The Python code used to create a single welcoming socket in the server is shown in the figure (the welcoming socket itself is not shown graphically); code is also shown for the client sockets as well. The three sockets shown in server were created as a result of the server accepting connection requests on this welcoming socket from the two clients (one connection from the client on the left, and two connections from the client on the right). mySocket = socket (AF_INET, SOCK_STREAM) mySocket.bind (myaddr, 6189 ); P1 Answer mySocket = socket (AF_INET, SOCK_STREAM) mySocket.bind (myaddr, 5854 ); ♫ transport QUESTION 1 OF 8 network link physical What is the source port # for packet C? www B source port: ? dest port: ?

- java programming language Write a simple program that demonstrates the concept of (Multithreads) using more than one channel in the same class. So that the failure of one channel does not affect the otherA messaging system reads message as 4-digit positive integer d1d2d3d4 and stores encoding of the message e1e2e3e4 for security reason. The encoding process is as follows: ei = (di+i) mod 3 For example, if message is 4590, the encoded message is 2101. Read any arbitrary message and display the encoded message in the following format: Original message = Encoded message = language : CWhat is encapsulation and de-encapsulation? How is it used in a network?
- Q2- You are designing a connection mechanism between two programs, sending packets of data over the internet. You are trying to choose a size for the packets to be sent, depending on the capacity of the channel (channel bandwidth). For example, if a channel has a capacity of 10KB, then you can choose a packet size of 10KB, and send one packet, or choose a packet size of 5KB and send two packets...Etc. The problem you face is that the two programs are at two different locations, with two different channel capacities. If the first channel had a capacity of 3201KB, and the second channel had a capacity of 4565KB, find the maximum packet size that is suitable for both channels.Vehicular traffic networks Recall that latency is the time it takes to get from one place to another (measured in seconds, minutes, or hours), and bandwidth is the amount of something that can pass through a point in a given amount of time (measured in cars per minute, bits per second, etc.). Consider this road network with six cities. Single lines represent 1 lane in each direction, and double lines represent 2 lanes in each direction. 6 mi 3 mi 3 mi 9 mi A В 5 mi 5 mi 8 mi E F 1. There are four different routes to get from A to B (without going in circles). What are the four routes? (In graph theory language, you would say there are four distinct paths that go from A to B without cycles.) 2. What is the total length of the shortest route? 3. Assume all the roads have speed limit 30 miles per hour. a. What is the latency of a car traveling from A to B along route ACDB? b. What is the latency of a car traveling from A to B along route AEDB? 4. Assume everyone follows the 2-second rule…I know this is "broad" for computer science, as this concept is networking based. So, I'm a cybersecurity student, I am good at pretty much everything else but networking in respect to the field (for a beginner obviously) My question is as follows: Basically, I've been given a network with 100 hosts, 50 hosts, and 20 hosts.I've been given an IP address of 172.34.100.0 /17Basically, I've been told to plan out this VLSM and subnet this network, but I have no idea where to start. Can you help me out? Let me know if you require more info, I'd be happy to lend it.
- Abstract: the main purpose of this experiment is build real time system using PPI 8255 to control devices connected to. Problem description: assume that there are two devices are connected to port A and two sensors are connected to port B of PPI 8255. They work according to the following table Sensors (S1S2) Devices (DID2) 00 01 01 10 10 11 11 00 Write a program to control these two devices according to the values of sensors.Write a program to calculate Routing table by using Dijkstra’s Algorithm. Your program should Ask user to enter the number of nodes and the weights of edges connected between nodes. Ask user to enter the starting node and calculate the routing table for that node. Output should be clear format and Use Java language to develop codePart A: Develop a TCP server program in java that waits for clients to connect. The server responds to the client with one of the following based on client’s request: Export public key generated using KeyPairGenerator Export Message Digest Export Digital Signature Send original text for the encrypted text received from client Part B: Develop a TCP client program that request from TCP server developed (in Part A) public key, Message Digest, Digital Signature and original text by sending the encrypted text. TCP client will display the various objects received from TCP server on its console.
