- C++ how do I write code for this question: In computer networking, a socket is an application endpoint for communications services. Sockets consist of an Internet Protocol (IP) address, which is the logical address, and a port number, which points to a specific service at that address. Declare a struct called Socket that has a string field for an IP address and an int field for a port number. Then using the struct declaration above, show how you could establish a new service of type Socket called HTTP. This service runs on port 80 at IP address 192.168.0.15.socket programming in c++ In this project, students are required to implement a multi-threaded chat room service. The system will have one (multi-threaded) chat server, and multiple chat clients. Socket interface is used to implement network communications. The C/C++ chat application you are going to build is a console application that is launched from the command line using TCP connection. There can be multiple clients connect to a server and they can chat to each other. Only two users who are messaging can see each other’s message and other users cannot see these messages. It is a private chat between two users. The application consists of two parts: Server and Client. Each part can run independently on separate computers. Server manages the chat session. It maintains a list of the active clients and forwards incoming messages. The Server is multithreaded - communication with each client is through a separate thread. When Server is started, it starts to wait for client connections.…Socket programming c++ In this project, students are required to implement a multi-threaded chat room service.

- IN C language Write a socket server/client program such that The client sends to the server 2 integer numbers L and S and the server finds the difference between them and send the result of the subtraction (L-S) back to the client to display it in the terminal window.Topic: Data Communication & Network Write a socket server program named "RockPaperScissorsServer", which communicates with players (clients). Server firstly receives a name for the player. Let’s assume 1 is Rock, 2 is Paper and 3 is Scissors. Next Server receives any of the 3 number from the user, generate a random number between 1 to 3 itself and then apply the Rock Paper Scissors game logic (which is paper beats rock, rock beats scissors, scissors beats paper), Then it will tell the player if the player or server has won. Write another client program to communicate with the server. Kindly make the server in such a way the any time any player can leave and another player can join. Use Java to write the code. *** Reference code: Creating a simple Server *** import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.io.PrintWriter; import java.net.ServerSocket; import java.net.Socket;import java.util.Scanner; public class Server1 {…Create a java socket program which has the following functionality: Server: The server contains the IDs of multiple students (minimum 6). It accepts two types of operations from the client. The first one is a search operation, where the client provides an ID to the server. If the ID is found in the server’s list, the server returns found, otherwise the server returns not-found. The second one is an add operation, where the client provides an ID to the server, and the server adds that ID to its ID list. Note: The ID list can be an array / ArrayList or you can even use files. Client: The client sends 2 types of requests. The first one is for searching a student, where the client sends the student ID. If the data is found in the server, the server sends back found. Otherwise, the server sends not-found. The client shows the data sent by the server. The second type of request is adding a new student to the server. The client sends id of the new student to the server and the server adds…
- 2 Project Specification In this project, you are required to do socket programming in C language (Linux environment) to implement a pair of client and server that can achieve simple password verification to indicate the current market value of the stock. Your client will send a pair of username and password to your server and your server will verify whether the pair of username and password is legitimate or not for retrieving the stock value. Assume the only legitimate pairs of usernames and passwords that will be accepted by your server are as follows.

The contest consists of answering the maximum quantity of sums in 30 seconds. This is done in a concurrent way, which means, that there are three participants answering at the same time. The participant with most correct answers WINS. The jury is responsible in starting up the server, after that they wait for the clients. When the three clients are connected, they must send the message: READY to the server. When the server receives the three READY from the clients, the contest starts. At the end of the program, the server must show the results .Execution (SERVER) - Please provide me the complete code and solution to arrive to the results below.python3 MathinikServer 192.168.1.2 Connected192.168.1.2 is Anne192.168.1.4 Connected192.168.1.4 is Billy192.168.1.3 Connected192.168.1.3 is MarkMark is READYAnne is READYBilly is READYStarting Contest…Contest…write a client-server program in C: Copy the program, compile and run(to ensure it is functional).

- Write a client-server java application in which two clients can send a Morse-code message to each other through a multithreaded server application. The client application should allow the user to type English-language when the user sends the message, the client application encoded the text into Morse-code and sends the coded message through the server to the client. use one blank between each Morse-code letter and three blanks between each Morse-coded word. Note: At the server side, use Map<String, Character> for the mapping between the Morse code and its corresponding normal character in javaUsing client-server socket programming, implement a multi-threaded server that returns to the client the synonym of a word as stored in a dictionary. The client should prompt the user for a word, reads the word from the screen and sends it to the server and waits for response from the server. Once the client gets the synonym of the word, it should print the word and its synonym on the screen and prompt for another word. This should continue until the user enters the characters @ to quit. Example: >>> python TCPClient.py Input a word: weak weak ==> frail Input a word: fair fair ==> just Input a word: @ Notes: 1) A file that contains some words and their synonyms is provided 2) In the server code, read the file to a global python dictionary object engDict = {} # empty dictionary object with open('dictionary.txt') as f: # open the file for line in f: tok = line.split() engDict[tok[0]] = tok[1] print(engDict) 3) Here is a Skelton of the server [some code here ] class…Using client-server socket programming, implement a multi-threaded server that returns to the client the synonym of a word as stored in a dictionary.
