Ping
The PING (Packet Internet Groper) tool is a simple network utility used to test the reachability and connectivity of a network host, such as a website or a server. The PING tool sends a series of Internet Control Message Protocol (ICMP) Echo Request packets to the host and measures the time it takes for the host to respond with an Echo Reply.
The PING tool can verify that a host is up and running, measure the network latency between two hosts, or diagnose network connectivity problems. The results of a PING test show the round-trip time for packets to travel from your computer to the target host and back and the number of packets lost along the way.
PING is available on most operating systems, including Windows, macOS, and Linux. It can be run from the command line or terminal, and the results of a PING test can be used to diagnose network problems or monitor a network's health.
