In this process, choosing the right switch is crucial. This article will provide a guide for choosing the appropriate switch for home network upgrades. I. Understanding Basic Knowledge of Switches 1. Definition: A switch is a network device that connects multiple devices and allows them to communicate with each other. 2. Types: Switches can be divided into various types based on port quantity, speed, and functionality, such as Ethernet switches and fiber switches. 3. Performance Parameters: Performance parameters of switches include port quantity, transmission rate, and backplane bandwidth. These parameters determine the connectivity and transmission speed of the switch. II. Choosing a Switch Based on Home Network Needs 1. Determine Needs: First, you need to determine the number and type of devices that need to be connected in your home network. This will determine the number of ports and type of switch you need. 2. Port Quantity: Choose a switch with the appropriate number of ports based on the number of devices in your home network. If you have many devices, it is recommended to choose a switch with more ports. 3. Transmission Speed: Choose a transmission speed based on your home network's usage needs. If you need to transfer large files or engage in high-bandwidth activities such as online gaming, it is recommended to choose a high-speed switch. 4. Functional Requirements: Choose a switch with the appropriate functions based on your home network's actual needs, such as VLAN (Virtual Local Area Network) functionality, QoS (Quality of Service) functionality, etc. III. Choosing the Right Brand and Model
