Ivy's Power Tips for Kids

 

	The term 'Ping' comes from the pings given off by submarines to detect other submarines. The ping command sends a packet of information to another computer with a request to send the packet back. It's used to determine the IP of an Internet domain, to see if the site is online and to see how long it takes information to go back and forth between the two computers.
	This window show the results of a ping of ivyjoy.com. What is shows is that four pings were sent, the IP address that responded, the size of the data packet sent, the time to make the round trip in milliseconds, and the number of routers the packet was allowed to go through before being discarded (TTL - Time To Live). The ping statistics summarize the data. Four packets were sent out, four came back, so zero were lost. The minimum, maximum, and average time for the packets to make the round trip. A millisecond is 1/1000 of a second. So the packet of data took about 1/6 second to make the round trip. If you are having trouble with ping, try pinging your own machine. The command "ping localhost" will ping your network card. Hopefully you won't lose any packets and the time will be close to zero. Entering ping without an address will display a list of available options.
