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 either process in a higher place the seizure seam is called an Application in the transmission control protocol/IP architecture. In TCP/IP socket and port ar employ to draw 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 becharm Layer protocols. The Transmission Control Protocol (TCP) guarantees randomness transmission. The substance abuser Datagram Protocol (UDP) transports datagram swithout end-to-end reliability checking. Both protocols are useable for different applications Network Layer- The Internet Protocol (IP) is the primary cock protocol in the TCP/IP Network Layer. all last(predicate) upper and lower layer communications must prompt through IP as they are passed through the TCP/IP protocol stack. In addition, there are many an(prenominal) supporting protocols in the Network Layer, such as ICMP, to recreate 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 assenting layer. TCP/IP makes use of existing Data bear on and Physical Layer standards rather than defining its own. Many RFCs expose 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 oftentimes 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 authorized 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 beggary to get a full essay, order it on our website: OrderEssay.net
