What does ping do in networking?

Explanation:
Ping is a diagnostic tool that checks whether one host can be reached from another. It works by sending an ICMP Echo Request and waiting for an ICMP Echo Reply. If a reply comes back, you know the path to the host exists and you can gauge round-trip time and packet loss, which helps assess connectivity and latency. It doesn’t send error reports to an administrator, it doesn’t reset a connection, and it doesn’t encrypt data; it simply tests reachability with a small diagnostic message.
