can process and transfer data in the second layer or the data link layer of the OSI model. Switches can also use routing which makes them be referred to as multilayer switches or third layer. A layer 2 switch or second layer is a network bridge that operates in the data link layer. A layer 2 can connect several small devices at work or at home. This is accomplished by having the bridge acquire the MAC addresses for all of the connected devices. Layer 2 differs from standard routers in this since

are true about the commonly used version of the TCP/IP model as shown in this chapter? (Choose two answers.) a. The application layer sits immediately above the network layer. b. The data link layer sits lower in the model than the transport layer. c. The physical layer sits just below the data link layer. d. The network layer sits in the middle of the five layers. 6. The TCP/IP model refers to standards other than those the IETF defines in RFCs. Which of these standards

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

that each layer needs to have two opposite tasks. The second principle dictates that the corresponding layers should be identical. The section ends with a brief discussion of logical connection between two identical layers in protocol layering. Throughout the book‚ we need to distinguish between logical and physical connections. Chapter 2: Objective (continued) The second section discusses the five layers of the TCP/IP protocol suite. We show how packets in each of the five layers (physical

security measures that are associated with each level of the Open Systems Interconnect (OSI). Physical layer This layer is responsible for moving raw bits from one node to another: electrical impulse‚ light or radio signals. This layer represents the physical application security. It includes access control‚ power‚ fire‚ water‚ and backups. Many of the threats to security at the Physical layer cause a Denial of Service (DoS) of the enterprise application‚ making the application unavailable to enterprise
