Communication structures refers to the layout of the existing communication groups and channels. | Communication structures refer to the layout of the existing communication groups and channels. |

We would like to introduce the four best known types of these layouts: | We would like to introduce the //four// best known types of layouts: |

* **Point to Point**: this is the most straightforward. It only involves two participants. It may be ’simplex’, which means that only one of the participants communicates (therefore the process is only a one-way process). It may be ’full-duplex’, which means that the communication partners can equally send information to each other (for example Skype, or Hangouts where the participants can talk simultaneously). | * **Point to Point**: this is the most straightforward.

* **Star-structure**: in this case the whole process is controlled by a main unit and the other participants have to use this main unit in order to communicate with each other. Nowadays modern routers and Wifi works in this way. | * **Star-structure**: In this case, the whole process is controlled by a main unit, and the other participants have to use this main unit to communicate with each other.

* **Bus structure**: the participants have to send their messages through a shared channel (bus). Only one participant can send message at a time; the others have to wait until the transmission is complete. | * **Bus structure**: The participants send their messages through a shared channel (bus).

* **Tree structure**: almost the same as a bus structure, but the whole layout consists of hierarchy levels as well. | * **Tree structure**: almost the same as a bus structure, but the whole layout also consists of hierarchy levels. |

Of course mixed configurations are also well-known in these communication layouts. | Of course mixed configurations are also well-known in these communication layouts. |
