Create a PowerPoint® or Apache OpenOffice™ Impress® presentation of at least three slides that depicts a cluster system connected over a LAN (local area network) and a WAN (wide area network). Include in the presentation 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 the presentation:
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.
Drawings may be performed using a presentation tool or exported from Microsoft Visio or Apache OpenOffice™ Draw.
