Save Digg Del. A networking model , sometimes also called either a networking architecture or networking blueprint , refers to a comprehensive set of documents. Individually, each document describes one small function required for a network; collectively, these documents define everything that should happen for a computer network to work. Some documents define a protocol, which is a set of logical rules that devices must follow to communicate. Other documents define some physical requirements for networking.

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 model uses layers to help give a visual description of what is going on with a particular networking system. This can help network managers narrow down problems Is it a physical issue or something with the application? Conceived in the s when computer networking was taking off, two separate models were merged in and published in to create the OSI model that most people are familiar with today. Most descriptions of the OSI model go from top to bottom, with the numbers going from Layer 7 down to Layer 1.

Introduction to the OSI Model. Compare the layers of the OSI and TCP/IP models. OSI model: • Layer 1—Physical. • Layer 2—Data Link. • Layer 3—Network.

Here are the basic functionalities of the Session layer: The Presentation layer is also called as the layer 6 of the OSI model. OSI Model. The Open Systems Interconnection OSI model defines a networking framework to implement protocols in layers, with control passed from one layer to the next. In plain English, the OSI model helped standardize the way computer systems send information to each other. Data encapsulation is also done at this layer.

There are some similarities and dissimilarities between them. The OSI model mainly emphasis on the services, interfaces and protocols; make a clear distinction between these concepts. Conversely, the TCP model is not able to distinctly describe these concepts. When it comes to the OSI model, it supports connectionless and connection-oriented communication over the network layer but in the transport layer, connection-oriented communication is merely allowed. Have a look at the article difference between connectionless and connection-oriented services , for better understanding. Other differences are discussed below. It is a theoretical model which is used for computing system.

Меган сказала, что, если тереть глаза, будет только хуже. Он даже представить себе не может, насколько хуже. Не в силах сдержать нетерпение, Беккер попытался позвонить снова, но по-прежнему безрезультатно. Больше ждать он не мог: глаза горели огнем, нужно было промыть их водой.

The Open Systems Interconnection model OSI model is a conceptual model that characterises and standardises the communication functions of a telecommunication or computing system without regard to its underlying internal structure and technology.
