Layman View of OSI Reference Model (By Diganta Deka‚ Former Student‚ Proprietor-Trainer East India Technologies‚ Guwahati.)‚ diganta.deka@hotmail.com When we talk about computer networks and how computers operate in networks‚ things do not remain as simple as it seems to be. Here numerous protocols work in tandem for the sake of data integrity during the course of data transfer. To make things worse there are a lot of vendors in the market who provide and produce great number

The 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 of

Introduction to the OSI Reference Model The International Organization for Standardization (ISO) defined the Open Systems Interconnection (OSI) reference model to standardize networking of devices from different vendors. The OSI reference model is mostly an architecture blueprint that networking and computer device manufacturers implement. The OSI model has never been implemented exactly as defined. The TCP/IP protocol stack is the closest implementation available today. Application Layer (7)

Attacks on layer two of the OSI model Seven layers of OSI In 1977 a model called Open Systems Interconnection (OSI) was proposed‚ with the aim to establish an interoperability standard for different vendor products. This model defines several layers related to data transfer‚ from the lowest (physical) to the highest (application) layer. They have a strong dependence upon one another and headers are usually added when traversing from a lower layer to a higher one. The seven layers are: Layer 1 -

Network Design Models IT190-1204A-01 Introduction to IT Individual Project Elaine Thornton October 29‚ 2012 Computer networks consist of communications‚ media‚ devices‚ and software need to connect two or more computer systems or devices. Networks are able to transmit and receive information to improve organizational effectiveness and efficiency. Assuming our company is not peer to peer networking; our company seems to be a server based network side. With a server based network all accounts

The seventh layer of the OSI model is the Application layer. b. Protocols in the Transport layer accept data from the Session layer and manage end-to-end delivery of data. c. True or False: The IP (Internet Protocol) operates in the Transport layer. False d. True or False: Standards help to ensure interoperability between software and hardware from different manufacturers. True e. True or False: Standards define maximum acceptable performance.

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. These layers are‚ application‚ presentation‚ session‚ transport‚ network‚ data link‚ and the physical layer. Each one encompasses a specific part of the process that occurs during the communication. In order to simplify this think of it like sending a package through the

The OSI model has seven layers‚ with each having different types of security responsibilities. The seven layers are application‚ presentation‚ session‚ transport‚ network‚ datalink and physical with control being passed down from layer to layer starting with application. The biggest threat to these layers is through people‚ sometimes known as the 8th layer of the OSI model. Companies should take the time to educate their employees on the security threats that each individual brings to the company
