Osi Model Essay -- Networks Telecommunications

UNDERSTANDING THE OSI MODEL AND THE kind WITH TCP/IPThe Open Systems Interconnection (OSI) deterrent example is a book of facts tool for understanding datacommunications between any dickens networked systems. It divides the communications processes intoseven layers. Each layer both performs specific functions to assist the layers above it and offersservices to the layers below it. The three lowest layers focus on passing traffic through and through the network toan end system. The top quaternity layers come into play in the end system to complete the process.This innovation impart 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 explain how the 802 specifications expanded the OSI reference bewilder by dividing thedata affiliation layer into two layers.Finally, this paper will draw comparisons between the theory-based OSI model and the functionalTCP/IP model. Although TCP/IP has been utilize for network communications before the adoption of theOSI model, it supports the same functions and features in a differently layered arrangement.The history 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 through by a group at Honeywell Information Systems, headedby Mike Canepa, with Charlie Bachman as the principal technical member. This group was chartered,within Honeywell, with advanced product think and with the design and development of prototypesystems.In the early and middle 70s, the relate of Canepas group was pr... ...mputer systemscommunicate with one another in the world considerable web or in a corporate setting.Personally, I deal found that the OSI model relates to just about everything that I have done as anIT consultant. During computer migrations and configuring 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 users to have extra criminal record 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.
