I. Key Role 1. Data Transmission and Exchange The main function of switches is to achieve rapid data transmission and exchange. In enterprise networks, various devices need to constantly exchange and communicate data, and switches can quickly receive, process, and forward data packets to ensure smooth data transmission. 2. Improving Network Performance By using switches, enterprises can build an efficient local area network. Switches adopt a multi-port design that can handle multiple data streams simultaneously, greatly improving network performance. In addition, switches support a variety of transmission rates and modes that can be flexibly configured to meet different enterprise needs. 3. Network Security Guarantee Switches also play an important role in network security. By configuring security policies such as Access Control Lists (ACL), switches can monitor and manage network traffic, prevent unauthorized devices from accessing the network, and ensure the security of the enterprise network.
