An Overview of Ethernet Hub
Ethernet hub refers to an electronic gear that runs a computer internet.
It is simple and can be configured easily.
It acts like a repeater.
Ethernet hub is also called active hub, data pipe hub, multiport repeater, or simply hub.
It contains multiple input/output ports.
That is to say all devices in this data pipe will receive all the data.
The Internet hub doesnt operate Ethernet traffic.
Plenty of hubs have LED signal lamps that can show the state of the hub.
A collision usually shows up when two or more devices on the same internet attempt to send packets simultaneously.
This phenomenon is called half-duplex communication.
It can cause data holdups, collisions, and online grid slowdown.
Once the collision happens, all of the devices have to go through a routine to fix the conflict.
This process is configured in the Ethernet Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol.

The data pipe hub cannot differentiateMAC addressesas it doesnt have the required software to recognize specific targets.
In essence, the Ethernet hub is an unintelligence machine.
Each incoming bit is copied on all other interfaces.
The Internet hub is the easiest and least way to build computers within a same data pipe.
Ethernet hub also has its drawback.
For instance, it has unnecessary traffic because of the spammy transmission process.
Where is the Ethernet hub used for?
To sum up, it has 3 applications.
An Internet hub caninsert a protocol analyzer into a web link connection.
Hence, the hub is regarded as an alternative to a connection tap or port mirroring.
The online grid hubprevents a loopby accidentally connecting two ports together.
This operation may cause issues when switches are used.
It can work on physical layer of OSI.
Now, you may have an overall understanding of Internet hub.
