at the four protocol layers of the TCP/IP layered model:Layer 1: Network Interface LayerIt contains the protocol used to transfer the IP address data on an existing network medium. In fact, TCP/IP standards do not define functions that correspond to the ISO data link layer and physical layer. Instead, it defines a protocol like Address Resolution Protocol (ARP)

expand the function independently according to the need, meanwhile, it is advantageous to the interconnection of equipment of different manufacturers, and also helps us to learn and understand the data communication network.Different layers in the OSI reference model perform different functions, and each layer communicates with each other through a standard inte

Table 1-1 is the TCP/IP four-layer model and the OSI seven-layer model table. We correspond the OSI seven-layer network model with the Linux TCP/IP four-layer conceptual model, and then categorize the various network

Source: Network Copyright: www.networkdictionary.com The OSI Open System Interconnection model is a reference model proposed by the International Organization for Standardization (ISO) in 1984. As a conceptual standard framework for network communication, this model makes it possible to conduct communication on networks formed by devices and application software of different manufacturers. Now, this model has become a major structural model for commun

to provide standardized application interfaces and public communication services. For example, data format conversion, data compression/decompression, and data encryption/Decryption may be performed in the presentation layer. The application layer contains a large number of commonly needed protocols. This layer handl

Interchange Code (EBCDIC) and the other uses the U.S. Information Interchange Standard Code (ASCII) to represent the same characters. If necessary, the presentation layer enables conversion between multiple data formats by using a pass-through format.7. Application layer: The OSI layer closest to the user. This

The OSI Layer-7 model is complex due to the entire network connection process, including the interconnection between hardware, software data packets, and applications. If you want to write a program that concatenates all functions of the Internet, you must rewrite the entire program when a problem occurs in a small link. Therefore, we divide the entire network in

Introduction to the OSI Layer-7 Model OSI is an open reference model for System Interconnection. It is a well-defined protocol specification. The OSI model has a layer-7 structure, and each layer can have several child layers. Nex
