With the advancement of technology, there are various types of switches with their unique features to meet the needs of different enterprises and application scenarios. Below, we will introduce several common types of switches in detail. 1. Managed Switches: Managed switches have powerful management and monitoring functions, supporting network management protocols such as SNMP, and can be remotely configured and managed. They are suitable for large enterprise networks, providing rich management and maintenance functions. 2. Stackable Switches: Stackable switches support stacking of multiple switches, enabling port expansion and bandwidth aggregation, and simplifying the network architecture. They are suitable for data centers, large campus networks, and other scenarios that require high-density ports and high-speed transmission. 3. Wireless Switches: Wireless switches are mainly used in wireless networks, supporting the access and management of wireless devices. They are suitable for enterprises and venues that need to build wireless networks. 4. Fiber Switches: Fiber switches use fiber-optic transmission technology, with features of high bandwidth, low latency, and high reliability. They are suitable for scenarios that require high transmission speed and stability.
