Internet Control Message Protocol - ICMP
If you are relatively new or in-experienced in the Networking field, your first guess at the mention of ICMP protocol would be "Ahaa, the protocol that the Ping command is based on" and you might further define it as a protocol for testing network reachability - Dont worry you are partially correct but I'll pardon you for belittling the great ICMP to just a network tester.Also, if you are relatively experienced, chances are that you will say something like "ICMP is an error-reporting mechanism in the IP layer.
Me: Well yeah error reporting mechanism - Why do you say error reporting or what makes it an error reporting mechanism?
You: "Every where goes mute"
