- Servers can be designed to limit the number of open connections. For example, a server may wish to have only N socket connections at any point in time. As soon as N connections are made, the server will not accept another incoming connection until an existing connection is released. Please write pseudo code to implement the synchronization using semaphore.You are tasked with the development of an E-Scooter ride-sharesystem. It allows registered commuters to approach an idle E-Scooter andreserve it, following which they use the E-Scooter to commute a certaindistance (that is not known prior to use). Finally, after the commuter reachestheir destination, they end the ride, which prompts an automaticcomputation of the ride fees. which is automatically debited using thecommuters registered payment details.Write an application in java that encrypts and decrypts on Counter mode using: Aphine chiper modulo 256, Hills chiper modulo 256 and S-DES (Simplifies DES). Testing data for S-DES using Counter mode start from: 0000 0000, with text in binary form: 0000 0001 0000 0010 0000 0100 and key: 01111 11101 which will give the result: 0011 1000 0100 1111 0011 0010. Decryption should work.
- Implement a Socket based Remote C compiler. NEED THE PROGRAM IN JAVA. The JAVA program will take a C program (from a txt file) as input, send it to the server to compile & execute it, and return it to the client. In other words,The client will write or chose a C program which will be copied to the server, compiled and executed in the server machine and return the result back to the client.Discuss the similarities and dissimilarities of creating server program using sockets as against RMI in JavaUsing Java sockets, implement the Remote Procedure Call (RPC). Consider the following requirements: 1. RPC contains multiple clients(with stubs), one Binder, multiple servers (with stubs). 2. Apply the RPC on any function with your choice.
- write a client-server program in C: Copy the program, compile and run(to ensure it is functional). Hint: IP address 0.0.0.0 and 127.0.0.1 (Loopback IP address); Insert appropriate comments in your example program to highlight the following aspects of the API: Creating a socket Endpoint addresses (IP + Port number) used Client connecting to server Server accepting to connect to client Client communicating with (sending request to) server Server accepting client request Server processing client request Server communicating with (sending reply back to) client Client receiving server’s response Client closing the connection Server closing a connection.Currently, the web server handles only one HTTP request at a time. Implement a multithreaded server that is capable of serving multiple requests simultaneously. Using threading, first create a main thread in which your modified server listens for clients at a fixed port. When it receives a TCP connection request from a client, it will set up the TCP connection through another port and services the client request in a separate thread. There will be a separate TCP connection in a separate thread for each request/response pair.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. 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…
