Which of the following is a correctly phrased statement for how to use OSI terminology? a. HTTP is a Layer 5 protocol. b. IP is a network layer protocol. c. TCP is a Layer 2 protocol. d. Leased lines are Layer 7 standards. 10. Which of the following statements is true when comparing the OSI and the TCP/IP model as defined in RFC 1122? a. Two layer names match. b. The lower four layers of TCP/IP define the same kinds of functions as the matching layer numbers from OSI. c. The TCP/IP five-layer model is old and has been replaced by the seven-layer OSI model. d. The TCP/IP application layer defines functions that match closely to only two OSI layers (application and presentation). 12. A TCP/IP network includes an Ethernet LAN with 10 PCs uses a LAN switch. PC1 sends data intended for an app running on PC2. Which of the following mechanisms does Ethernet define so that PC2 receives and processes the …show more content…
Ethernet defines MAC addresses, but when used in a TCP/IP network, it does not use the addresses, instead relying on IP addresses. c. Ethernet works as a broadcast network, with no data-link addresses, so all devices (including PC2) receive the data. d. PC1 cannot send data directly to PC2 in this network. 14. Which of the following are true facts about IP addresses? (Choose two answers.) a. 48 bits in length b. Can be written in DDN format c. Are listed in the data-link trailer d. Used by routers to make a forwarding decision 16. Which of the following statements is true comparing LANs and WANs? (Choose two answers.) a. LANs generally connect devices that are nearer to each other, compared to WANs. b. WANs are purchased, and LANs are leased. c. WANs generally connect devices that are nearer to each other, compared to LANs. d. LANs are purchased, and WANs are leased. 18. Which of the following answers list true facts about the network layer of TCP/IP? (Choose two answers.) a. It focuses mostly on the network between endpoints, rather than the endpoints. b.

    In this section the fast-recovery algorithm that makes TCP NewReno[1] perform better than the Reno[3], is described. During congestion avoidance if the sender receives triple duplicate ACKs, then it performs fast-retransmission and enters into fast-recovery. In fast-retransmit the sender retransmits the lost segment,sets the threshold value for slow-start as ssthresh = cwnd/2, and sets congestion window, cwnd = ssthresh+3 segments. In fast-recovery, the sender increases its congestion window by one segment for each subsequent duplicate ACK received that indicates a segment is reaching the destination. It can transmit new segments if permitted by its congestion window.…

    E. Also suppose a malicious node M can hear A, B, C and D. The attack can be described as follows:[18] “To start the attack, M changes its MAC address to match A’s, moves closer to and out of the range of A. It then sends an RREP to B that contains a hop count to X that is less than the one sent by C, e.g., zero. Therefore B changes its route to the destination, X, to go through A, as illustrated in Figure. 1.4.…

    WANs cover larger areas, such as cities, and even allow computers in different nations to connect. LANs are typically faster and more secure than WANs, but WANs enable more widespread connectivity. And while LANs tend to be owned, controlled and managed in-house by the organization where they are deployed, WANs typically require two or more of their constituent LANs to be connected over the public Internet or via a private connection established by a third-party telecommunications…

    TCP/IP Transmission control Protocol/Internet protocol used to connect host computers on internet. First internet ARPANET was developed when US Department of research projects agency (ARPA) in the end of 1970s needed a system to share the resources of their big mainframe systems. In start ARPANET used Network Control Protocol but in 1974 TCP protocol was introduced and all pervious protocols were replaced with TCP Protocol. TCP/IP was the leader in protocols used as a communication protocol on the internet. TCP/IP is still being used as a communication protocol in network operating systems (Abbate, 1994).…

    Queuing schemes provide predictable network service by providing dedicated bandwidth, controlled jitter and latency, and improved packet loss characteristics. The basic idea is to pre-allocate resources (processor and buffer space) for sensitive data. Each of the following schemes require customized configuration of output interface queues [8]. • First In First Out (FIFO): the simplest form, which also known as first-come, first-served (FCFS) queuing, involves buffering and forwarding of packets in the order of arrival.…

    Algorithm: Exponential Growth Of The Internet And The World Wide Web

    The Internet was originally called the ARPANET, and in order to enhance the ARPANET to be enable may different types of computer networks to all communicate with each other, an open source protocol needed to be created, hence the development of TCP/IP. TCP/IP improved communications throughout the network and allowed all computers to easily communicate with one another. Another technology that helped expand the ARPANET to more users in a specific location was the development of the Ethernet. Ethernet is a coaxial cable that is still used today in many local area networks. Ethernet is highly effective in moving data from one computer to another at high speeds.…

    Most networks today use the TCP/IP protocol for how to communicate on the network and the most common is IP Version 4. Missing Elements In the diagram, it is showing that each department has three IP addresses assigned as well as three printers which are connected to the network via Ethernet. we can see that each department has three IP addresses assigned to it, and there are three printers, one for each department. These computers can communicate with one another as well as the printers, server, and Internet.…
