What is a Hub

We sometimes meet again a few hubs multi-port or hub, not on a network activity, but as a relief on small local networks.

What is a Hub

Little complicated to implement, but difficult, even impossible, for the most part to administer… We can spend a lot of time and pulling hair on these little boxes…

Definition

Ancestor of the switch, the hub is a network device that works on layer 1 of the OSI model. It’s a multiport hub that brings together all of the flow networks on its ports and regardless of the sender hosts / receivers, it returns all of the flow on the network!

Principle of operation

A HUB is that stupidly send frames to all connected devices. Thus, unlike the switch, it does not keep in memory the recipient addresses in a table. It is not designed to decode the packet header to find the MAC address of the recipient.
Establishing a hub so overload the network by sending all frames to all the connected machines.
This is why one can find a hub on a network BUT only as part of a backup plan.

The current use of the hub

Today, the principle of the hub is used in small boxes USB, available from computer resellers, offering us several ports to connect different small equipment. However, the USB is not a physical bus, only the data passing through the hub are passed to the device for which they are intended. Share its operation, so more like a switch to a network hub
