Core Concepts: Network and Internet
Applicable CSTA K-12 CS Standards:
- 1B-NI-04: Model how information is broken down into smaller pieces, transmitted as packets through multiple devices over networks and the Internet, and reassembled at the destination. (P4.4)
Lyrics:
Do do do do do do
Boo boo boo boo-weeee
Roads and sidewalks - Ramps and steps all through our town
When someone brings me packages that’s how they get around
My house has an address so that they can see
Where to put the packages that someone sends to me
Do do do do do do
Boo boo boo boo-weeee
The internet also has a way of moving things around
A network of connected pathways like the roads we have in town
Information travels like packages but how does it get to you
Your laptop, your tablet and your phone… they have addresses too!
IP Address – Yes, that’s it!
They’ve got an IP Address 2x
Spoken: So information travels around the internet in different pathways…right?..like copper wires, fiber optic cables, through the air…
Right…and instead of calling the little bits of information packages…we call them packets.
PACKETS!! Oh, I get it. Packets of information or data travel on all these internet pathways
Right!
Packets are like envelopes wrapped around the data inside
The IP Address on the packet tells the destination…BYE BYE!
When you want to see a great website all you do is click
Your request goes out in a packet through a hub that sends it quick
IP Address…that website has an IP Address 2x
But guess what that website’s big it needs a bunch of packets to get back to you
So pictures, video, and words ride back on many pathways its true
Spoken: You get it? A website has so much information that it splits up into a whole lot of packets and those packets come back to you through whatever pathways they can find. And they know where to go…
I get it! They go to my computer’s IP Address. THAT’S IT!!
Let me tell you a story….
Like if you have a picnic planned for 100 people you know
And they come in kayaks, buses, bikes, and boats but they all know exactly where to go
IP Address…yes that’s it… the mighty IP Addresss
