Discuss the functionality of PING.
What will be an ideal response?
PING is a TCP/IP application that sends datagrams once every second in the hope of an echo response from the machine being PINGed. If the machine is connected and running a TCP/IP protocol stack, it should respond to the PING datagram with a datagram of its own. If PING encounters an error condition, an ICMP message is returned. PING displays the time of the return response in milliseconds or one of several error messages (request timed out, destination host unreachable, etc.). PING can be used to simply determine the IP address of a site if you know its URL.
