How does ping work? Be as specific as you can

What will be an ideal response?

Ping uses an ICMP Echo Request datagram. If the host at the specified address receives the
Echo request, it responds with an ICMP Echo Reply datagram. For each packet sent, ping
measures the time required for the reply. As each response is received, ping displays the time
between when the ping was sent and the response was received. This is a measure of the net
work performance. Ping has a timeout value for the response. If a response is not received
within that timeout, ping gives up and sends a message indicating that a response was not
received. After all the requests have been sent, the ping utility provides output that summa
rizes the responses. This output includes the success rate and average round-trip time to the
destination.
