Subnetting a Class A Address: You will determine the information needed for a class A network that is being divided into six network segments. The network ID of the class A address is 120.0.0.0. Take a few pieces of paper and calculate the new subnet mask, the network ID, the first valid IP address, the last valid IP address, and the broadcast address of the four subnets. Once you have calculated your answers, fill in the following table. Refer to the subnetting example in this chapter as a guide to help you calculate the answers.

Transcribed Image Text 2. You are required to design IP addressing scheme for the Pantai Siring's branch for all floors using VLSM subnetting. You may use any private IP address class (10.0.0.0 to 10.255.255.255, 172.16.0.0 to 172.31.255.255 or 192.168.0.0 to 192.168.255.255). User group are as follows: a. Ground Floor- Administrator – 10 hosts b. 1* Floor - Lecturer – (Based on the last 2 digits of your Matric Number) For Example: B031910402 – 2 hosts only c. 2nd Floor - Student – 250 hosts d. 3rd Floor - Management – 80 hosts Explain in steps the calculations of your IP addressing scheme.
USING JAVA (Java Socket /TCP Programming) Create a chat/messaging application that has the following functionalities/features: Each user must log in to the system before he/she can perform actions/tasks. (passwords and usernames are stored in an XML file) Users must be allowed to send a broadcast message to all other users that are logged in. Any user must be allowed to send private messages to any of the established users.
Internet protocol version 4 ( IPV4 ) Represents each IP address as a 32-bit binary number. Internet protocol version 6 ( IPV6 ) represents each IP adress as a 128-bit binary number. WHich of the following best describes the result of using 128-bit addresses instead of 32-bit adresses- 4 times as many address are available- 96 times as many addresses are available - 2^4 times as many adresses are avialabe- 2^96 times as many adresses are available

USING JAVA (Java Socket /TCP Programming) Please make a program that will allow users to send private messages to other users (not the server). All the users have their usernames and passwords stored in an XML file Users can only send messages to online users Messages to offline users will be stored in a separate XML file
Both the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) are transport layer fundamental protocols. Please provide an explanation for why an application would be built to use TCP rather than UDP. Please submit two (2) further examples.
Delays. A user in Madagascar, connected to the internet via a 100 Mb/s (b=bits) connection retrieves a 250 KB (B=bytes) web page from a server in Tokyo, where the page references three images of 500 KB each. Assume that the one-way propagation delay is 82 ms and that the user’s access link is the bandwidth bottleneck for this connection. a.) Approximately how long does it take for the page (including images) to appear on the user’s screen, assuming non-persistent HTTP using a single connection at a time? (For this part, you should ignore queueing delay and transmission delays at other links in the network)b.) Assume a cache rate of 45% on the information received by the user in Madagascar from the Tokyo server. How does this affect your answer in a? Show your work.

Please answer and not copy answers from the internet cause i need some understading : An educational institution has an access network whose operating parameters are as follows:access link to originating servers’ rate: 15.4 MbpsRTT from institutional router to server: 2 secWeb object size: 100K bitsAverage request rate from browsers to origin servers: 150/sec average data rate to browsers: 45.0 MbpsInstitutional access network speed: 1Gbps. 3.1. You are requested to provide the performance of the institutional access network in terms of• LAN utilization• Access link utilization• End-to-end delay from the access network to the origin servers. Note: Assume that the requests from the web client to the originating web servers are of the order of 2GB of data on average. 3.2. Assuming that the institution would like to install a web cache in its access network with a cache hit rate is 0.65, you are asked to recompute the new performance of the access network…
Assume a client is connected to the server and has already received an HTML webpage. It reads the webpage, and it now needs to get 3 new files, File A is 5 MB file B is 1 MB and file C is 1 KB. The client requests the files in the order A B C. The link has an RTT (round trip time) of 0.5 seconds and a bandwidth of 8 Mb/s(Megabits per second) (or 1 Megabyte per second). The client can reuse the open connection if the protocol allows it to. For all parts of this problem ignore header sizes, and start the timer when the client sends How long does it take to get file C under HTTP 0? How long does it take to get file C under HTTP 1 (assume the browser does not support pipeling)? How long does it take to get file C under HTTP 2 assuming a frame size of 1 KB and no server push? What event would make HTTP 3 faster than HTTP 2 for this use case (ignore TLS)?
