1. A computer network is centered on multiple geographically dispersed terminals connected to a central computer through communication lines.

It is divided into four generations

2. The first generation computer network is a remote online system centered on a single computer. A typical application is an airplane ticketing system consisting of a computer and more than 2,000 terminals across the United States.

3. The second generation computer network is based on the interconnection of multiple hosts through communication lines to provide services to users. It emerged in the late 1960s. The typical representative is the ARPAnet developed with the assistance of the U.S. Defense Advanced Research Projects Agency.

4. The third generation computer network is an open and standardized network with a unified network architecture and following international standards.

IS0 promulgated 0SI/RM in 1984. The model is divided into seven levels, also known as the 0SI seven-layer model, and is recognized as the basis of a new generation of computer network architecture. It laid the foundation for the popularization of local area networks.
