David Lawrence: Well understanding, I mean understanding why things happen is something that you know some people dig some people couldn*t care less. It*s like you know just I don*t want to be confused by why it works, I just want to know that it does work. And those are the people unfortunately that are most susceptible to the scams that we see on the web. They look at their technology simply as a tool and you know if they can take the hammer and hammer in the nail, they don*t need to know to why the nail doesn*t split the wood they don*t care why the nail doesn*t pull the wood, they just know that it works. And so there are two types of people in the world, there are people that want to know the background to why things work, they want to delve into it, it helps them understand the way the world works around them. And then there are people who simply just want to use technology and anything else in their lives as tools. And I think you fall into the former ladder, alright.

Colleen: Okay well thank you.

David Lawrence: I appreciate the call. Thanks very much for listening to the show, I appreciate it. 180039 online is our telephone number, I happen to be like Colleen I am fascinated with the way things work and I think that helps a little bit because it sort of leads me to questions the things that I see to say well I don*t know how that*s going to end up working into long run, I see how it works now, but gosh I don*t know if it*s going to last, so more in a moment on Online Tonight.

Alright the Geek Speak phrase for this hour is Packet. And we are going to dive into what a packet of data is just a moment. This portion of the show is powered by www.GoDaddy.com. Whenever I need to pump up my web presence, I use www.GoDaddy.com.

Now this hour*s Geek Speak is Packet and a Packet of Data is a group of bytes of data that are sent all at one time. And are sent all at one time in a package, called a Packet and at the beginning of the Packet there is a little number that tells the receiving server that this particular Packet*s code number is X. When it gets to the other end, the data is added up in what*s called the checksum if it equals X then the receiving server assumes that the data got there okay and it asks for the next packet of data. That set of numbers is called the Header. And the Header also tells you where it*s coming from, where it*s going to this are just some directional information there. So imagine one server sending data to another server, it assembles a bunch of data usually about a thousand pieces of data. It puts this Header together, it says hey I am server A and I am sending to server B. It goes to server B and server B says really what was that number associated with this Packet oh it was 75065 and that*s hey that*s what I got. Alright cool so send the next set. You know if that doesn*t equal that then it says could you do me a favor send it again, send it again. Now that we are talking there about TCP/IP, FTP. HTTP on the other hand if the data gets there great, if it doesn*t get there, well too bad reload the page. I mean it*s there are certain forms of sending data around in Packets where they check and then there are certain forms where they do not. That*s why sometimes if a page doesn*t load correctly on the web you simply hit reload and it loads just fine. Something happened in between some glitch occurred and you just get around it by reloading. So there you go Packet of Data that is this hour*s Geek Speak.

Geek Speak is brought to you by our amazing Safety Laser Flare, the rescue laser flare that*s visible up to 20 miles away at night, 3 miles during the day, as your kids go back to school this is a great device for them to have at their disposal, should they go on field trips, if they are allowed late at night, get lost in a new environment, go to www.safetylaser.com and check it out.
