Create a document that depict a cluster system connected over a LAN (local area network) and a WAN (wide area network). Include in each layer of the OSI model and clearly depict the communication protocols and devices that operate at each layer. Ensure that the following are represented in :
A cluster where the systems are connected over a LAN.
A cluster where the systems are connected over a WAN.
In the diagram, provide a depiction of communication protocols and devices used at each layer of the OSI model.
