The OSI Model
The Open Systems Interconnection Reference Model or OSI Reference Model for short is a seven layer description for communications and computer network protocol design. It is commonly known as the OSI seven layer model. Its primary feature is to define the interface between layers and to dictate how each layer would interact or communicate to the layer below it and above it. By adhering to these standards, a layer manufactured by one vendor should be able to operate with a layer from a different vendor.
The layers of the OSI model can be divided into Media Layers and Host Layers.
Description of the OSI Layers
Layer 1 - Physical Layer. The OSI Physical Layer "define all the electrical and physical specifications for devices" (Wikipedia, n.d.). The major functions addressed by the physical layer are: establishment and termination of a connection to a communications medium, Ethernet standards and conversions or modulations over a communications medium.......
