Explore Task Update

Yesterday I finalized my decision, and began research. I have found two good websites that I will use that tell me how it works and what technology it uses. Today I will research more on some possible negative and positive affects of my topic, which I think is going to be the hardest part.

Submarine Cables

1. Is it true that sharks biting the cables is a problem?

  • Cables do fail pretty often, but most of the time it gets cut or snagged by a fishing boat, or gets destroyed by natural occurrences such as earthquakes or strong tides.
2. Cables can break just by wearing out - but what are some other things that cause them to break?

  • Boats or submarines can cut them, as well as other natural disaster such as a tidal wave or earthquake.
3. Who uses submarine cables?

  • Everybody who uses the internet uses these cables, especially if you are trying to reach a server that is on another continent. 
4. How thick is a cable?

  • A cable is typically the diameter of a garden hose but the fibers inside them are about as thick as a human hair.
5. How does fiber-optic technology work with the cables?

  • Lasers fire light down the fibers and a receptor on the other end of the cable picks it up. Since the speed of light is very fast, it does not take long at all, even on the longest cables.
6. What did you find most interesting about the cables?

  • I thought it was crazy just how many they are and that so many people don't even know they exist. I also thought the fiber optic technology was really cool because I hear about it in commercials all the time but never really know what it means.

IP Blog Post

  1. What is a protocol?
    1. The official procedure or system of rules governing affairs of state or diplomatic occasions.
  2. What is an Internet Protocol (IP) address?
    1. An IP address is a label which is used to identify one or more devices on a computer network, such as the internet. It is comparable to a postal address. An IP address is a long number written in binary. Devices that use an IP address use the internet protocol to communicate.
  3. How is it organized hierarchically?
    1. An IP address is divided into a network portion and a host portion. Gateways use only the network portion until an IP data gram reaches a gateway that can deliver it directly.
  4. How many bits are in an IPv4 address?
    1. 32
  5. How many IPv4 addresses does that mean there are?  
    1. 4,000,000,000
  6. What is the difference between IPv6 and IPv4.  
    1. IPv4 is 32 bit binary number while IPv6 is 128 bit binary number address. IPv4 address are separated by periods while IPv6 address are separated by colons.
  7. Why do we need IPv6?
    1. IPv6 means that there are more unique combinations than can be created by IPv4
  8. What is an IP packet?
    1. a packet is a container or box that carries data over a TCP/IP network and internetworks.
  9. What is the difference between an IP address and an IP Packet?
    1. An IP address is a sequence of numbers used to identify a device on an IP network. An IP packet contains an IP address AND the data intended for the machine identified by the IP address.
  10. What is the purpose of the Domain Name System (DNS)?
    1. They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses. Sort of like a phone book for computers. We know websites as domain names, but computers know their IP adresses.

Internet is for Everyone

1.) Internet is for everyone - but it won't be if it isn't affordable by all that wish to partake of its services, so we must dedicate ourselves to making the Internet as affordable as other infrastructures so critical to our well-being.

Internet is now a necessity, and it is something that everybody needs in modern day life. Everyday tasks, such as registering a vehicle, obtaining a permit, etc... is now done online. Also, in terms of education, kids who are able to afford technology have a massive advantage over kids who can't because of the many resources that exist online.

2.) Internet is for everyone - but it won't be if it is too complex to be used easily by everyone. Let us dedicate ourselves to the task of simplifying the Internet's interfaces and to educating all that are interested in its use.

Internet is a great tool but it isn't fair if everyone has pay to take classes to learn how to use it. It is very important to make the internet easy and simple to use because the very people who need the internet are the people who don't yet know how to use it. If we make it very complicated and difficult to use than it many people will not get the internet access they need and deserve.

Starting Python

- what have you learned so far? (be specific - it will help you to remember things)

  • I learned how to do basic python like how to store stuff in a variable and how to create strings. This is all new to me because although I did intro to computer programming in 8th grade, that was mostly dag and drop editing, so this is the first time i am learning to write my own code.
- what was one problem you ran into and how did you solve it?

  • One problem that I ran into was when I couldn't figure out how to print a message. Eventually though, I just looked at the exercise and thought it out, tried different things, and in the end it all worked out.
- rate your feelings about your python skill so far (uneasy, excited to learn more, frustrated, feeling competent, etc)

  • I feel like some of this is still a little bit confusing at first but once I get the hang of it, it isn't so bad. I am also excited to learn more and do more cool stuff with code.

What would happen with no internet?

In the world we live in today, internet is no longer a luxury, it is a necessity. Therefore, if the internet were to be shut off temporarily it could have catastrophic results. For starters, many businesses would lose money. Amazon, for example, would not be able to receive orders from customers, or send the goods because airplanes would likely be grounded since they wouldn't be able to communicate with the control towers. Hospitals wouldn't be able to catalog patients or access medical and data records. Many people no longer have landlines, only cell phones, so communication would be nearly impossible. After a few days, crime rates would go up because most people use credit/debit cards nowadays, but ATM machines are down, and banks cant access financial records. Without cash, people would begin to steal the things they need like food, water, and gas.

Input, Storage, Process, Output

My problem- I often times find myself looking for something but then I am not even sure if it is at my house. It would be so much easier if my computer knew where everything was at all times.

- What is the input?

  • The input is the information that is sent into a computer. It is a way to get information from the outside world into the computer.
  • In my scenario, the input would be a GPS location so the computer knows where the thing is that I am looking for.
  • Examples of input:
    • Keyboard
    • Camera
    • Mouse
    • Touchscreen
    • Microphone
- What is stored?

  • After information is input into the computer, it must be stored in order to be processed then output. Sometimes this is done permanently, in a hard drive, and sometimes this is done temporarily in RAM.
  • In my problem, the GPS signal is stored in RAM to be processed later to determine where the object is
- What is processed?

  • Upon being stored, information must be processed using a series of mathematical algorithms. This is how the computer is able to interpret and understand the input.
  • In my problem, the GPS signal is processed so the computer knows the exact coordinates of the object I am looking for.
- What is output?

  • Output is generally what we see as the user. For instance, the output we are used to would be either sound or the visuals of a screen.
  • In my problem, the output is a visual on a screen, along with the GPS coordinates of where the object I am looking for
