1.)What argon the four grades of the transmission control protocol/IP model? screening Layer- The Application Layer in transmission control protocol/IP groups the functions of OSI Application, insertion Layer and Session Layer. Therefore all process in a higher place the enthrall layer is called an Application in the transmission control protocol/IP architecture. In TCP/IP socket and port ar employ to set the path over which applications communicate. Most application level protocols ar associated with one or more port number. station Layer- In TCP/IP architecture, there argon deuce capture Layer protocols. The Transmission Control Protocol (TCP) guarantees randomness transmission. The drug user Datagram Protocol (UDP) transports datagram swithout end-to-end reliability checking. Both protocols are utilitarian for different applications Network Layer- The Internet Protocol (IP) is the primary beam protocol in the TCP/IP Network Layer. every(prenominal) last(predicate) upper and lower layer communications must actuate through IP as they are passed through the TCP/IP protocol stack. In addition, there are numerous supporting protocols in the Network Layer, such as ICMP, to drive on and manage the routing process.

Network devil Layer- In the TCP/IP architecture, the Data plug into Layer and Physical Layer are normally grouped together to become the Network find layer. TCP/IP makes use of existing Data middleman and Physical Layer standards rather than defining its own. Many RFCs draw off how IP utilizes and interfaces with th e existing data link protocols such as Ether! net, Token Ring, FDDI, HSSI, and ATM. The physical layer, which defines the hardware communication properties, is not a great deal directly interfaced with the TCP/IP protocols in the network layer and above. 2.) Which layer of the TCP/IP model processes requests from hosts to make trustworthy a connection is made to the appropriate port? Answer- (Application layer) 3.) What are well-known ports? Answer- (A number from 0 through 1023 used to...If you want to get a full essay, order it on our website: OrderEssay.net
