What They Teach Kids In School These Days…

Logo of the PlayStation Network First the front story. I was playing a multiplayer game on Playstation. The basic thought was that someone got mad at my play style and decided to call attention to my connection (which I’ll point out, is Time Warner and even though it usually fails me, it was surprisingly good during this story). So this person with the PSN of “KIoey” decided to rag on how I lag, and that’s why I was good and I basically told them that if they stunk at shooting, then quit complaining. Then I decided to tell them that their “ping” probably sucked too.

The response brought on utter shock, and profound laughter.

This person actually wrote back to me that said: “Ping is not a measurement of latency, but your connection to your DNS.”

WOW. We’re talking jaw-dropping wow. If this is what they teach in school for IT/IS, then it’s no wonder college grads can’t get jobs. And in this economy, you better know the basics of networking 101. The first is the definition of “ping”.

Ping is a computer network administration utility used to test the reachability of a host on an Internet Protocol (IP) network and to measure the round-trip time for messages sent from the originating host to a destination computer. The name comes from active sonar terminology.

Another way I taught it when I was a teaching assistant is to think about it as the tracking of delivery of a package. Ping is equivalent to the time it takes from the shipper to send it to the recipient and get a delivery response mailer saying that the package has indeed made it to the destination. To explain it in a little more technical but still in layman’s terms, the idea is to get a single packet from one computer to another, and then get a response where the summation of time of travel is defined by ping. Basics of networking.

Now what Kloey was speaking of on DNS has no validation. DNS means domain name system. This was created long after ping even existed and basically is the renaming of a alphanumeric word choice that is translated to an IP address. So if you type in “google.com”, it actually is translated into an IP address that hosts that data and you’re directed to that place. Ping, has nothing to do with anything here.

So, “KIoey”, I hate to break it to you but if that’s the knowledge you have, it’s going to be tough to get a job during these times. Seriously. And it probably might suffice to actually learn the basics about computer networks next time before throwing out bad knowledge.
