    OSI Layers 1) Physical Layer: The physical layer is at the bottom of this model. It deals with crude data that is in the form of electrical signals. The data bits are sent as 0s and 1s. 0s correspond to low voltage signals and 1s correspond to high voltage signals. The mechanical aspects of communication‚ such as wires or connectors come under this layer. The physical layer also deals with how these wires‚ connectors‚ and voltage electrical signals work. Also‚ the process that is required for

    Layers and mechanisms: A new taxonomy for the Bullwhip Effect Giovanni Miragliotta In this article‚ Giovanni Miragliotta has two main purposes. The first one is to strengthen the knowledge on the dynamics of a supply chain via a deep review of the Bullwhip Effect. The second one is to build a new framework abled to classify the causes of the Bullwhip effect. Furthermore‚ this framework can distinguish layers and mechanisms that lead to Bullwhip Effect and so help managers to better understand
