Ping is a network utility and a general term used to describe the round-trip time for a small data packet to travel from your device to a target host and back, usually measured in milliseconds (ms). The term originated from sonar terminology and is commonly used to assess whether a device is reachable and how quickly it responds on an IP network. In practice, “pinging” a host involves sending an ICMP echo request and waiting for an ICMP echo reply, with results typically including packet loss, response times, and basic statistics such as minimum, maximum, and average round-trip times.

Key takeaways:

• What it means: A quick check of connectivity and latency between two devices over an IP network.

• How it works: The tool sends ICMP Echo Request packets and measures the time until Echo Reply packets are received. The results reflect reachability and round-trip time.

• Common usage: Troubleshooting network problems, verifying server reachability, and gauging latency for applications like gaming or video calls.
