ping is a computer gridiron tool used to tryout whether a demanding host is reachable across an IP lattice. It works by sending ICMP “echo request” packet to the target host and listen for ICMP “echo response” replies. ping estimates the round-trip time, largely within milliseconds, and paperwork any packet loss, and prints a statistical summary when finished.

It's primarily used as a connectivity exam.
