A ping is a diagnostic tool used to test network connectivity. It works by sending an ICMP echo request message to a device and waiting for an ICMP echo reply. If a reply is received, the device is reachable. Pings also measure response time, which can help identify network delays. In essence, it's like a quick digital mail check to see if someone is online and how long it takes for messages to reach them.
