This is an HTTP question please show work and explain accordingly (1 question, 4 parts)

In this assignment, you will develop a simple Web server in Python that is capable of 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 file preceded 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 should return a “404 Not Found” error message. Your job is to code the steps above, run your server, and then test your server by sending requests from browsers running on different hosts. If you run your server on a host that already has a Web server running on it, then you should use a different port than port 80 for your Web server. Make sure to test your…

Q10: Complete the frames (x & y) given below with appropriate port, IP and MAC addresses. The sender Host E has two applications running; one for email with port number 49254 and the other for accessing the web server with port number 52167. The frame x is intended for the BRACU Web server and frame y is coming from the Email Server.

Primitives of transport service assume asymmetry between the two end points during connection establishment, one end (server) executes LISTEN while the other end (client) executes CONNECT. However, in peer to peer applications such file sharing systems, e.g. BitTorrent, all end points are peers. There is no server or client functionality. How can transport service primitives may be used to build such peer to peer applications?

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.

Question 23 A client's browser sends an HTTP request to a website. The website responds with a handshake and sets up a TCP connection. The connection setup takes 2.1 ms, including the RTT. The browser then sends the request for the website's index file. The index file references 8 additional images, which are to be requested/downloaded by the client's browser. Assuming all other conditions are equal, how much longer would non-persistent HTTP take than persistent HTTP? (Give answer in milliseconds, without units, rounded to one decimal place. For an answer of 0.01005 seconds, you would enter "10.1" without the quotes.)
