What is the computer network architecture? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Computer network architecture refers to the hierarchical structure model of computer network, which is a collection of protocols and ports between layers. The realization of communication in computer network must rely on network communication protocols. At present, the open system interconnection reference model proposed by the International Organization for Standardization (ISO) in 1997 is widely used.

Computer network architecture refers to the hierarchical structure model of computer network, which is the collection of protocols and ports between layers. The realization of communication in the computer network must rely on the network communication protocol. At present, the Open Systems Interconnection (Open System Interconnection,OSI) reference model proposed by the International Organization for Standardization (ISO) in 1997 is widely used, which is traditionally called the ISO/OSI reference model.

Brief introduction

Computer network structure can be described from three aspects: network architecture (Network Architecture), network organization and network configuration. The network architecture is described in terms of function, which refers to the hierarchical structure model of the computer network and the collection of protocols of each layer, and the network organization is described from two aspects: the physical structure of the network and the implementation of the network. network configuration describes the layout, hardware, software and communication lines of the computer network from the aspect of network application.

Computer network architecture is a precise definition of the functions that should be completed by computer networks and their components. What kind of hardware or software is used to accomplish these functions follows this architecture. The architecture is abstract, the implementation is concrete, and runs on computer software and hardware.

The first network architecture in the world was put forward by IBM Company of the United States in 1974, and it was named system Network Architecture SNA (System Network Architecture). Any device that follows SNA is called SNA device. These SNA devices can be easily interconnected. Since then, many companies have established their own network architectures, which are more or less the same, using hierarchical technology.

After reading the above, have you mastered the method of computer network architecture? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
