The Ping command is an essential network tool used to test network connectivity between two systems. The command sends an Internet Control Message Protocol (ICMP) echo request packet to a designated address and waits for a response. If the address responds, the packet is sent back along with details such as latency, packet size, and other metrics. The Ping command is helpful in troubleshooting and monitoring networks, as it can reveal issues such as packet loss and latency issues. Learn more about Ping command.
