ICMP is an extension to the Internet Protocol (IP) that supports packets containing error, control, and 
informational messages. The PING command, for example, uses ICMP to test an Internet connection.

The method or protocol by which data is sent from one computer to another on the Internet. Each computer 
(known as a host) on the Internet has at least one IP address that uniquely identifies it among all other 
computers on the Internet. When you send or receive data (for example, an e-mail note or a Web page), the 
message gets divided into little chunks called packets. Each of these packets contains both the sender's 
Internet address and the receiver's address. Any packet is sent first to a gateway computer that understands a 
small part of the Internet. The gateway computer reads the destination address and forwards the packet to an 
adjacent gateway that in turn reads the destination address and so forth across the Internet until one gateway 
recognizes the packet as belonging to a computer within its immediate neighborhood or domain. That
