The OSI model contains up to 7 separate with their own jobs. The layer above is dependant on the layer below to function. If any errors occur on the layers below the higher layers will not be able to function/communication. TCP/IP is a common protocol on the third layer - the Network layer. If the Physical layer is not functioning correctly TCP/IP will not function. It is best to troubleshoot at layer one and move up the list due to the high dependence of the higher layers towards the lower layers.

The history of the OSI layers dates back to the late 1970s. Two projects independently to achieve the same goal. One of the projects to be started by the International Organization for Standardization (ISO) and the other by the International Telegraph and Telephone Consultative Committee (CCITT). In 1983, these two documents were merged to form a standard called The Basic Reference Model for Open Systems Interconnection. The standard is usually referred to as the OSI model. It was published in 1984 by the International Organization for Standardization and Telecommunications Standardization Sector of the International Telecommunication Union (who was previously named CCITT).

Almost all the layers have separate data units, except for layers seven, six, and five (Application, Presentation, and Session). Layers seven, six, and five all use regular data as their data unit. As other layers have their own unique data unit, such as the Network layer uses packets as a data unit. The Data-Link layer uses frames and the Physical layer uses bits. The Transport layer uses segments. The primary reason behind why layers one, two and three have their own unique data units is because they are the media layers. While layers four, five, six and seven ...

...t so happen to run into corrupted data. Corrupted data can be bad for more than just not letting the transport layer succeed at its task, but it can just be a waste of space in general. So try to keep your data safe and clean, because if you don’t your data will end up corrupt and many of the seven layers in the OSI model will not function correctly. If all the 7 layers in the OSI model fail I am for one questioning if you have a PC to even test this out, and I am also concerned about you technology cleanliness.

I hope you learned something about the seven layers in the OSI model in this. I know I did not go over all seven of the layers but if you want to know about the other three layers you can do your own research on those layers. It is not the easiest of topics to grasp but you can learn about the topic if you just keep working towards it and try hard to learn

Essay on The Standard Of The Iso Model

- The ISO model is a model about a network framework to implement protocols in different layers (Seven layers). There are seven layer altogether each layers controls a different part the layers are: Physical, link, network, session, presentation and application layer. Physical layer: the physical layers purpose is communication its job is to transport bits across the network media. A complete frame from the data link is only accepted from the layer. The function of the physical is: bit representation, transmission rate, physical Characteristics, Synchronize, Transmission mode, and Physical topology....   [tags: OSI model, Ethernet, Data Link Layer]

Essay on The 7 Layer Osi Network Reference Model

- 1-Describe the 7-layer OSI network reference model. List all 7 components. The 7-layer OSI network reference model delineates a hierarchy of abstract building blocks that provide basic protocols and services in a logically separated manner for the standardization of networks (Serpanos & Wolf, 2011; Cowley, 2012; Egyedi, 1997). The OSI network reference model was developed by the International Organization for Standardization (ISO) to facilitate communication between networks by keeping certain standards open rather than proprietary (Serpanos & Wolf, 2011)....   [tags: OSI model, OSI protocols, Data Link Layer]

- OSI/ISO Protocols OSI protocol is a network of guidelines for swapping information. Each of these principles of OSI protocols were developed and innovated by the International Organization of Standardization (ISO) which started in the late 1940s. “Since that time ISO has circulated over more than 19,500 international guidelines covering nearly all features of technology and industries across the world in which stated members from ISO” (ISO story). “Today, Geneva, Switzerland, ISO have members from 164 countries and people grind full time for their Central Secretariat” (ISO story)....   [tags: network of guidelines for swapping information]

Essay on The Open Systems Interconnection Reference Model

- The Open Systems Interconnection Reference Model, usually referred to as the OSI Model, it is used to provide a basic framework for networking systems and for how they should work. It is used to help understand, the roles of both hardware and software, networking protocols, and how to troubleshoot network problems. There are seven layers to the model, the physical layer being layer one, the data link layer being layer two, the network layer being layer three, the transport layer being layer four, the session layer being layer five, the presentation layer being layer six, and the application layer being layer seven....   [tags: OSI model, Internet Protocol Suite]

Osi Model Essay

- UNDERSTANDING THE OSI MODEL AND THE RELATIONSHIP WITH TCP/IP The Open Systems Interconnection (OSI) model is a reference tool for understanding data communications between any two networked systems. It divides the communications processes into seven layers. Each layer both performs specific functions to support the layers above it and offers services to the layers below it. The three lowest layers focus on passing traffic through the network to an end system. The top four layers come into play in the end system to complete the process....   [tags: Networks Telecommunications]

- 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 would help companies create common network implementations....   [tags: essays research papers]

OSI Model Essay examples

- OSI Model During the past two decades there has been a tremendous increase in the numbers and sizes of networks. Many of the networks, however, were built using different implementations of hardware and software. As a result, many of the networks were incompatible and it became difficult for networks using different specifications to communicate with each other. To address this problem, the International Organization for Standardization (ISO) researched many network schemes. The ISO recognized that there was a need to create a network model that would help network builders implement networks that could communicate and work together (interoperability) and therefore, released the OSI referen...   [tags: Essays Papers]
