Other network devices other than routers

Hubs, switches, and routers are important devices in computer networks.

Network equipment

Before the emergence of the hub, the first invention is the repeater, which is equivalent to the simplest hub with only two ports, mainly for the extension of the line; before the advent of the switch, the bridge was first invented, it is equivalent to have no The simplest switch with more than four ports is mainly used to block the network's collision domain.

Repeaters and bridges can still be used in current computer networks. Although they are simple in function, they are inexpensive. With the continuous development of science and technology, the performance of network equipment continues to increase and functions continue to expand.

In recent years, with the continuous improvement of three-layer and four-layer switching technologies, three-layer switches and four-layer switches have begun to be widely used in networks.
