3. 二层交换机与三层交换机 二层交换机和三层交换机在工作层次上存在差异。二层交换机主要处理MAC层的数据交换，适用于小型网络环境；而三层交换机可以处理网络层的数据交换，具有更强大的路由功能和更高效的转发性能，适用于大型、复杂的网络环境。 4. 固定配置交换机与模块化交换机 固定配置交换机和模块化交换机在扩展性和灵活性上存在差异。固定配置交换机的端口和功能是固定的，适用于小型、简单的网络环境；而模块化交换机具有更高的扩展性和灵活性，可以根据实际需求灵活配置端口和模块，适用于大型、复杂的网络环境。 The Classification and Difference of Switches I. Classification Switches are network devices used to connect different devices in a network. Based on different classification standards, switches can be divided into various types. Common classification methods include: 1. Classification by application field: There are Ethernet switches, fiber switches, wide area network switches, etc. 2. Classification by transmission rate: There are hundred-megabit switches, thousand-megabit switches, ten-thousand-megabit switches, etc. 3. Classification by working level: There are layer 2 switches and layer 3 switches, etc.

4. Classification by structure: There are fixed-configuration switches and modular switches, etc.

1. Ethernet Switch vs Fiber Switch The main difference between an Ethernet switch and a fiber switch is the transmission medium. The Ethernet switch uses copper cables as the transmission medium, suitable for local area network environments; while the fiber switch uses optical cables as the transmission medium, with higher transmission speed and longer transmission distance, suitable for network environments that require high speed and high stability. 2. Hundred-Megabit Switch vs Thousand-Megabit Switch The main difference between a hundred-megabit switch and a thousand-megabit switch is the transmission rate. The transmission rate of a hundred-megabit switch is at the hundred-megabit level, suitable for general office network environments; while the transmission rate of a thousand-megabit switch is at the thousand-megabit level, suitable for network environments that require higher transmission rates, such as large enterprise networks and campus networks. 　　　 　 3. Layer 2 Switch vs Layer 3 Switch 　　　 　 The main difference between a layer 2 switch and a layer 3 switch is their working level. A layer 2 switch mainly handles data exchange at the MAC layer, suitable for small network environments; while a layer 3 switch can handle data exchange at the network layer, with stronger routing functions and more efficient forwarding performance, suitable for large and complex network environments. 4. Fixed Configuration Switch vs Modular Switch 　　　 　 The main difference between a fixed-configuration switch and a modular switch lies in their scalability and flexibility. The ports and functions of a fixed-configuration switch are fixed, suitable for small and simple network environments; while a modular switch has higher scalability and flexibility, allowing flexible configuration of ports and modules according to actual needs, suitable for large and complex network environments. 　　　 　 In summary, different types and configurations of switches have their own
