In this mini programing project, you will gain a better understanding of Internet Control Message

Protocol $($ICMP$).$ You will learn to implement a Ping application using ICMP request and reply messages.

Ping is a computer network application used to test whether a particular host is reachable across an IP

network. It is also used to self$-$test the network interface card of the computer or as a latency test. It works

by sending ICMP $$echo reply$$ packets to the target host and listening for ICMP $$echo reply$$ replies. The

"echo reply" is sometimes called a pong. Ping measures the round$-$trip time, records packet loss, and

prints a statistical summary of the echo reply packets received $($the minimum, maximum, and the mean of

the round$-$trip times and in some versions the standard deviation of the mean$)$
