LAYER 1 – The PHYSICAL Layer




LAYER 1 – The PHYSICAL Layer


  Converts bits into electronic signals for outgoing messages
  Converts electronic signals into bits for incoming messages
  This layer manages the interface between the computer and the network medium (coax, twisted pair, etc.)
  This layer tells the driver software for the MAU (media attachment unit, e.g. network interface cards (NICs, modems, etc.))  that what needs to be sent across the medium
  it is the bottom layer of the OSI model.






The physical layer is responsible for movements of
individual bits from one hop (node) to the next.
(hope to hope delivery)
