- What does port mirroring provide?In the past, we mentioned that each JVM thread is only permitted to have a single active process at any one time. What makes you think that this is the case for you specifically?Language : C / C++ / Python Develop a simple Web server (parity generator) that is capable of processing the request from client. Create a socket connection, when contacted by the client the server has to process the request and give back the result. Client part The client has to send the data in bits (e.g 1100011000). It also has to send the number of frames it has to separate the data (e.g. 2 frames) Server part Server has to split the data into 2 parts (Frame 1 -> 11000; Frame 2 ->11000) and send back to the client. For each part server has to find the even parity and send

Argue either for or against the following proposi- tion: The TCP library should be redesigned to combine the four TCP server setup calls into just one or two new calls. If for, give the parameters and return values of the resultant new call(s), and give a description and example of its use. If against, give examples of things one might like to do that would be hindered by a consolidated system.
- Computer Science Networks and should be done in C language. Create a UDP client and server program that not only is able to locally transfer files but it gives the client the ability to send multiple copies of the file to multiple servers. Once the server program is initiated, it waits until it receives client packets. It then reads and saves the payload of the packets. The client reads a file from the disk and sends it to each server over a UDP socket by breaking the file up into mtu-byte sized packets. Client needs to be concurrent in sending the packets to all of the servers using threadsIn the past, we mentioned that each JVM thread is only permitted to have a single active process at any one time. Why do you believe this to be the case, and what factors contribute to your belief?1 IntroductionThe objective of this project is to learn TCP client-server interaction using a socket interface in C programming language. After completing this Project, you will have a basic understanding of the steps required todevelop a networking application. 2 Project SpecificationIn this project, you are required to do socket programming in C language (Linux environment) to implementa pair of client and server that can achieve simple password verification to indicate the current market valueof the stock. Your client will send a pair of username and password to your server and your server willverify whether the pair of username and password is legitimate or not for retrieving the stock value. Assumethe only legitimate pairs of usernames and passwords that will be accepted by your server are as follows.

- A Communications is a small phone repair shop. The owner, Ahmet, is currently working alone. Ahmet files his repairs on a customer basis and keeps them in a cupboard. Ahmet knows that he needs to switch to an information system because he wants to expand his business. When the customer brings a phone that needs repair, Ahmet detects the problem, records them in the file and gives the customer time and price information. At the beginning of each day, Ahmet checks the repair list, selects and completes the tasks that need to be done that day. When he sees that there is no required part in stock during the repair, he orders the part to the supplier and postpones that repair work to a future date, informing the customer. When the customer comes to pick up the phone that has been repaired, Ahmet issues an invoice and takes the payment from the customer. Once a week, Ahmet checks the stock and orders the decreasing products to the supplier. In order to develop the information system that…Instead of focusing just on speed, you should explain why deep access is better than shallow access from the programmer's perspective.Computer Networking Assignment 2 Lab 2: Web Server Lab In this lab, you will learn the basics of socket programming for TCP connections in Python: how to create a socket, bind it to a specific address and port, and send and receive a HTTP packet. You will also learn some basics of HTTP header format. You will develop a web server that handles one HTTP request at a time. Your web server should accept and parse the HTTP request, get the requested file from the server’s file system, create an HTTP response message consisting of the requested file preceded by header lines, and send the response directly to the client. If the requested file is not present in the server, the server should send an HTTP “404 Not Found” message back to the client. Code Below you will find the skeleton code for the Web server. You are to complete the skeleton code. The places where you need to fill in code are marked with #Fill in start and #Fill in end. Each place may require one or more lines of code.…
