Why do home networks typically use routers? Repeaters, bridges, and the like? What is the name of a direct link modem for a network?
Bridge: like a smart repeater. Repeaters receive signals from a network cable, amplify them and send them to the next cable. Bridges, by contrast, are more sensitive to the information uploaded from the checkpoint. A bridge is a technique for forwarding frames, isolating collisions according to the MAC partition block. The bridge connects multiple segments of the network at the data link layer.
Repeater: the connection device above the network physical layer. Applicable to the same two types of network interconnection, the main function is to transmit or forward data signals to expand the distance of network transmission. Repeaters are network devices that regenerate and restore signals.
Router: has to judge the network address and select the IP path function, it can in the network environment, the establishment of a flexible connection, data packet and medium access method is used to connect all kinds of completely different subnet, the router accepts only the source station or other router information, an Internet device belonging to the network layer.
