Network nodes and communication links
Network nodes: end nodes and forwarding nodes, which mainly include user hosts and user terminals
                                             Forwarding nodes mainly include switches, hubs, and interface information processors
Communication links: telephone lines, coaxial cables, radio lines, etc
Resource subnets: User hosts and endpoints
Communication subnet: Forwarding node and communication link
Forwarding nodes are commonly referred to as interface information processors (IMPs)
The communication method used by the WAN is called storage-forwarding communication
The communication method used by the LAN is called the broadcast communication mode

The communication method used in the WAN is called storage-forwarding communication---------------------- which is used for storage forwarding through cross-network segment communication through routers, and the LAN of multiple routers is also storage forwarding
The communication mode used in the LAN is called broadcast communication mode---------------------- and link layer Ethernet communication is the broadcast mode. Ethernet is not the same as a local area network
