Solved in 3 steps
- Below is snw_transport.py. Make sure the code works properly and is plagarism free. Make sure to show the screenshot of the output with the screenshot of the code being tested as plagarism free. snw_transport.py import socket class UDPSender: def __init__(self, host, port): self.sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) self.receiver_address = (host, port) def send_file(self, file_path): pass UDP receiverclass UDPReceiver: def __init__(self, host, port): self.sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) self.sock.bind((host, port)) def receive_file(self, file_path): pass if __name__ == "__main__": passUsing 'import threading' and 'import socket' create a simple and functional Python chat application. Provide an example by creating a server.py and client.py class that allows two clients to connect to one server. Please create your own code and not copied from past questions. As someone whose still brand new to Python, include comments and screenshots. Try to have the code run in the command prompt. Server can allow the clients to input their own usernames. Once the server receives the message from a client, it will forward the message to the intended client and vice-versa. A client can disconnect from the server by sending “.exit” message anytime. Server upon receiving “.exit” message from the client, will close the connection with it.We limit ourselves to the hour by querying the interfaces consecutively, one by one. There is nothing to stop us from querying both interfaces at the same time, which will reduce their response time.We take advantage of Go's simultaneous playback capabilities across Go sub-units, goroutines and Channels. We will place each query in its own subunit and run it in parallel. We then combine the answers into one channel and then calculate averages when all queries are complete.
- Write a complete bash script that monitors who logs in and logs out of the current CSELinux machine (e.g., cse01, cse02, etc.) where the script is running. In particular, youwill check the status of who is logged in every 10 seconds and report each user ID thatlogs in or logs out during that time frame. Note that there may be more than one userthat logs in or out duringthis interval. You must include the host name when reportingthe user ID information. In addition, you will install a custom signal handler to trap the SIGINT(i.e.,^C) one time before you are able to terminate the script with the SIGINT. You will also print out the current date and time and report the number of users loggedin,even if there are no changes (i.e.,no one logged in or out during the interval). HOW TO DO THIS? PLEASE EXPLAIN WITH ANSWER!!An auction is being conducted for a valuable item of price Rs.10,000. There are three persons participating in the auction (three threads). Each person has only one chance to bid. If he tries to bid again, he has to wait until all the other threads are given a chance. Synchronize the events to organize the auction. Use random generator to quote the price of the item above 10,000. The thread with the highest price will win the valuable item.Create a java client class that will do the following:• Create a socket to connect to the server using port 8000• Initially show a welcome message (see Figure 5 below)• Prompt the user to enter product name, type and price• Send product details to server• Receive response from server to indicate whether product has been added to database or not• Allow user to add more products• Close the client when the user types “stop” for the product name and output a message“Exiting Checkers Stock Taking App, Good bye!"See Figure 5 attached which shows the operation:
- Exercise 1: Write a thread class TabPrinter that prints the elements of an array of integers (in one line) every 2 seconds 5 times. Use the way of extending the class thread. Write the main method which creates and starts three threads Printer which will print different arrays of integers. After that it prints "Main won’t wait. Main exits". Modify the above thread program so that you implement the interface Runnable. Make the main thread waiting till all other threads finish execution. ____________________________________________________________________________________________ Exercise 2: Write a thread class TextThread that prints a text every 1 second 10 times. Read the following main class. Try to guess what will be its output. class Test { public static void main(String s[]) throws Exception { TextThread x = new TextThread ("I am thread x"); TextThread y= new TextThread ("I am thread y"); System.out.println("I am Main thread"); } } Write it and execute it. Is the…Write a Java program that creates a new thread called PrintEven, that prints the Even numbers between 1 and N. N should be sent from the main thread to the PrintEven thread.write a Node/Express web server that supports routing via endpoint /cookie. Declare a variable named a and initialize it to 10 seconds.In the callback of route /cookie:Check to see if the browser sends a cookie named startIf cookie start received by the server, increment value in variable a by 2 seconds.Creates and sends a cookie that expires after the number of seconds specified in the variable a.The cookie is to be named startwith assigned value of 450.Import package cookie-parser for cookie handling
- Question 2 Consider this attempted implementation of the ReceiveCallback method from PS7: 1 private static void ReceiveCallback(IAsyncResult ar) { SocketState state = (SocketState)ar.AsyncState; Socket socket = state. TheSocket; try{ int bytesRead 4 = socket. EndReceive(ar); ... } catch (Exception e){ 5 6. } state.OnNetworkAction(state); state.TheSocket.BeginReceive(state.buffer, 0, SocketState.BufferSize, 0, ReceiveCallbac k, state); } Which line(s) do not belong in this method? Select all that apply. O 1 O 2 O 3 4 O 5 O 6Consider the following docker-compose file (docker-compose.yml) for launching the WordPress and MYSQL stack. version: '3.2 services: mysql-server: container name: mysql ports: - "13306:3306" environment: MYSQL ROOT PASSWORD: 12345 MYSQL DATABASE: Wordpress MYSQL USER: wordpressuser MYSQL PASSWORD: secret image: mysql/mysql-server wordpress: image: wordpress:latest container name: wordpress ports: - "20080:80" environment: WORDPRESS DB HOST: mysql-server:3306 WORDPRESS DB USER: wordpress user WORDPRESS DB PASSWORD: secret depends on: - mysql-serverCreate a simple Client-Server communication via Sockets where Client will send the message in following form → {message, SHA_256_hash_value}. Once the server receives the message it will parse it, calculate the SHA_256 hash value of the message part and compare it with the received hash. If values are matching it will send 'OK' back to Client, else 'Message was compromised'. Use Java GUI to send and receive messages in both parties (client and server).
