Is every white key on a keyboard is represented by line or space staff?

Not every white key on a keyboard is represented by a line or space of the staff. Each piano key is represented by one pitch which is represented on a staff by a note which is placed on a line or space and is modified by accidentals. The musical alphabet has seven letters A-G, seven white notes C-B, and five black notes which divide the white keys into a semi-tone each.
