Having spent a little time in the Zoom session, I realized that I have never given much thought to the internet and how it works. I now know that there are senders that send information, routers that carry the information and receivers that take those bits and recreate the message/information. Reminds me of Willy Wonka when he takes the big chocolate bar and transmits it in tiny pieces above the people's heads and puts it back together in a smaller size on the TV receiver.

# data[].attributes.body
I wonder what happens when the receiver is unable to put the message back together. In the activity we participated in, we got the answer if we could not figure it out, but what happens to the message if it is undelivered or 'scrambled'?

# data[].attributes.body
I found both the article and the video to be easy to understand and I really enjoyed both. I learned about the connections and the network Hubs. In college in our dorm room we needed to have an ethernet hub that we all plugged our ethernet cables into. It was interesting to be able to make that connection to my experiences. I also learned about TCP, transmission control protocol. My previous wonder was about the 'scrambled' message and I discovered that TCP is what sorts the information and requests for a resend if all the information did not arrive.

I know that once you delete something that you post online, it's not necessarily "gone". It's still out there in cyberspace and you can't take it back, so teaching students internet safety and responsibility is extremely important, especially with the potential for cyberbullying. I also know that routers take information and that information travels in a network.

# data[].attributes.body
I wonder why there are always so many cyber attacks on banks and hospitals? With all this technology, shouldn't there be some way to protect our data, so it's not so vulnerable? I keep thinking of all the different ways I've had to create a password. You'd think that the experts would be able to make it "foolproof" or "hack-proof". Is that even possible?

# data[].attributes.body
I found the article interesting in how it explained the evolution of the internet. The video was helpful in explaining in how the data gets sent, particularly with the space shuttle example, and how a song from Spotify plays on your device, which many times we assume it's direct, which it is not.

# data[].attributes.body
What I know about networks and the internet is that anything stored and put onto it will be on there forever. It can be accessed by the proper people even if it is deleted. I also know that it can lag based on many factors. There could be too many people accessing the routers, parts of the information is still not connecting or even issues with construction making the signal weak. It is such a complex concept yet completely a part of everyones everyday life.

# data[].attributes.body
I always wonder what the internet will manifest to as we grow older. If it will become even more a part of our lives or maybe even cease to exist completley. I wonder if we will one day have world access to the internet instead of just wifi and hot spots?

# data[].attributes.body
It is so facinating that the internet started with just two computers. I recall actaully having a home desktop when I was a kid. The internet had to be connected to my phoneline and the house phone could not be used simultaneously. I compare that to now where I can get internet signal on my phone in most places. The article kinda mapped that out for me. I also didnt really realize until now that the internet would be soo slow if it worked in sending whole information instead of packets.

# data[].attributes.body
I learned that a computer use to just be connected to another in the early days. I remember phases of the internet like the article stated. I had a home desktop that had to be connected to the internet with a long cord. The cord was also connected to the home phone line and if the internet was being used then the phone couldn't be used. I also learned that spliting information up into packets actually allows us to get information faster. Sending it whole would only dely the information.

# data[].attributes.body
What I know about networks and the internet is that people manage and keep it running but there is not one entity that manages the entire internet. Moreover, there are packages of information bits that travel down various routes via routers that are interconnected, delivering digital data to its users.

# data[].attributes.body
What I wonder is what is the purpose of a server and how does it fit into the big picture of the internet?

# data[].attributes.body
I learned that the evolution of networking actually started very simply - with just two computers connected by a direct wire using electrical voltages to represent 1s and 0s. This could be a great starting point for teaching kids, as we could create an art project where two students first exchange "binary messages" using simple patterns (like dots and dashes) before we move into more complex network concepts.

The video provides a brilliant analogy comparing data packets to moving a space shuttle - explaining how large items need to be broken down into smaller pieces for transport, just like a large image or song must be broken into packets. This could inspire a creative art lesson where students create a large mural that must be "transported" across the classroom in smaller pieces, with each piece being labeled as a packet - much like a real space shuttle's parts need tracking and reassembly.

# data[].attributes.body
To be honest I never really gave any thought about how networks and internet worked together. What I learned through our activity and the zoom is that the internet is made up of information that is being sent and received.

# data[].attributes.body
I wonder what the future holds for the advancement of the internet and networks. What things will my student be able to accomplish with growing up in a world were the internet has been and here and being used in the classroom and their daily lives.

# data[].attributes.body
I know that networks are groups of devices that share information between each other. The internet is a worldwide network that connects smaller networks together. An example would be like a giant spider web. Each thread of the web is a connection to another network. All the threads are intertwined together.

# data[].attributes.body
Is the internet just like the universe where it keeps expanding and growing as time continues? Is it possible to "end" the internet and start over? How can we eliminate/clean the internet of "trash"?

# data[].attributes.body
I already knew that computers had their own address but I didn't realize how important it this was, to make sure information is shared to the right computer. Eye opening was the analogy of how a packet of information travels and comparing it to a car traveling in traffic. I, also, learned that there isn't a direct path for information to travel but instead there are options to help keep the flow of information.

# data[].attributes.body
Reading the article and watching the video helped me realize how important that sending and receiving is among the network.

It seemed very similar to sending an e-mail with having the correct address. If you have a typo in the e-mail address it doesn't go to the correct place. The a

What I know about the internet is that it takes information from one location to another. A good visual for me is when in Charlie and the Chocolate Factory when Mike TV is teleported into the TV. Wonka casually explains to the mom that her son is in a million tiny little pieces above her head as she panics. The internet, for me, is that transfer of information from one place to another.

# data[].attributes.body
What I wonder about the internet is how do these networks (mostly) work seamlessly? Its vast beyond my comprehension that I can send my sister a picture of my children from California to Missouri in seconds.

# data[].attributes.body
The visual in "The Internet, Routing, and Reliability" did answer my question. Seeing how the networks work together to to transfer information made the concept a little more digestible for me.

# data[].attributes.body
I hadn't considered how the Internet works. I just knew that if I did a search, I would get information from various sources. After our discussion on January 7th, I now know that we send information, which routers then take and carry. Then, receivers take those bits of information and recreate what was sent. This was shown in the game we played at the beginning of the Zoom meeting.

# data[].attributes.body
What I wonder is what happens when I click on a link and I get an error message stating information is no longer available. Has it been taken down because it is false or the information no longer applies? I also question when I get an error message telling me the message is undeliverable.

# data[].attributes.body
What I learned is how the internet functions and gets the information or message from one place to another. I had heard about routers and receivers, but I didn't know how they applied to the Internet. It was enlightening to find out what their function was in transmitting information or a message.

# data[].attributes.body
As someone who "existed" before internet, the way information (on any subject) is instantly available and sent through the network still amazes me. What do I know about the network? I know it allows us to request, send, and receive information on any subject. We get the information almost instantly...after it's traveled through a web of smaller networks.

# data[].attributes.body
With all the information coming and going, right at our fingertips, it should cause us to pause. Is it safe? What information are we accidentally sending that we don't want to send? How hard would it be to take the entire network down?

How vulnerable are we, and could our society function without the network and the internet anymore?

# data[].attributes.body
Okay! I feel like I understand the "magic" of network and internet a bit better. I really liked the part where it explained that information only goes to the computer "address," but it passed along and prevented from being "read" because it was only meant for that "address."

Good read.

# data[].attributes.body
I know that information travels, and that a lot of information is available quickly. I know that information goes from one location to another, and that there are lots of moving bits and pieces to networks and the internet.

# data[].attributes.body
I wonder how cyber attacks/hacking works. How is it possible that a complex network can also be easily manipulated? I also wonder how it's possible that the information I access can be accessed by another person at the same time. I also wonder how safe the internet is, or how to be safe on the internet.

# data[].attributes.body
I learned how digital information travels. Specifically, in the video, I learned that information doesn't have one direct line/direct path, and that there are tens and billions of bits that carry information.

I also learned about a handful of words related to networks and the internet that I have maybe heard of before -- but didn't quite understand what they were in the world of tech. For example, I have heard about "cabling", "switch", and "hub", but not in the context of tech! It was neat to read on these.

# data[].attributes.body
What I recently learned in the CS zoom training is that data gets broken down into small packets that travel independently through the network, allowing multiple users to share the same network infrastructure simultaneously.

# data[].attributes.body
I wonder how data travels around the globe so quickly and what security measures are set in place to protect data, and last how new technologies such as 5G are impacting connectivity?

# data[].attributes.body
I found both the video and article to be very interesting and educational. I may even show the video to my students to help explain better how the internet works! In the video I learned that whenever you request a song on your device, such a Spotify, it sends a song broken up into many packets. When your packets arrive, TCP does a full  inventory and sends back acknowledgments of each packet received. If all packets are there, TCP  signs for your delivery and you’re done.

In the article I learned that each computer has a network interface card (NIC) that manages data encapsulation. Errors during data transmission can occur, so a check-field is added to each data frame to detect any issues. The evolution of these networks helped establish the internet protocol, marking significant progress over several decades in networking technology.

# data[].attributes.body
I don't think I know very much about networks and the internet. I do know that networks connect all the information traveling through the internet. I believe that the information is broken up into parts and then put back together.

# data[].attributes.body
I wonder how it actually works. What causes it to split the information up and move it throughout the system. Code? How does someone understand what to write to make it do what it's supposed to do?

# data[].attributes.body
The article and the video discuss how computers work together in networks, like the internet to make life easier for teachers like us! Long ago, computers were connected with wires, but this has changed. Connections went to the rings and hubs and have then evolved into the hubs and switches (and these make the internet more efficient)--which I totally take for granted.

# data[].attributes.body
What I know is networks and the internet connect computers and devices so they can share information and resources. Networks use special devices like routers and cables to send data, and the internet relies on these connections to work.

# data[].attributes.body
I wonder how the internet connects so many people and devices around the world. How does it work so fast? How do networks keep our information safe?

# data[].attributes.body
Just wow. I know that computers can connect to share information, and these connections create networks. The internet is the biggest network, powering things like electricity, water, transportation, and even schools. Early networks connected computers directly, but as more were added, new methods like rings, buses, and ethernet made sharing easier. Tools like hubs, switches, and special cables helped networks grow and work better. Networking is what makes the internet possible today!

As a kindergarten teacher, I approach the concepts of networks and the internet with enthusiasm and simplicity, even though I don’t have all the technical details down at a computer scientist level. Using books like Hello Ruby: Expedition to the Internet and Journey Inside the Computer: Adventures in Computing, I’m able to provide my students with a friendly, imaginative introduction to these complex topics. I explain that a network is like a group of computers or devices holding hands, passing messages to each other to share information. I describe the internet as a giant playground where computers can meet, talk, and share pictures, videos, or even play games together. By breaking it down into concepts they can relate to—like how friends share toys and messages—I help them build a simple understanding of how computers communicate with each other.

While I don’t know every intricate detail about how networks and the internet function on a technical level, I have a general grasp of the big picture, which I use to inspire curiosity and exploration in my students. I focus on foundational concepts like communication, connection, and sharing in a way that sparks their natural curiosity and encourages problem-solving. I also introduce the idea that, just like we need to follow rules when playing with friends, we need to use the internet safely. Even though I’m still learning and growing in my own understanding of computer science, I’m committed to continuing my journey. As I continue my own learning in computer science, I will grow alongside my students, expanding my understanding of these systems so that I can continue to guide them on their path toward exploring the world of technology with confidence and curiosity!

As a kindergarten teacher, I often find myself marveling at the incredible ways that networks and the internet allow people and computers to connect, even across the world. I wonder how all the information and messages travel so quickly from one computer to another, like magic happening behind the scenes. It’s amazing to think about how millions of computers can talk to each other through invisible wires and signals, sharing knowledge and connecting us in ways we never could have imagined just a few decades ago. I also wonder about the safety of it all—how do we make sure that everyone is using the internet in a safe and kind way, especially when young children start exploring this vast digital world?

What excites me most is the endless possibilities the internet holds for my students as they grow. I wonder how, as they learn more about technology, they will unlock new ways to use the internet for creativity, learning, and problem-solving. It’s fascinating to think about how we, as teachers, can guide them in understanding these concepts, even at such an early age. I’m excited to explore these questions alongside my students, nurturing their curiosity and helping them start their own journeys in understanding the digital world. Even though I don’t have all the answers yet, I’m eager to discover them with my young learners and watch them grow into confident, thoughtful digital citizens.

After reading the article "The Journey of Networking," I have gained a deeper understanding of how networks and the internet evolved and the important role they play in our daily lives. One key takeaway is that the internet is the largest global network of interconnected devices, and its impact goes beyond just communication—it's crucial for essential systems like electricity, water distribution, and even banking. The article also clarified the evolution of network structures, such as the shift from fully meshed networks to more efficient designs like ring and bus topologies. These changes helped solve the challenges of connecting multiple computers, as seen in early networking with Ethernet cables and the development of hubs and switches to improve communication efficiency.

I also learned how data is transferred within these networks. The concept of "encapsulation" stood out to me, where data is packaged with source and destination addresses, much like sending a letter in an envelope, ensuring that the right computer receives the right information. While the article discussed advanced technical details, the key takeaway for me as a kindergarten teacher is how networks function to connect computers and devices, allowing information to flow seamlessly between them. This knowledge helps me better understand the complex systems behind the internet, even as I continue to explore and learn more about the technical aspects in the future.

I know the internet can be a beautiful tool if we allow it to be! I remember having a designated "computer room" and using my computer to be so slow from downloading music. As far as networks, I think of the "web" that the internet is. It connects ideas, people etc.

Something I wonder about the internet is how an I teach my students to use it for GOOD! Often companies are not in the business of helping consumers have a healthy relationship with the internet.
