1.)What argon the four grades of the transmission control protocol/IP model?
screening Layer-
The Application Layer in TCP/IP groups the functions of OSI Application, insertion Layer and Session Layer. Therefore any process in a higher place the transport layer is called an Application in the TCP/IP architecture. In TCP/IP socket and port ar employ to delimitate 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 are deuce Transport Layer protocols. The Transmission Control Protocol (TCP) guarantees randomness transmission. The User Datagram Protocol (UDP) transports datagram swithout end-to-end reliability checking. Both protocols are useful for different applications
Network Layer-
The Internet Protocol (IP) is the primary quill protocol in the TCP/IP Network Layer. every 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 supporting protocols in the Network Layer, such as ICMP, to speed 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 Access layer. TCP/IP makes use of existing Data Link and Physical Layer standards rather than defining its own. Many RFCs describe how IP utilizes and interfaces with the existing data link protocols such as Ethernet, Token Ring, FDDI, HSSI, and ATM. The physical layer, which defines the hardware communication properties, is not ofttimes 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 certain 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 pauperism to get a full essay, order it on our website: Ordercustompaper.com
