Suppose that a Web server runs in Host C on port 80. Suppose this Web server uses persistent connections, and is currently receiving requests from two different Hosts, A and B. Are all of the requests being sent through the same socket at Host C? If they are being passed through different sockets, do both of the sockets have port 80? Discuss and explain.

Suppose that a Web server runs in Host C on port 80. Suppose this Web server uses persistent connections, and is currently receiving requests from two different Hosts, A and B. Are all of the requests being sent through the same socket at Host C? If they are being passed through different sockets, do both of the sockets have port 80? Discuss and explain.
Let's pretend Host C is running a Web server on port 80. Suppose this Web server allows both Hosts A and B to make persistent connections. Is it possible that Host C is sending several requests over the same socket? Does port 80 exist in each of these connections if they are being sent through separate sockets? You should discuss and elaborate on this.
Let's pretend Host C is running an HTTP server on port 80. Consider that this Web server allows both Host A and Host B to establish persistent connections. Does Host C always send requests using the same socket? Does port 80 exist on both ends if they travel across separate sockets? You ought to discuss and elaborate on the matter.
Let's say that Host C is running a Web server that listens on port 80. Suppose that this web server is able to maintain persistent connections and responds to requests from both Host A and Host B. Is Host C sending all of the requests over the same connection, or are there many sockets in use? Do each of them have port 80 even though they are broadcast over separate sockets? It's something you need to discuss and provide some clarification on.
Assume Host C has a Web server on port 80. The Web server is receiving requests from two separate hosts, A and B. Are all queries forwarded to Host C using the same socket? Do both sockets have port 80 if they are passed through different sockets? How to explain?
consider 3 hosts (A , B and C) where A is running 3-TCP process, B has 1-TCP process and C is running 2-UDP process all process are trying to connect to a web server to download a file . How many new socket(s) will be created at the server side? Explain why?
Assume Host C runs a Web server on port 80. Assume that this Web server accepts requests from Hosts A and B and that persistent connections are enabled. Is Host C sending all of the requests through the same socket? Do they both have port 80 if they're broadcast via distinct sockets? It's something you ought to discuss and explain.
4. [Socket] What is a socket? Suppose a process in Host C has a UDP socket with port number6789. Suppose both Host A and Host B send a UDP segment to Host C with destination portnumber 6789. Will both segments be directed to the same socket at Host C? If so, how will theprocess at Host C know that these two segments originated from two different hosts? 5. [Demultiplex] Define multiplexing and demultiplexing. Briefly explain how TCP demultiplexing isdifferent than UDP demultiplexing. 6. [rdt] Consider a reliable data transfer protocol that uses only negative acknowledgments.Suppose the sender sends data only infrequently. Would a NAK-only protocol be preferable to aprotocol that uses ACKs? Why? Now suppose the sender has a lot of data to send and the end-to-end connection experiences few losses. In this second case, would a NAK-only protocol bepreferable to a protocol that uses ACKs? Why?
Suppose that a Web server runs in Host C on port 80 . Suppose also that this Web server uses persistent connections, and is currently receiving requests from two different Hosts, A and B. a) Are all of the requests being sent to the same port number at Host C? b) Will the client use port 80 in its local machine to communicate with the server? c) How does the server differentiate between the two requests?
QUESTION 19 Suppose a process in Host C has a UDP socket with port number 4320. Suppose both Host A and Host B each send a UDP segment to Host C with destination port number 4320. Then both of these segments will be directed to the same socket with port number 4320 at Host C True False QUESTION 20 With TCP’s flow control mechanism, where the receiver tells the sender how much free buffer space it has (and the sender always limits the amount of outstanding, unACKed, in-flight data to less than this amount), it is not possible for the sender to send more data than the receiver has room to buffer. True False
Assume Client A starts a Telnet connection with Server S. Client B starts a Telnet connection with Server S about the same time. If A and B are distinct hosts, is it conceivable that the source port number in the segments from A to S is the same as the source port number in the segments from B to S?
Let's say Host C is a Web server that listens on port 80. Assume that this web server allows persistent connections and that it accepts requests from hosts A and B. Is Host C using the same socket to transmit each request? If they're broadcast over different sockets, do they both have port 80? You should talk about it and provide an explanation.
