Network Protocols

A network protocol is a set of rules that govern how data is exchanged between the devices in a network. Network protocols enable communication between devices that are located in different parts of the world. Consequently, they are critical in today's digital communications.

2.2.10 Browser Caching (1). Consider the following scenario, in which a Web browser (lower) connects to a web server (above). There is no web cache in this question (so make sure you understand the difference between a browser cache and a web cache). Assume that the total Round Trip Time (RTT) propagation an
queueing delay between the browser and web server is 200 msec.
HTTP server
HTTP browser
with browser cache
Suppose that the browser makes an HTTP request to the server for an HTTP object, that the browser has a copy of that object in its cache, but that copy may or may not be up-to-date in its cache (and so the browser requests the object using the HTTP If-Modified-Since header field). Assume that the time taken to
transmit an HTTP reply (by the sender into the TCP connection) that contains a requested object in the body of an HTTP reply is 50 msec, but that the time taken to transmit a HTTP reply with a "304 Not Modified" reply code without an included object is negligible (e.g., zero). You can assume that a TCP connection ha
already been set up, so do not include that delay in your answer below.
What is the time from when the browser issues the initial HTTP GET request until it is able to display the requested object in the case that the browser does not have the requested object in its browser cache?

Can anyone help me with basic client-server interaction using TCP sockets in network programming in c code that includes csapp.c and csapp.h. and a text file of the student record that include first name, last name, age, major, and graducation year. The ideas is have 4 choice: Add record, Search Age Range, Search graducation year, and Terminate. In opition 1, it should collect all the data to the text file, in opition 2, it should search for age range from the text file. in opition 3, it should search the graducation year from the text file and if the year is not there it should print record not found. And opition 4, the client should close the connection and terminate. studentRecord.txt: John,Doe,24,Computer Science,2023Jane,Doe,22,Mechanical Engineering,2020Charles,Babbage,21,Math,2022George,Bool,25,Math,2023Marie,Curie,26,Chemistry,2023 I know this isn't enough but I want to understand about the client-server interaction using socket interface.

I made a TCP server using socket python,basically my server can: - Upload (“put”) request: The client should, at the very least, open (in binary mode) the local file defined on the command line, read its data, send it to the server through the socket, and finally close the connection. - Download (“get”) request: The client should, at the very least, create the local file defined on the command line (in exclusive binary mode), read the data sent by the server, store it in the file, and finally close the connection. To avoid accidents, the client should deny overwriting existing files. - Listing (“list”) request: the client should, at the very least, send an appropriate request message, receive the listing from the server, print it on the screen one file per line, and finally close the connection. I want you to draw an ER diagram that can show the process above please.
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.)

I am using SwaggerHub for API documentation for my web application. When I use the bearer token for authentication, and I run a get request that is supposed to return a JSON of the user's trip information. It returns a 200 HTTP response, but the body response does not return the JSON information, instead it returns HTML text. The image below shows the result. Why is this happening?
Suppose an HTTP client makes a first GET request to the gaia.cs.umass.edu web server for a base page that it has never before requested, which contains an embedded object, which causes the client to make a second GET request. A very short time later, the client then makes a third GET request - for the same base page, with that third GET request having an If-Modified-Since field (as does the 4th GET request that the client makes for the embedded object). Neither the base object nor the jpeg object has changed. How many round trip times (RTTs) are needed from when the client first makes the third GET request (i.e., when it requests the base object for the second time) to when the base page and the jpeg file are displayed a second time, assuming that: any time needed by the server to transmit the base file, or the jpeg file into the server's link is (each) equal to 1/2 RTT the time needed to transmit an HTTP GET into the client's link is zero? the time needed by the server to transmit…
