  OSI seven-layer model

  The idea of layering: to layer the complex content and simplify the application layer, presentation layer, session layer, transport layer, network layer, data link layer and physical layer of the OSI seven-layer model. -data transmission process: 7) the application layer computer converts the data entered by the user into binary and transmits it to the next layer (presentation layer)

  My understanding of Internet architecture

  Internet architecture computer network is a group of computer systems connected by a certain form, which needs the support of four elements, namely, communication lines and communication equipment, computers with independent functions, support of network software, and the ability to realize data communication and resource sharing. Computer network has two reference models.

  Operating system network _ _ network foundation

  OSI seven-layer model OSI: open systems interconnection model, is a relatively complete network architecture. There are seven layers from bottom to top, which are physical layer, data link layer, network layer, transport layer, session layer, presentation layer and application layer. Among them, the first four layers are related to the operating system level and data transmission.

  Detailed explanation of OSI seven-layer model

  The seven-layer model of OSI is explained in detail in the network, and the seven-layer framework model of the Internet (open systems interconnection reference model) constitutes the foundation of the whole network. The seven-layer framework is divided into physical layer, data link layer, network layer, transport layer, session layer, presentation layer and application layer. 1.

  Reference model of network

  (1) OSI reference model: it is divided into seven layers: physical layer, data link layer, network layer, transport layer, session layer, presentation layer and application layer. Each layer has its own set of functions and interacts with the adjacent upper and lower layers. At the top level, the application layer interacts with the software used by the user. OSI

  Hierarchical idea (OSI seven-layer model to TCP/ IP five-layer model)

  As shown in the figure, each layer of the OSI seven-layer model is the corresponding function, and the corresponding data unit unifies the application layer, presentation layer and session layer of the OSI seven-layer model into the application layer in the TCP/ IP five-layer model. The following picture shows the TCP/ IP five-layer model and the corresponding protocol data transmission process of each layer-data encapsulation and solution.
