- Access Control List (ACL) and Capability Lists are the most common implementations for controlling access to objects in a system. Which of the two methods are used in UNIX/Linux file systems? What simplifications have been made to make the implementation more efficient?Define application binary interface.Sockets are low-level networking interfaces between computers. Many programming languages come standard with socket libraries for creating socket connections. In this lab, we’ll study the usage of networking sockets in Python to write a custom client/server program. Client/Server source code as a ZIP or RAR file in D2L Word document outlining the description of your program. The word document should contain screenshots containing your name on the VM and reports of what’s occurring in them. Demonstrate your socket solution accomplishes the following: The client connects to the server Client and server successfully exchange messages Following the TCP stream in Wireshark Identifying the message sent in Wireshark Any additional functionality you created in your solution. please use python.
- Operating Systems: Using C++ and data structures, with stacks, trees, graphs, linked list, classes as see fit, write a program: A simulation of process synchronization. Provide source code and a description of the simulations and how it seeks to demonstrate the chosen OS principle. You must submit screenshots within your documentation in this section of your running code to enhance your understanding.Parallel & Distributed Computing :- Parallel programming using multithreading with different variants in c/c++ ,openmp Please attach the screenshots of the code and result .What are the potential challenges or issues that can arise when serializing objects in a multi-threaded environment?
- . Explain the differences between stream socket and datagram socket with diagram. javaComputer Science Assume you are part of a project to develop a novel customized online standalone chatting application for a company. The chat is supposed to support text, audio, video messages; it is also intended to support video and audio streaming. Your role in the project is to coordinate the networking team (efficient data transmission). Other teams handle other parts, such as interface and video capture. Your team's target is also to create your own proprietary library, not relying on other proprietary or open libraries, except the socket API. (i) Describe the structure of your application in general. Will it be a client-server or P2P application? How do clients find the server or each other? Do clients need to connect to the server or each other? (ii) What type(s) of sockets do you need to use in your application? Justify your answer and give example(s). (iii) Do chat media require reliable, in-order packet transfers? If yes, which types of media from the description need it?…C # Text to Morse Code Converter- I need help getting the morse code to display in the morseCodeList using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Diagnostics;using System.Drawing;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Windows.Forms; namespace Morse_Code_Chapter__8//Create a struce for Morse Code { [DebuggerDisplay("{" + nameof(GetDebuggerDisplay) + "(),nq}")] public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void converterButton_Click(object sender, EventArgs e) {// key type = A and value type = .- Dictionary<char, string> letters = new Dictionary<char, string>(); letters.Add('A', ".-"); letters.Add('B', "-..."); letters.Add('C', "-.-."); letters.Add('D', "-.."); letters.Add('E', "."); letters.Add('F',…
- In an executable object file that is in executable and linkable format (ELF), which section defines the addresses of the stack and the heap? A. The data section B. The .text section C. These addresses are not defined in the executable object file. Instead, they are assigned by the operating system when the program is loaded in to me D. These addresses are not defined in the executable object file. Instead, they are assigned by the user when the program is running in memory. Reset Selectionn this assignment, you will develop a simple Web server in Python that is capableof processing only one request. Specifically, your Web server will(i) Create a connection socket when contacted by a client (browser)(ii) Receive the HTTP request from this connection(iii) Parse the request to determine the specific file being requested(iv) Get the requested file from the server’s file system(v) Create an HTTP response message consisting of the requested filepreceded by header lines(vi) Send the response over the TCP connection to the requesting browser.If a browser requests a file that is not present in your server, your server shouldreturn a “404 Not Found” error message.Your job is to code the steps above, run your server, and then test your server bysending requests from browsers running on different hosts. If you run your serveron a host that already has a Web server running on it, then you should use a differentport than port 80 for your Web server. Make sure to test your program…Title This assignment requires you to develop two Python programs. One is a client, the other is the... Description This assignment requires you to develop two Python programs. One is a client, the other is the server.</o:p> Server</o:p> The server should “register” x procedures that the client will be able to call. It will then bind to the address “localhost” and port 8000. This is the address and port that the server will listen to for requests. Note that if you have binding errors, you may use another port as your computer may have an application that is using 8000. Most of the time, however, this will work. Your server invocation must be in the following form:</o:p> python server.py localhost 8000These procedures to be supported are as follows:</o:p> name – returns the name of the server which is passed on the commandline during server invocation</o:p> help – returns a list of procedures that the server supports</o:p> servertime –…
