Ping
A ping tool is a network utility used to test the reachability of a host and measure the round-trip time for data packets sent to that host. By sending ICMP echo requests (ping packets) and measuring the time it takes to receive a response, the ping tool assesses network connectivity and latency. Results typically show the time taken for each response, packet loss percentage, and overall network performance. Ping tools are fundamental for troubleshooting network issues and assessing network health. They are readily available on most operating systems.
