Networking models Review Essay

3.1 Networking moldings Review The two networking models are transmission control protocol/IP which had 5 different layers and the OSI model which has 7 layers. They mainly incorporate the same layers and the only difference is that the TCP/IP layer combines layers 5, 6 and 7 all into layer5. Both models are along the same line of development and both explain how a network moves data. 3.2 OSI reference model The OSI model includes two more layers that the TCP/IP layer already had solely is constructed in only layer 5. 7 ApplicationWeb browser,6 PresentationWhat is being displayed on your page5 SessionControl structure between sessions4 Transport(TCP) Transfers data between points3 Network(IP address/URL) Routing, creditworthy for addressing, billing and translation of logical and physical addresses 2 Data linkSends frames back and forth with necessary correct and error control (MAC/PPP)1 Physical(Copper, wires ect) Defines the mechanical procedures that are required to order and maintain physical links.3.3 The TCP/IP modelTCP/IP reference model includes all information as OSI but only has 5 layers and not 7, Layer 5 includes layers 5, 6 and 7 combines. 5 ApplicationCombines layers 5, 6 and 7 provides network services such as email, file transfers, exchanges of data, support connections between sessions and inner host communications4 Transport(TCP) transfers data between end points3 Network(IP/URL) The routing process, packet switching and exchanging (looking for your URL) 2 Data LinkSends frames to and from with immix control, error control and sync also addresses topology and medias. 1 Physical(Copper, wires ect) Defines mechanical procedures that are required to establish and maintain physical links3.4 data link connectionsComputer A is trying to send information to Computer B, the IP address must see the advertisement from Computer B for the router to know where to send the information. The router then strips the Ethernet and sends the information over a leased line to router B, Router B then sends connects to another ether and PPP to further send to Computer B.
