- 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?A classless address is given as 177.200.180.92/27.

- Consider a web page whose base file is of size S1 = 10 KB. Assume that the web page consists of N = 20 inline objects each of size S2 = 100 KB. Assume that the round-trip time to the web server is T = 100 ms and the bottleneck capacity is C = 10 Mbps. Ignore any packetization delays and header overhead.a. Assuming non-persistent HTTP is used with a single TCP connection, how long does it take to download the web page?b. Assuming non-persistent HTTP is used with 4 parallel TCP connections, how long does it take to download the web page?c. Assuming pipelined, persistent HTTP is used, how long does it take to download the web page? ”Pipelined” means requests for multiple objects can be sent back-to-back on the same connection.d. Assuming non-pipelined, persistent HTTP with 2 parallel TCP connections is used, how long does it take to download the web page? Assume that the 2 parallel connections equally share the total available bandwidth C.Answer the following: a) Rewrite the given IPv4 address using dotted-decimal notation and find the class. 01011110 10110000 01110101 00010101 b) Rewrite the given IPv4 address in binary representation and find the class.Modify the following code to use only ONE message queue for one server and multiple clients Computer Science
