Answer: Ping command in networking is a frequently used command to test if an IP Address or domain name exist in the network.
Ping is a tool, a software utility that is used to verify that a particular IP address e.g “10.17.18.97” or domain name e.g. “interviewsansar.com” exist into the network and can accept requests.
