Ping is a program that sends a series of packets over a 
network or the Internet to a specific computer in order to 
generate a response from that computer. The other computer 
responds with an acknowledgment that it received the 
packets. Ping was created to verify whether a specific 
computer on a network or the Internet exists and is 
connected.
