- PROGRAM DESCRIPTION:In this assignment, you will write two complete C programs to support a client/server model using Linux sockets for a UDP “ping” utility, similar to the ping utility already available on our CSE machines. Servero The server program will be called with one command-line argument, the port number being used, such as ./minor4svr 8001. If the user calls the server program with too few or too many arguments, you will print out a usage statement and terminate the program.o The server will set up a UDP socket on the Internet (i.e., INET) domain and then wait in an infinite loop listening for incoming UDP packets, specifically PING messages from a client.o Packet LossUDP provides applications with an unreliable transport service. Messages may get lost in the network due to a variety of reasons. Since packet loss is rare or even non-existent in typical campus networks, the server in this lab will inject artificial loss to simulate the effects of network packet loss. The…Use Linux executable objectCode6 for this question. These files are on syccuxas01.pcc.edu in directory ~michael.trigoboff/cs201/quiz02LinuxFiles. Using gdb, figure out the value that will be in ST(0) just before main returns. Question options: 1) pi - 1 2) log(base2) 10 3) log(base 10) 2Problem 2. Rob has successfully installed Spark in Ubuntu. He also runs the WordCount example successfully. He now can start understanding each line in the WordCount.py file. He opens the pyspark shell. Suppose that the Spark context "sc" is already defined when he opens the shell. He wants to load the data "/home/rob/data/peterpan.txt". The command he uses is $ book = sc.textFile("/home/rob/data/peterpan.txt")
