Application Layer Of The Osi Essay - 2375 Words

Q1) Explain the following with examples. a) Data encapsulation process in the OSI reference model in a data communication network Ans) The strategy of passing information by means of layer of OSI called epitome. Marketization is the way toward creating IP bundle. The parcel development handle begins with Layer 7 and stays through Layer 1. Like you sent mail to somebody by means of PC. Begin with the application layer of the OSI/RM the record still to be isolated till the underlying detached document gets to be littler and more controllable bits of data appeared over the transmission standard at the physical layer. A Protocol Data Unit is a bundle of information shaped by a processor and endorsed from one layer of the OSI/RM excessively elective. A PDU holds data correct to every layer. Every layer enhances its own particular information to the parcel. This information permits every layer to join with alternate layers and offer authorization to getting PC to prepare the information. Every layer thinks what has been affirmed down to it from an upper layer to be information. It treats the entire higher-layer message as an information payload. an edge is framed of the exemplification procedure. The following picture demonstrates that how every single layer adds a header to the PDU it takes from the layer overhead it. see that Layer 2 likewise expands a footer additionally there is no header included at Layer 1. the terms information, fragment, parcel and casingShow MoreRelatedApplication Layer 7 Of The Osi Model1254 Words   |  6 PagesRADIUS service: Description The RADIUS also known as Remote Authentication Dial-In Service, which takes place at the application layer also known as layer 7 of the OSI model. It is a protocol that is used to communicate to and from the NAS (Network Access Server) and also to the AAA server. RADIUS was developed as access server authentication and accounting protocol. It is used as both a client and server protocol that is also a software that allows remote access to servers to allow servers to communicateRead MoreOsi vs Tcp/Ip1284 Words   |  6 Pagesis 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 ControlRead MoreCompare and Contrast Tcp/Ip and Osi Models1528 Words   |  7 PagesThe two, OSI and TCP/IP are Standardized Protocol Architectures developed specifically for: 1. Devices to communicate 2. Vendors to have more marketable products 3. Customers to insist on standards based equipment The OSI is a reference model whilst TCP/IP is the suite which is the most widely used. Description of Open Systems Interconnection (OSI Model) Developed by the International Organization for Standardization (ISO) It is made up of seven layers and each layer: 1. performs a subset ofRead MoreOsi Model Essay762 Words   |  4 Pagesdescribing 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 remainsRead More7 Layers of the Osi Model767 Words   |  4 PagesThe 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, NetworkRead MoreThree Layers Of Osi Model843 Words   |  4 Pages â€Æ' Seven Layers of OSI model 1.

The OSI model consist of seven hierarchical layers that defines the path that data must travel. These layers are: Physical, Data Link, Network, Transport, Session, Presentation, and Application. The first and lowest level of the model is the Physical layer. The physical layer consistsRead MoreOsi Model1038 Words   |  5 PagesMichael 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 thatRead MoreBluetooth – Wireless Modus Operandi .

A reference model may be reasonably priced system for comprehension connections. The motivation behind the OSI reference model is to guide sellers and designers that the processed correspondence things and programming programs they create can interoperate, and to encourage clear correlations among specializedRead MoreEssay on Security and the OSI Model1601 Words   |  7 PagesThe Open Systems Interconnect (OSI) model is a standard reference model for the communication between two end users.
