goes through Reed-Solomon decoding after this step). The 8-to-14 encoding (run-length limited) is done to prevent long runs of 1's or 0's at mediMany things besides computers use binary, such as CDs, which have a series of hills and valleys on the surface.
