I've read in some books that the physical layer (L1) of the OSI model deals with the logical functions of putting the 1's and 0's onto a wire and not the physical act of doing so, and I've read other books that state that the physical layer deals with not only putting 1's and 0's onto a wire, but also the mechanical make-up of a wire, the electrical voltage of a wire, hardware,. etc.
