Networks: Connecting Neighbors
1.
2. Once upon a time there was a girl named Stacee.
Stacee moved into a new neighborhood (#13 Awesome Way
to be exact) and wanted to connect with her new neighbors
but she wasn’t sure how.
3. As she was sitting outside of her house trying to decide how to
connect with them she saw a truck coming down the road that
said Network. The truck stopped in front of her house.

4. Out jumped a boy named Willie. Willie handed Stacee a
document and told her it was from #28 Awesome Way.
Network
Willie explained to her that if she wanted to send anything
to any of her neighbors all she had to do was send it with
him, and the Network truck, and he would get it to them.
Stacee was so excited. She immediately wrote a response
to #28 Awesome Way and sent it with the Network truck.
5. This happened over and over again. Stacee was having so much
fun sending messages back and forth between #28 Awesome
Way. She decided to try some of her other neighbors as well.
And it Worked!
6. On one of his visits, Willie decided to ask Stacee about all of the
boxes that were still just sitting in front of her house.
Network
Stacee explained to Willie that she just didn’t have room for
them in her new house. But she just couldn’t bear to throw
them out because she might need them in the future.
7. Willie explained to her that in the
neighborhood they had a place called The
Server, where all the neighbors could
store all the stuff they wanted to keep so
their houses wouldn’t get too cluttered. If
she decided she needed something, all
she had to do was let Willie know and he
would bring it to her.
Network
9. Willie began loading all of Stacee’s extra boxes onto the Network
Truck to take to The Server located at #200 Awesome Way.
10. Stacee Wanted to tell her mom all about her new
neighborhood and The Server storage unit. She wrote
up a message, and called for Willie.
Willie explained to Stacee that he could not deliver the
note to her mother because it was out of his
neighborhood. But he could take it to the Router station
and they could find the delivery person that worked in
her mother’s neighborhood.
11. Willie pulled out a map to show Stacee what he meant.

12. Stacee thanked Willie for all of his help in
keeping her connected with all of her friends
and family. She also thanked him for taking her
extra stuff to The Server for storage.
And she
gave him
a big hug!
14. Meet Willie!
Willie is a Network
Administrator for a
local engineering
company. He also
happens to be a friend,
so he let me tag along
with him at work the
other day to teach me
all about how
networks work.
15. Software
As a network Administrator, Willie has
software that allows him to see all activity
that is happening within his LAN.
16. IP Addresses
Computers are like the houses used in the previous story.
Each computer has an address. These addresses are
called Internet Protocol (IP) addresses. They let networks
know where to send information that has been sent.
The IANA is responsible for assigning and coordinating
these addresses across the globe. Clicking on the link
above will take you to their website where you can learn
more about how they distribute addresses, and the
different types of IP addresses.
17. Networks
When two or more computers are
connected, so they can share the same
printer or files, they form a network. These
networks can be done with hard wires, or
even wirelessly.
If the computers are connected without
ever having to go through a router they
would be considered to be a Local Area
Network (LAN). LANs are generally a very
small area, like the computers in your home,
or a computer lab.
In the story, Awesome Way, where Stacee
lived, was an example of an LAN. Within a
school district, each school might be set up
on it’s own LAN, so you can all run down to
the same printer to pick up your copies.
That is a LOT of messy wires!
Willie was in charge of organizing
these wires! Much neater!
18. When you want to connect to another school in
your district you leave your LAN and connect to
another LAN through a device called a router.
Because these LANs are connected by a router, you
are now participating in what is called a Wide Area
Network (WAN)
Router
19. After a WAN you an enter into a wide array of
other networks. Including one of the largest
networks we know, the Internet.
Just like a computer, websites also have IP
addresses. Type the IP address 74.125.225.177
into a web browser and see where it takes you.
20. For most of us, it would be pretty difficult to
remember numbers like this for each website
or computer we wanted to use. We often use
as software called Domain Name Service
(DNS) which attaches a name to all those
numbers. It is much easier to remember
Google.com rather than 74.125.225.177
21. The Florida Center for Instructional Technology
put out an excellent document explaining the
differences between a LAN, a WAN, and the
Internet. It also discusses the advantages and
disadvantages of installing school networks.

22. Servers
Although not required, many
networks have something
called a Server.
Servers can do a lot of things
including store files. If a
computer were to crash,
anything that was saved on
the server from that
computer would still be safe.
Servers can also be
responsible for running
printers and other devices.
23. Connecting Neighbors
In short, Willie sets up networks that keep
people like Adam connected with all of the
people in his network and networks all over the
world. Making it a lot easier to do his job.
