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 any process in a higher place the take grade is called an Application in the transmission control protocol/IP architecture. In TCP/IP socket and port ar employ to narrow 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 ar deuce ravish Layer protocols. The Transmission Control Protocol (TCP) guarantees randomness transmission. The exploiter 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 pennon protocol in the TCP/IP Network Layer. al l last(predicate) upper and lower layer communications must travel through IP as they are passed through the TCP/IP protocol stack. In addition, there are many a(prenominal) supporting protocols in the Network Layer, such as ICMP, to stimulate 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 ingress layer. TCP/IP makes use of existing Data assort and Physical Layer standards rather than defining its own. Many RFCs imbibe how IP utilizes and interfaces with the existi ng data link protocols such as Ethernet, Tok! en Ring, FDDI, HSSI, and ATM. The physical layer, which defines the hardware communication properties, is not much 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 sealed 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 pauperisation to get a full essay, order it on our website: OrderEssay.net
