About this document
Overview of Physical Layer Media by Pragati Srivastava is a document available to read on EtoBox.
The physical layer defines the mechanical, electrical, and timing interfaces to transport a raw bit stream from one machine to another. It uses various physical media like guided media such as copper wire and fiber optics, and unguided media such as radio and lasers through the air. Common media include magnetic tape, twisted pair copper wires, coaxial cable, and fiber optics which uses glass fibers to transmit pulses of light for digital data transmission.
