Seven Layers of the OSI Model Kevin Ludwig Bryant and Stratton College TECH 140 Khaled Sabha 12.08.2009 There are seven layers in the OSI model. Each layer has a function or purpose that is used to set up a network. The International Organization for Standardization began to develop the OSI framework in 1984. The purpose was to have each layer interact with the layer directly beneath it. The layers are starting from the top: Application‚ Presentation‚ Session‚ Transport‚ Network‚ Data

The 7 Layers of the OSI Model Last updated: March 03‚ 2008 The OSI‚ or Open System Interconnection‚ model defines a networking framework for implementing protocols in seven layers. Control is passed from one layer to the next‚ starting at the application layer in one station and proceeding to the bottom layer‚ over the channel to the next station and back up the hierarchy. |Application |This layer supports application and end-user processes.

Reference Model or OSI Reference Model or OSI Model is essentially a conceptual description for layered communications and computer network protocol design. It was created as part of the Open Systems Interconnection or OSI initiative. In its most fundamental form‚ it separates network architecture into seven distinct layers: the Application‚ Presentation‚ Session‚ Transport‚ Network‚ Data-Link‚ and Physical Layers. As a result it is frequently referred to as the OSI Seven Layer Model. A layer is a collection

ISO-OSI 7-Layer Network Architecture This lecture introduces the ISO-OSI layered architecture of Networks. According to the ISO standards‚ networks have been divided into 7 layers depending on the complexity of the functionality each of these layers provide. The detailed description of each of these layers is given in the notes below. We will first list the layers as defined by the standard in the increasing order of function complexity: 1. Physical Layer 2. Data Link Layer 3. Network Layer 4.

Checkpoint: OSI Model Paul Tegner IT/242 April 22‚ 2011 Mark Burke OSI Model The OSI Model consists of seven layers. These layers are the application layer‚ presentation layer‚ session layer‚ transport layer‚ network layer‚ data link layer‚ and physical layer. The Application Layer The application layer is responsible for interaction between the operating system and the network services and provides an interface to the system. It provides the user interface to a range

The Five Factor Model was developed by Raymond Cattell as way to describe human personality‚ and disorders. The intention was for it to help personality disorders and to help us improve the general understanding of personality. There have been many models that have risen‚ and some are more accepted than others‚ but the most prominent one would be the five-factor model of personality. The Five-Factor theory is one of the newest models developed for the description of personality‚ and the model shows

THE FIVE –FACTOR MODEL James Baron and David Kreps had given the Five-Factor model‚ which is based on Michael Porter’s Five Forces model of business analysis (Porter‚ 1980). These factors will influence the Competitive Intelligence system in any organization. These factors are External Environment‚ Workforce‚ Organizational Culture and Structure‚ Organizational Strategy‚ and Technology of Production and Organization of Work (Baron & Kreps‚ 1999). Lack of correspondence between any one of these factors

The Five Competitive Forces Model In this section‚ the structure of our company will be explained using the five competitive forces model developed by Harvard professor Michael Porter. These forces include: rivalry among existing firms‚ threat of new entrants‚ bargaining power of buyers‚ threat of substitutes and bargaining power of suppliers. Each of these forces will have their own distinctive effect on determining industry profitability. Intensity of rivalry among competitors: Recently there
