An Internet program Internet Control Message Protocol [ICMP] used to determine whether a specific IP address is accessible or online. It is a network application that uses User Datagram Protocol UDP to verify reachability of another host on the connected network. (It works by sending a packet to the specified address and waiting for a reply. PING is used primarily to troubleshoot Internet connections. In addition, PING reports the number of hops required to connect two Internet hosts. There are both freeware and shareware PING utilities available for personal computers (PCs)) |
