- Question 11 mah.Of the following, which are host addresses, network addresses or broadcast addresses? 192.168.3.0/24; 192.168.3.0/23; 192.168.253.255/23; 192.168.253.255/22. Full explain this question and text typing work only We should answer our question within 2 hours takes more time then we will reduce Rating Dont ignore this line42. Though there are practical reasons why we don't complicate our lives this way in the real world, from a theoretical perspective we could borrow non-consecutive bits for subnetting. So, when borrowing the first host bit, the second host bit and the last two host bits (counting from the left of the host bit field) from 172.1.0.0 can you determine the following: a. subnet maskb. network address for 0th subnet, 1st subnet and 2nd subnet?c. total number of subnets and number of useable subnets?Answer the questions below about CSMA/CD protocol: i) Fill in the missing words in the gaps of the following text: “In CSMA/CD the ____________ (A) waits K ____________ (B) after a collision, where K is drawn ____________ (C). If you take the last three digits of your QMUL student ID as an example of value for K, the adapter would wait _________ (D) ____ __ (E) that corresponds to ___________ (F) miliseconds for a 5Mbps broadcast channel, ___________ (G) miliseconds for a 100Mbps broadcast channel, and ____________(H) miliseconds for a 1000 Mbps broadcast until returning to the step of sensing the channel.” Note: You are required to write down the gaps numbered A to H and show your calculations.
- Based on the given block data below, answer the following questions. Hint: First do Google search for ‘packet dump decode’. Then cut and paste the block of data below into the input data section. Then press decode. You will be able to find the answer from the decoding result. Hint Q6: For the payload of the application layer, look at the last few bytes in ASCII. You can use the ASCII character table to manually convert them. If you understanding the layer 4 destination port #, you understand what it is asking for. There is only one kind of information for the port #.

To transmit individual bits across a medium To transmit data between two directly connected network devices To transmit data between two hosts across a network of many interconnected devices To provide end-to-end services such as reliable delivery, flow control, and persistent connection To provide a service to the end user such as delivering a web page or transferring a file Suppose users share a 20 Mbps link. Also suppose each user transmits continuously at 2 Mbps when transmitting, but each user transmits only 30 percent of the time. If circuit switching is used, how many users can be supported? 5 10 2 20 What is the network address of the IP address 207.45.155.108/20? How many host addresses can you have in the following subnet 201.18.23.0/29? Assume that all addresses in this block can be used as a host address. How long does it take to send a 100MB file from host A to host B over a circuit-switched network?…Question 9 1) What is the data transmission time to send a 20 GiB file over a link with 1 Gbps line rate?

(Show your work) 2) How long will it take to upload a 15 GB file to a cloud server with an upload speed of 50 Mbps? You can assume there is no overhead. (Show your work)A file of size 325MB is downloaded via HTTP/SSL. What is the time it would take to download this file from a remote server assuming an ISP 512Kbps (down) dedicated download line with no other activity sharing bandwidth? In your discussion, identify two communication issues that would increase and/or decrease download time. How would the download speed be affected it was downloaded via FTP.Which of the OSI layers is responsible for each of the following: a. allows the tasks to be synchronised b. Error detection and correction. c. Allows for flow management. d. Separate data into packets.
- Please typed not hand written Exercise 1: We are sending a 7.4 KB (care this is kilo bytes!) file from a source host to a destination host. All links in the path between source and destination have a transmission rate of 8 Kbps. Assume that the propagation speed is 2 * 10^8 meters/sec, and the distance between source and destination is 40,000 km. Reply to the following questions. Question:Now suppose there are eight links between source and destination (7 routers in the path between source and destination). Each link is 5000 km long. Again suppose the file is sent as one packet. Suppose there is no congestion, so that the packet is transmitted onto the next link as soon as the router receives the entire packet. What is the end-to-end delay(transmission delay plus propagation delay)? Remember to add headers.4) Suppose you would like to urgently deliver 50 terabytes data fromBoston to Los Angeles. You have available a 100 Mbps dedicated link for datatransfer. Would you prefer to transmit the data via this link or instead use FedExover-night delivery? Explain. 5) Refer again to problem 4.a. How long does it take to send the file, assuming it is sent continuously?b. Suppose now the file is broken up into 20 packets with each packet containing40,000 bits. Suppose that each packet is acknowledged by the receiver and thetransmission time of an acknowledgment packet is negligible. Finally, assume thatthe sender cannot send a packet until the preceding one is acknowledged. Howlong does it take to send the file?Question #5 Access to media by multiple senders at the same time lead towards data collision, which particular protocol(s) and at what Layer(s) these are available to cater this issue? Does these protocols ensure 100% collision free delivery? If not then what other mechanism are available to resolve the issue? Elaborate with the help of diagrams, how different types of MAC Address (unicast, multicast and broadcast) works. Among the two popular LAN technologies, Ethernet and WiFi, which one has the higher data rate and highest bit error rate (also explain why)?
