I. Basic Functions A switch is a network device used to connect multiple devices in a Local Area Network (LAN) and achieve rapid forwarding of data packets. Here are the main functions of a switch: 1. Data Forwarding: Switches can quickly forward data packets from source addresses to destination addresses based on the MAC address table, realizing network communication. 2. Network Construction: Switches can connect multiple computers, servers, and other network devices to build a complete LAN. 3. Isolation of Collision Domains: Switches can effectively isolate the collision domains in the network, improving network performance and stability. 4. Filtering Broadcast Traffic: Switches can filter out unnecessary broadcast traffic, reducing network burden. II. Application Scenarios 1. Enterprise Networks: Switches are widely used in enterprise networks to connect workstations, servers, printers, and other devices of various departments, realizing the interconnection of the internal enterprise network. 2. Campus Networks: In campus networks, switches can connect network equipment in various places such as classrooms, laboratories, and libraries, providing convenient network services for students and teachers. 3. Data Centers: In data centers, switches are used to connect servers and network equipment, building an efficient and stable data transmission network. 4. Home Networks: In home networks, switches can expand the coverage of the home network and provide more network interfaces for family members.
