Cheap is its biggest advantage, but because the hub is a shared device, resulting in the heavy network, the efficiency becomes very low, so we can not see the hub in the medium and large network.

A hub is a connection device connected to multiple computers or other devices in a computer network. It is the smallest unit for centralized network management. A hub is a collection of branches, just like the trunk of a tree. Many types of networks rely on hubs to connect devices and distribute data to different network segments. The HUB is basically a shared de

Hub ------- a hub is also called a hub
I. Overview
As its name implies, Hub is the activity center. In network terms, the Hub or Concentrator is a wiring point based on a star topology. Arcnet, 10Base-T, 10Base-F, and many other dedicated networks rely on hubs to connect each segment of cables and distribute data to each segment. The basic function of a hub is information distribution, which distribu
A repeater or hub cannot isolate a conflict domain and cannot isolate a broadcast domain, a bridge or a switch can only isolate a conflict domain from the broadcast domain, and the router can isolate the conflict domain and isolate the broadcast domain.ResolutionThe first thing to know is the conflict domain and broadcast domain, when a piece of network card send information, it is possible to conflict with another NIC network adapter is called the co
A netizen does not know the cat and the router, the hub, the switch difference between them what is different? Computer knowledge Network for everyone to answer:
