Course Introduction：Network topology refers to the physical or logical connections between various nodes in a computer network, including computers, servers, routers, switches and other equipment. It describes the layout and interconnection of various nodes in the network, as well as the data flow in the network. transmission path, common network topologies include "star topology", "bus topology", "ring topology", "tree topology" and "mesh topology".

Course Introduction：EfficientNet is an efficient and scalable convolutional neural network structure with automatic model scaling. The core idea is to improve the performance of the model by increasing the depth, width and resolution of the network based on an efficient basic network structure. Compared with the tedious process of manually adjusting the network structure, this method not only improves the efficiency and accuracy of the model, but also avoids unnecessary work. Through the automatic model scaling method, EfficientNet can automatically adjust the size of the network according to the requirements of the task, so that the model can achieve better results in different scenarios. This makes EfficientNet a very practical neural network structure that can be widely used in various tasks in the field of computer vision. Efficient

Course Introduction：Star network topology is a simple and reliable way to connect networks. Suitable for small network environments, especially scenarios that require centralized management and control. However, in large network environments, other types of topologies, such as tree structures or mesh structures, may be more suitable due to better scalability and fault tolerance.

Course Introduction：1. How to repair common faults of network structure? How to repair common network structure failures? In actual work, we often encounter network failures. Most of these failures are caused by connection errors. When a certain node in the network has a problem, the network will be blocked or even disconnected. Therefore, the network topology must be checked and any fault must be dealt with promptly. So how to judge whether the network card connection is correct? If you find that the network card does not have a driver installed or other software is installed, please check whether the network card is properly connected to other computers. If the computer can access the Internet but does not work properly when connected to the switch, you can try to replug the network card and cable to test. When the network is unavailable, we can connect all the network cables on the switch
