1. Definition: OSI (Open System Interconnection), an Open System Interconnection Reference Model, which logically divides the network protocol into seven layers. Each layer has related and corresponding physical devices. For example, a conventional router is a layer-3 switching device and a conventional switch is a layer-2 switching device. The OSI Layer-7

The OSI reference model has many similarities with the TCP/IP reference model. They are based on the concept of an independent protocol stack. In addition, the features of the layer are similar. For example, in the two models, the transmission layer and above all provide end-to-end and network-independent transmission services for processes that want to communica

OSI Layer-7 Model OSI: Open System Interconnection Reference ModelProposed by ISO in 1984, the objective is to establish a general network standard.

Reasons for the existence of the OSI model (open System interconnection):The network model is built so that the builders of the network can build networks that can communicate and work with each other, and describe the transmission of data from one computer to another on a network.1.physical LayerDefines the electronic and functional aspects of the connection bet

to make a mistake. This layer specifies the topology and provides hardware addressing;Layer 1th Physical layer: At the very bottom of the OSI reference Model. The primary function of the physical layer is to use physical transport media to provide a physical connection to the data link layer for transparent transfer of bitstream.When data is sent, it is transmitted from the seventh layer to the first layer

The OSI Seven-layer model enables reliable communication between different networks of different systems through seven hierarchical structural models, so its main function is to help different types of hosts achieve data transfer.The nodes that complete the relay function are often referred to as trunking Systems. In the OSI seven layer

The OSI Layer-7 model enables reliable communication between different networks of different systems through seven hierarchical structural models. Therefore, its most basic function is to help different types of hosts transmit data. The node that completes the relay function is usually called a relay system. In the OSI Layer-7
