Internet Protocol (IP)

What is a protocol?The established procedure of data transmission between devices. What is an Internet Protocol (IP) address?The number assigned to each device that uses the Internet Protocol for use in the internet. How is it organized hierarchically?The first two series of numbers (first 2 bytes) identify the network and type of network, and the second two series of numbers (second 2 bytes) identify the host, or the specific device on that network How many bits are in an IPv4 address?32 bitsHow many IPv4 addresses does that mean there are?  4,294,967,296 addresses What is the difference between IPv6 and IPv4.  IPv4 is 4 bytes (32 bits) and IPv6 is 8 bytes (128 bits), meaning IPv6 can have many more addresses Why do we need IPv6?Because we are running out of available IPv4 addresses What is an IP packet?Any packet that contains metadata that is used for transfer. What is the difference between an IP address and an IP Packet?An IP address is an identifier for a device on the internet,…

Koan 7 Summary

Koan 7 outlines the comprehensible speed in which information is transferred across the world, in one instance saying "The digital X-ray moves back and forth across the world faster than a physical X-ray could be moved between floors of the hospital." 
Argue if you agree that it is a “truth” and if it will always be a “truth.”

I believe that I understand the transfer speed of data across the world more than most, but it is still a truth that I do not know the time it would take for a cell phone video in India to reach Canada. I do not believe that it will always be a truth because there must be a database somewhere that measures transfer speeds through intercontinental submarine cables, but the transfer speeds may become harder to keep track of over time as private intercontinental cables may arise. 
How does this koan intersect with your life as a student?

October 2018 Quiz Corrections

Link to Quiz
Choose at least 5 questions, if you got it wrong explain what the right answer would be and why, or pick a question that was tricky and explain why someone else might have gotten it wrong
When the number of bits is not large enough to hold the number - what happens?  I got this one incorrect, saying that a program will stop running and produce an error message; but in fact the higher order bits will be lost.  What is source code?  I got this one incorrect by guessing incorrectly; but the correct answer is Program instructions that must be translated by a compiler, interpreter, or assembler into object code before execution.  _ is not equal to (comparison operator) I got this correct, saying !=; but I can see people getting mixed up and saying =! instead.  When communicating within a network, a few things are important. Of the list below, which is most important?  I got this correct, saying timing; however, I could see how someone could get it wrong by forgetting about the way …

3-D Metal Printing Artificial Embryos Genetic Fortune-Telling 
Which ones did you find most interesting in terms of impact on society, culture, or economy?

Genetic Fortune-Telling Could change the way we look at each other, chose our romantic partners, divide our society, and those who do the fortune telling could become very wealthy very quickly, and possibly monopolize Babel-Fish Earbuds The ability to communicate with those who speak other languages with a real time translator, after the reliability issues are resolved, could mean that learning new languages could be less (or more, to develop the technology) useful, and could increase the communications between foreign societies, and therefore changing the worldwide culture, and then the economy, as international business would have one less barrier. 
Which did you find the most interesting on a personal level?

Internet​ ​is​ ​for​ ​everyone​ ​-​ ​but​ ​it​ ​won't​ ​be​ ​if it cannot keep up with the explosive demand for its services (Challenge 3)
A few years ago, I was unsatisfied with my internet speeds for playing video games, and I did some research until I found fiber, which would significantly increase my download and upload speeds. I looked for fiber in my area here, but was disappointing when I learned that it was not offered in my area. At that time we believed that my issues were caused by lacking enough bandwidth for me to play online, whilst others in the house live stream movies. What I learned after more research, was that I could purchase a router and extend the wireless network strength in my area of the house. I also had been wanting to get Ethernet for a while, but believed that running wires all through the house would be difficult. After consulting my dad, we decided on purchasing a router that doubled as an Ethernet switch, and some Ethernet cables. After the setup, …

Chatham Marconi Maritime Center Field Trip Feedback

What struck you the most about our trip to Chatham Marconi Maritime Center? Which exhibits did you find most interesting - and why?. If there were sections that you did not really get much out of can you give an idea of what could be changed - and how? The staff at CMMC would like feedback so they can make changes for future visits. I would also like to know if this is a trip that is worth keeping. Be specific please...no lame answers.
