What type of network is made up of hubs?

Networks with hubs as the central node typically adopt a star topology.

In a star topology, all devices are directly connected to the hub node (i.e., hub) through separate links, rather than to each other. When a device needs to communicate with another device, data is transmitted to the central node through the volt-slip link to which it is connected, and then to the target device via the central node. Since each device only needs to be connected to the central node and does not need to be directly connected to other devices, the star topology is easier to manage and maintain, and has good scalability.

However, there are some drawbacks to the star topology. First of all, the central node is the bottleneck of the entire network, and if the central node fails, the entire network will not work properly. Second, the star topology requires a large number of cables and end-to-talk answers, so the cost is relatively high.

The hub in a connected device is called a hub.

The hub is a multi-port device, and when the hub is the central device, even if one line in the network fails, it does not affect the work of other lines. Therefore, HUB has been widely used in local area networks.

Most of the time it is used in star and tree network topologies, with RJ45 interfaces connected to hosts (there are also BNC interfaces), and there are many types of hubs according to different terms. According to the processing method of the input signal, the hub can be divided into passive hub, active hub, and intelligent hub.

Classification of hubs

Passive hub is the lowest level, does not do any processing of the signal, does not extend the transmission distance of the medium, and has a certain impact on the signal. Each computer connected to such a hub receives signals from all other computers on the same hub.

The difference between an active hub and a passive hub is that it can amplify or regenerate the signal, so that it extends the effective transmission distance between the two hosts.

In addition to all the functions of an active hub, the smart hub also has network management and routing functions. In a smart hub network, not every machine can receive a signal, only a computer with the same address as the destination address of the signal can receive it. Some smart hubs can choose the best path by themselves, which is a good management of the network.

Answer] The :d hub is an important tool for centralized network management, like the trunk of a tree, it is the gathering point of each branch. The hub is a shared device, and its essence is a repeater, and the main function of the repeater is to regenerate and collapse the received signal to expand the transmission distance of the network.
