The OSI model is a model of how a network actually works. The OSI model has seven different layers and is of course, theoretical. Meaning, this model may not be true in every instance, perhaps it can work without a counter part or perhaps not. The layers of the OSI are comprised of these layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application (InetDaemon, 2015).
The Physical Layer is the layer that is responsible for the hardwired connection, this is in charge of the cables and device layouts (Tetz, 2011). Without this layer no devices would be able to connect to that network. This includes wireless as Wi-Fi cards belong to the physical and data link layers (Capano, 2014). The physical layer also takes the data form the previous layer and converts it into bits to send out, and it also takes bits and converts that into data for the next layer.
The Data Link Layer is responsible for controlling the physical layer (Capano, 2014). It also provide MAC addresses. Every MAC address is unique and it belongs to that particular device. The data link layer i...

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]

Network Architectures, The Osi Model And The Tcp / Ip Reference Model Essay

- 1.4 – Reference Models Section 1.4 is basically the author telling us about two important network architectures, the OSI reference model and the TCP/IP reference model. The OSI (Open Systems Interconnection) deals with connecting opens systems, which are systems that talk with other systems. This model has seven layers: the physical layer, the data link layer, the network layer, the transport layer, the session layer, the presentation layer, and the application layer. From this information, we discover that the OSI model is used only for its model (the 7 layers) and not as a network architecture since it doesn’t specify the exact services and protocols to be used in each layer....   [tags: OSI model, Internet Protocol Suite]

Shedding the Light on the Network, Transport and Application-Layer Protocols of OSI Model

- Executive Summary This report is a response to an individual assignment to partially fulfill the requirements of (TN6384 Computer Network) module. It aims to shed the light on the Network, transport, and application-layer protocols of OSI Model. The report begins with presenting a relevant background to the topic, presenting the historical perspective of OSI protocols. In addition, it explains the purpose and importance of these protocols. Furthermore, it discusses functions and tasks achieved by the seven layers of OSI models followed by presenting the corresponding protocols associated with each layer....   [tags: computer science and data management]

Data Packet Filtering Firewall And A Proxy Server Firewall Essay

- • Now a days TCP/IP is built into the kernels on operating systems. • Packet filtering firewalls get direct support for TCP/IP when kernel is monolithic i.e • If TCP/IP is internal to the kernel it can be executed on the same address space as kernel. • Thus when a new data packet is available on a network interface, kernel can directly process that incoming packet itself, instead of handing over it to a user-level process for processing that packet which is time consuming and slow process. • The primary goal of a packet filtering firewall and a proxy server firewall is to protect a network and both can be used together....   [tags: IP address, Computer network, OSI model]

The Osi Model ( Iso ) Essay

- 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....   [tags: OSI model, OSI protocols, Session Layer]

Security And The OSI Model Essay

- Security and the OSI Model Network security is a topic that reaches far beyond the realm of firewalls, passwords, and user ID accounts. For a network and data to remain secure there must be protective measures at each level in the OSI interconnect model. While each layer basically operates autonomously of the other it is important to ensure that the data being transmitted from the host to destination has not been tampered with or is being prevented from reaching its destination. There are seven level to the OSI interconnect model; each with its own special tasks, abilities, and weaknesses....   [tags: Security Network]

Osi Model And Security : The Open System Interconnection Model Essay

- OSI Model and Security The Open Systems Interconnection Model is a conceptual model describing how any combination of devices can are connected for the purpose of network communication and troubleshooting (Panko & Panko, 2015). Comparing the OSI model’s layers to the levels of application security will shed light on application vulnerabilities. Layer 1 of the OSI model is the Physical Layer. At this layer the OSI model focuses on wires, signals, and repeaters. The security threats are inadequate power, unrestricted access and open wall ports (Holl, 2003)....   [tags: OSI model, OSI protocols, 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]

OSI MODEL Essay

- 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]
