The PING program is a network utility used to test connectivity between one device and another within a network. PING works by sending small data packets called ICMP Echo Requests to a target address. If the target is reachable, it responds with an ICMP Echo Reply. Through this process, users can determine whether a host is active or not. PING also displays the round-trip time taken by the data packets. This information is useful for understanding basic network performance.
Using PING is simple and can be done through the Command Prompt or Terminal. Users only need to type the ping command followed by an IP address or domain name. After executing the command, the system shows the test results in real time. The main function of PING is to check network connectivity and identify communication issues. PING is also used to measure latency and network stability. Therefore, PING is a fundamental tool for network troubleshooting.
