IV Chapter 0010: Summary
In this chapter you learned the various layers of the all-important OSI logical network model.
The basic IEEE standards were described as well, with special emphasis on recent gigabit and wireless networking developments. Be aware of the method used by each standard to control traffic, such as collision detection (802.3), collision avoidance (802.11b), token passing (802.4) or time slots (Bluetooth).
The actions that take place within each layer of the OSI model invite further exploration due to the depth and complexity of the model. Focusing on the basics however will lead you to comprehension, especially if you develop a visual image of how each layer must interact with another, receiving data from one adjacent layer and passing it along to the other adjacent layer, for successful data communications. You are encouraged to memorize the layers and the actions in each layer.
From this point it is logical to delve into the hardware that implements many of the functions outlined by the OSI model.
