Ping
Ping" is a computer network utility used to test the reachability of a host and to measure the round-trip time for messages sent from the originating host to a destination computer. It works by sending a small data packet to a target device and waiting for a reply, which helps determine if there is a connection and measure the response time, often referred to as latency. A lower latency is better, as it means a faster response time, which is crucial for applications like online gaming.
How it works
Echo request: When you ping a host, your computer sends an ICMP echo request (a small packet of data) to the target IP address or hostname.
Echo reply: If the target device is available and the connection is working, it sends an ICMP echo reply back to your computer.
Measuring latency: The ping utility measures the time it takes for the packet to travel to the destination and return. This is the "round-trip time" or latency.
Reporting results: After sending multiple packets, the command provides a summary that includes the number of packets sent and received, the percentage of packets lost, and the average round-trip time.
