'Networking models Review Essay\r'

'3.1: Ne tworking models Review: The two networking models are transmission control protocol/IP which had 5 polar seams and the OSI model which has 7 layers. They mainly incorporate the like layers and the only difference is that the TCP/IP layer combines layers 5, 6 and 7 all into layer\r\n5. some(prenominal) models are along the same line of selective information and both explain how a network moves info. 3.2: OSI propagation model: The OSI model includes two more layers that the TCP/IP layer already had but is constructed in only layer 5. 7: ApplicationWeb browser,\r\n6: PresentationWhat is universe displayed on your page\r\n5: SessionControl structure amongst sessions\r\n4: Transport(TCP) Transfers data between points\r\n3: Network(IP underwrite/URL) Routing, responsible for addressing, s repealing and translation of logical and physiological addresses 2: selective information linkSends frames back and forth with necessary sync and error control (MAC/PPP)\r\n1: Physic al(Copper, wires ect) Defines the robotlike procedures that are infallible to establish and maintain physical links.\r\n3.3 The TCP/IP model\r\nTCP/IP reference model; includes all information as OSI but only has 5 layers and not 7, stage 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 soldiery communications\r\n4: Transport(TCP) transfers data between end points\r\n3: Network(IP/URL) The routing process, packet switching and exchanging (looking for your URL) 2: Data LinkSends frames to and from with flow control, error control and sync; likewise addresses topology and medias. 1: Physical(Copper, wires ect) Defines mechanical procedures that are required to establish and maintain physical links\r\n3.4 data link connections\r\n ready reckoner A is trying to ship information to Computer B, the IP address moldiness see the adv ertisement from Computer B for the router to sleep together 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(prenominal) ether and PPP to further send to Computer B.\r\n'
