Main Functions A switch is a network device used to transmit data between multiple network nodes. Its main functions include: 1. Data Switching: This is the core function of the switch, which enables the exchange and forwarding of data from different network interfaces, thereby achieving interconnection between various nodes in the network. 2. Connecting Network Devices: Switches can connect various network devices such as computers, servers, routers, etc., allowing them to communicate with each other. 3. Address Learning and Filtering: Switches are able to learn and remember the MAC addresses of devices connected to them, and then filter and forward data packets based on these address information, thereby improving the efficiency of network transmission. 4. Bandwidth Control: Switches can control the bandwidth of network traffic, prevent network congestion, and ensure the stability and efficiency of network operation. 5. Security: Through access control and VLAN (Virtual Local Area Network) technologies, switches can provide certain network security guarantees. II. Application Scenarios Due to the above functions of switches, they are widely used in various network environments. The following are several main application scenarios:
