Osi Analogy Paper

OSI Model Analogy Trevor Crews Strayer University The OSI model is the model developed for computer-to-computer chat theory over a network. This model breaks down all the functions that occur into septenary distinct layers. These layers be, application, presentation, session, transport, network, data link, and the physical layer. Each one encompasses a position part of the process that occurs during the communication. In order to simplify this think of it the like sending a case through the post office.It can be broken down into seven stages or layers for this event. We start with bringing an item or letter to the post office that is to be sent to a determined destination. This is essentially what happens in the application layer. This is the interface among the communication and the entire process as it is in how a computer works. succeeding(prenominal) the item is package and put into a box or envelope. This is convertible to how the presentation layer functions. In thi s layer the communication is formatted, encrypted, and compressed fundamentally prepared for sending.Our package is then tagged with tracking schooling and tagging information that allows us to track it and verify if there are any new(prenominal) packages and if needed what order they go in. This is similar to the session layer. Next our package is put into a sorting device of some kind that sorts things base on size to see if it is able to be sent with another(prenominal) shipments or broken down to be sent different ship canal if it is to large. This is similar to the transport layer of the OSI model. The similarities go on over the bordering few layers as well.After packages are sorted they couriers inspect the packages and are condition the specific routes they are to take in order to deliver the specify packages to the correct recipients. This represents the network layer in that the connections are established between the computers and the routing is also established. Ne xt the packages are loaded onto the means of their transportation. This can implicate both truck and plane or whatever other mode is needed to en legitimate delivery. This is how the data link layer works. The information is packaged generally in frames and sent via the proper transmittal method via the designated route.The get-go of this process ends with the drivers getting into to their vehicles and driving towards the destinations with the packages. This is the physical layer in which the transmission takes place. After all this takes place it goes back through the same layers in the reverse order to ensure that everything that has happened was in the correct order and method. For example a package arrives at its destination, its then unloaded, inspected to make sure its intact and not damaged, signed for to verify the correct address and recipient, unpacked, and eventually read.While the process as a whole can be overpoweringly complex if it is broken down into layers as the OSI model does it can be viewed a little more simplistically and compared to modern day processes. Such as the post office as I have described. There are also many other similarities that if one looked they could make connections to. Works Cited Dean, T. (2010).
