OSI and Wireless Technologies

The Open Systems Interconnection (OSI) is the primary architectural model in computing. The OSI model is comprised of seven layers which represent the seven different functions of computing. These layers are as follows: application layer, presentation layer, session layer, transporting layer, network layer, data link layer, and the physical layer (Geier, 2005). Each of these layers focuses on specific jobs and is explained further within this writing.

It is important when setting up systems using this OSI model that one considers the various component or hardware that is needed to properly compose a successful operating system. Things such as wireless networking that has overlapping elements are carefully designed to ensure the customer receive the maximal computing systems available.

OSI is a concrete structure of principles for contact in the network across dissimilar devices and applications by unlike retailers. It is currently thought of as the most important architectural model for inter-computing and internetworking communications. Most of the network communication protocols being used at the present have a formation based on the OSI model. The OSI model is divided into 7 layers (Geier, 2005). To make task groups more manageable the layers are then separated into tasks mixed up with moving information between networked computers into seven smaller ones. A job or collection of jobs is next given to each of the seven OSI layers. Every layer is logically self-sufficient therefore the job that is given to each layer can be applied separately. This allows the results obtainable by one layer to be updated with no harm affecting the other layers.
