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

Federalism is when power is separated between the National Government and the states. In the constitution it gives certain powers to the National Government and to the states that includes implied powers. The people who wrote the constitution did this to keep the Government from having too much power over the states and the people. There are different types of Federalism that were created for different purposes at different time periods. Cooperative Federalism is when the National Government and

Lab #1 Extraction and Thin Layer Chromatography Kaya Gaudet 6784928 January 9‚ 2013 Line Structure References BenzophenoneBiphenylBenzoic Acid Extraction: A process used to separate different compounds in a mixture based on their solubility in an immiscible substance. Usually an aqueous and organic phase are used. During extraction the desired compound moves one phase and leaves the unwanted substance behind. Extraction normally has to be done a few times to leave all of the impurities

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

1. Physical Layer. Is the physical connection between the sender and the receiver. It includes all the hardware devices (computers‚ modems‚ and hubs) and physical media (cables and satellites). This layer specifies the type of connection and the electrical signals‚ radio waves‚ or light pulses that pass through it. 2. Data Link Layer. Is responsible for moving a message from one computer to the next computer in the network path from the sender to the receiver. This layer has 3 functions: a
