The osi layer model was made as an effort to divide the process of communication into a number of steps, so every step could tackle some of the needed functions of the transmission separately let me use a very strange analogy. In the osi model each layer talks to the corresponding layer on the destination node, this is because each layer appends control information to the data from the layer above and the layer on the node that reads it. The osi model has many similarities to the tcp/ip model from a basic conceptual perspective it has (seven) layers, and each layer defines a set of typical networking functions as with tcp/ip, the osi layers each refer to multiple protocols and standards that implement the functions specified by each layer.
The osi model is a concept that breaks down communication between two computers on a network type in a layered process, where each layer will efficiently handle its portion of this process until information is exchanged as desired by the user. Here's the latest free tutorial, with embedded video of yours truly and my favorite analogy: the fedex analogy to explain the osi layers, what each layer does and how they work together in protocol stacks. Even though the osi model utilizes the tcp/ip protocol, the model was originally designed by the open systems interconnection group to promote the osi protocol in its attempt to create a standardized network architecture for network communications. The idea was that tcp/ip was an interesting experiment, but that it would be replaced by protocols based on the osi model as it turned out, tcp/ip grew like wildfire, and osi-based protocols only caught on in certain segments of the manufacturing community.
If any of you knowledgeable persons would offer up a succinct summary of the each of the 7 osi layers assume an audience that's almost child-like in its ignorance, ie, layman's terms are great, but if you can dumb it down even further, so much the better. The osi reference model became the primary architectural model for communications although other architectural models haveshow more content it determines which physical path the data takes, based on the network conditions, the priority of service, and other factors. Read this essay on osi model and tcp/ip model come browse our large digital warehouse of free sample essays get the knowledge you need in order to pass your classes and more. The reference osi layers model (from now we'll just call osi model for short) is a very common term in computer networks and wireless systems, and its understanding can be considered as a requirement for those wishing to understand well the subject.
The tale of two kingdoms how osi layers work tales of two kingdom • would it be nice if some one asked you how does network works and you. 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. The osi model, however, is a proven concept that is used in all other data communications protocols it will continue to be used as a guideline for all other communications applications references. This free lesson is part of teracom's online course osi layers and protocol stacks this course is part of the ctns certification package, a set of six courses plus telecommunications certification organization (tco) certified telecommunications network specialist certification.

For it professionals, the seven layers refer to the open systems interconnection (osi) model, a conceptual framework that describes the functions of a networking or telecommunication system. The osi network stack: an analogy leave a reply since i moved into writing networking software a couple of years ago, i've read quite a few books to try and get myself up to speed with it. A given layer in the osi model generally communicates with three other osi layers: the layer directly above it, the layer directly below it, and its peer layer in other networked computer systems the data link layer in system a, for example, communicates with the network layer of system a, the physical layer of system a, and the data link.
The open systems interconnection basic reference model (osi reference model or osi model for short) is a layered, abstract description for communications and computer network protocol design, developed as part of the open systems interconnection initiative. Salman rusdie illustrate socrates gadfly analogy introduction the time span 'gadfly' is usually pejorative and is often bestowed by associations or persons who are on the getting end of the gadfly's attentions.
24 we use the bob and alice analogy to describe the function of the osi network protocol in a way that does not encumber the readerwith the details of. Iso osi 7 layer model forced with tcp/ip the iso (international standards organization) is a collection of people that are technicians, politicians, lawyers, and members of corporations representing the political / economical / strategic / technical needs of their represented unit. Osi model question 1 network please respond to the following: • you have been assigned the task of writing your own analogy for the osi model. That analogy does show a dependent relationship, but it implies that http is the payload (or the data content), when actually it's another (higher-level) protocol and water is a poor choice for a medium since the data is not transmitted as a continuous bit stream.
