Osi Model Essay -- Networks Telecommunications

UNDERSTANDING THE OSI MODEL AND THE RELATIONSHIP WITH TCP/IPThe Open Systems interconnection (OSI) feigning is a reference tool for understanding datacommunications between any two networked systems. It divides the communications processes intoseven layers. Each layer some(prenominal) performs specific functions to support the layers above it and offersservices to the layers below it. The three lowest layers focus on passing traffic through the network toan end system. The light up four layers come into play in the end system to complete the process.This presentation lead provide you with an understanding of each of the seven layers, including theirfunctions and their relationships to each other. This will provide you with an overview of the networkprocess, which can then act as a framework for understanding the details of computer networking. Alsothis paper will condone how the 802 specifications expanded the OSI reference model by dividing thedata link layer into two layers.F inally, this paper will draw comparisons between the theoretical OSI model and the usefulTCP/IP model. Although TCP/IP has been used for network communications before the adoption of theOSI model, it supports the same functions and features in a differently layered arrangement.The level of the development of the OSI model is, for some reason, a little-known story. Much ofthe work on the design of OSI was actually done by a group at Honeywell education Systems, headedby Mike Canepa, with Charlie Bachman as the principal technical member. This group was chartered,within Honeywell, with advanced product planning and with the design and development of prototypesystems.In the earlier and middle 70s, the interest of Canepas group was pr... ...mputer systemscommunicate with one another in the world wide web or in a corporate setting.Personally, I have found that the OSI model relates to just about everything that I have done as anIT consultant. During computer migrations and configuri ng desktops to be networked on the corporateland, enables the workstations to communicate via the OSI model and the TCP/IP model. Having tomap network drives enables substance abusers to have extra disk space other than just their hard drive to store data.When a user retrieves data from a network drive, the total process is through the seven layers of theOSI model. Configuring email accounts enables users to communicate via email transactions, a processthat uses the OSI model and the TCP/IP model.References1. Network Plus Guide to Networks (2002)2.
