ccna preguntas y respuestas.01 Introduction to the OSI Reference Model Two-Minute Sprint02 Self-test questions for each layer of the OSI reference model 2.03 Encapsulation and unencapsulationSuccessfully configuring Cisco switches and routers requires an understanding of some of the basic networking concepts outlined in this chapter and some of the advanced concepts that the company will discuss later in the book. The Open Systems Interconnection (OSI) reference model is the best place to start, and it will help you understand how information is transferred between network components. Of the seven layers included in the OSI reference model, you must understand how the next three layers work, because most network components operate at these three layers. Many network engineers believe that Layer 4 should also be included because routers and Layer 3 switches also provide Layer 4 functionality, and troubleshooting a network often requires looking at Layer 4 port numbers to find problems such as access control list (ACL) misconfigurations, which are discussed in Chapter 21. This chapter uses the OSI reference model to illustrate the encapsulation and unencapsulation process, describing how traffic is transported between network components. The encapsulation and unencapsulation process when transferring data between network components using TCP/IP is covered in more depth in Chapter 9.The Authentication Void 2.012-1 Introduction to the OSI Reference ModelIn 1984, the International Organization for Standardization (ISO) developed the OSI reference model to describe how information is transmitted between network components: starting with the user entering information using a keyboard and mouse, and ending with the information being converted into electrical, optical, or radio waves transmitted over cable, fiber optic cable, or air.The OSI reference model describes concepts and terminology in a generic manner, while many network protocols (such as Transmission Control Protocol/Internet Protocol [TCP/IP] and Interconnection Network Packet Exchange [IPX]) are not quite consistent with the situation articulated in this model, and it is important to understand this. With this in mind, the OSI reference model is primarily used as a teaching and troubleshooting tool. Once the basics of the OSI reference model are understood, this knowledge can be applied to actual protocols, leading to a deeper understanding of these protocols and easier troubleshooting. Basically, the OSI reference model provides the foundation for understanding what happens when network components communicate with each other.ISO developed this 7-layer model to help vendors and network administrators gain a deeper understanding of how data is processed and transmitted between network devices, and to provide guidelines for implementing new network standards and technologies. To this end, the OSI reference model divides the network communication process into seven layers.OSI Model.. Defines the processes that connect the two layers to improve interoperability between vendors.. . divides complex functionality into simpler components .. Enabling vendors to design in a modular fashion, simplifying implementation and troubleshooting .
