Osi Protocols

OSI Protocol Hierarchy Session Layer The session layer is the fifth among the seven layers of the Open System Interconnections (OSI) model. It resides above the transport layer and below the presentation layer, and provides “value added" services to the underlying transport layer services. The session layer (along with the presentation layer) add services to the transport layer that are likely to be of use to applications, so that each application doesn't have to provide its own implementation...

History of the Osi Reference Model

History of the OSI Reference Model Looking at the origins of the OSI Reference Model takes us back to several issues that were discussed in the Networking Fundamentals chapter of this Guide; specifically, I am talking about standards and standards organizations. The idea behind the creation of networking standards is to define widely-accepted ways of setting up networks and connecting them together. The OSI Reference Model represented an early attempt to get all of the various hardware and software...

Osi Model

describing the OSI model and how it relates to a network. Your response should include answers to the following: • On which layers of the OSI model do WAN protocols operate? • What are some of these protocols? • On which OSI layers do switches and routers operate? • If routers reside at more than one layer, what is the difference between the OSI layers? Introduction: The OSI model was introduced in 1984. Although it was designed to be an abstract model, the OSI model remains...

The Osi Model

The OSI Model NTC/360 Network & Telecommunications Concepts The OSI Model The Open Systems Interconnection Reference Model (OSI) is the accepted model that describes the how the communications for a computer network should be designed. OSI was developed as part of the Open Systems Interconnect Initiative. Basically, OSI divides the functions of a protocol in to seven layers. This makes the reasoning easy to follow and the system much more reliable. The implementation of several OSI layers...

7 Layers of the Osi Model

The 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...

Osi Model

Michael Rauseo IT310 OSI Model In the early years of computer and network research and development many systems were designed by a number of companies. Although each system had its rights and were sold across the world, it became apparent as network usage grew, that it was difficult, to enable all of these systems to communicate with each other. In the early 1980s, the International Organization for Standardization (ISO) recognized the need for a network model that...

Layman View of Osi Reference Model

Layman View of OSI Reference Model (By Diganta Deka, Former Student, Proprietor-Trainer East India Technologies, Guwahati.), diganta.deka@hotmail.com When we talk about computer networks and how computers operate in networks, things do not remain as simple as it seems to be. Here numerous protocols work in tandem for the sake of data integrity during the course of data transfer. To make things worse there are a lot of vendors in the market who provide and produce great number...

Osi vs Tcp/Ip

What is the purpose of an OSI model? The purpose of an OSI model is a standard that was created for networks to share information. This standard governs the way information is transmitted over different networks. The model also sets guidelines to those in the manufacturing industry that create and develop software and hardware that are all compatible with each other. This paper will discuss and describe the 7 layers of the Open System Interconnection model (OSI model) and the layers of the Transport...

Osi Analogy Paper

OSI Model Analogy Trevor Crews Strayer University The OSI model is the model developed for computer-to-computer communications over a network. This model breaks down all the functions that occur into seven distinct layers. These layers are, application, presentation, session, transport, network, data link, and the physical layer. Each one encompasses a specific part of the process that occurs during the communication. In order to simplify this think of it like sending a package through the...
