How Hubs Work

By Ace Winget_

Technological devices can be intimidating sometimes.Devices that work or connect with computers always seem to be the worst and most complex.It is like a whole different world trying to understand how they work.

Hubs are very user friendly. They are probably the simplest and most easy devices to understand that is used with computers.They also have the benefit of being inexpensive.

There are many similarities between hubs and switches, but hubs are very simple.Think of hubs as an introduction to switches.The function of hubs has been built into several other devices like routers as time goes on.

The purpose of hubs is to allow multiple computers or devices to communicate with each other. One computer sends information to the hub. When the hub receives it, it copies the information and then sends it to all the other devices.

The hub sends the information through Ethernet cables. There are multiple ports on the hub so that multiple Ethernet cables and devices can connect. This means that only wired networks can use hubs.

Hubs cannot distinguish source or destination addresses of the devices. This is why all of the devices receive the same information. Switches on the other hand of the feature of reading source and destination addresses.

Switches are also capable of receiving and sending information simultaneously. Hubs also receive and send information, but they can only do it one at a time. Hubs are a lot slower than switches because of this.

Devices hook up to the hub in a pattern similar to a spider web. There is the main computer that is connected to the Internet and also connected to the hub. All of the other computers are then just connected to the hub. It is a remarkable and simple process. Hubs are great for small businesses or households.
