In this problem, we will use a widely-used program, "ping". You may want to read about it if you are not already familiar with it (e. g., type "man ping" in google ).
a. Describe briefly the function of "ping".
b. Try using "ping" on your computer. Specifically, use 5 probes, each probe of 40 bytes, to obtain 5 samples of round-trip times from the machine you are using to a destination machine that you choose (e. g., www. cnn). List the command you use and the results you get.
c. Calculate the mean and the standard deviation of the round-trip times.

What makes myhexadecimalnumber a child of mynumber? which methods does myhexadecimalnumber inherit directly from the mynumber class? what can an instance of the mynumber class do? what can an instance of the myhexadecimalnumber class do? which methods are overridden? why are they overridden? how many examples of overloading are there? why was this done? where is the super keyword used? what is it doing? why isn’t the incoming value set immediately in the second myhexadecimalnumber constructor? how many examples can you find of an inherited method being called?
