Quiz 1

Question #1: data type to store a price in dollars and cents
I found this question difficult because I didn't know the data type that specifically stored this information, so I had to try and use what I knew about this matter, but I still found it very difficult. I also forgot what type of data the options stored so that didn't help as well.

Question #2: What is the highest decimal value a single byte of data can hold?
I thought this question was hard because I'm not very clear on bytes and how much they can hold and print. I just find it really confusing because I know binary has something to do with it. I know that a byte is 8 bits, but I don't remember how much a byte can hold.

Question #3: The time it takes for a bit of data to travel from the sender to receiver
This question was challenging to me because I didn't know the answer or felt as though I knew something about it. The options also made it more difficult because I don't have a good understanding of l…

10 Breakthrough Technology 2018

Did you already know about any of these innovations? Which ones did you find most interesting in terms of impact on society, culture, or economy? Which did you find the most interesting on a personal level?
The technologies on the article that I already knew about was the 3-D metal printer, babel-fish earphones. Some of the technologies that I found the most interesting were artificial embryos and genetic fortune telling. I thought that the artificial embryos was very interesting because they didn't need an egg or sperm in order to create life. What they did was pick cells from an embryo and placed it in a three denominational scaffold and the cells began to line up and resembled a mouse embryo early in it's development. This is a hint that there could soon be mammals born without an egg at all. I also thought that the genetic fortune telling was cool too because it could predict potential health issues or diseases. This could be very useful because you can treat diseases or h…

Internet Is For Everyone

Two challenges that were most meaningful to me was challenge 1 and challenge 7. Challenge 1 was meaningful because it said that the internet won't be for everyone if it isn't affordable. I think that this is very accurate and important because some people cannot afford things to access the internet such as phones or computers, these things tend to be very expensive. If you live in a first world country, such as America, it seems like almost everyone has a smart phone, but in other parts of the world some people cannot afford things such as these. Also some websites or programs on the internet you have to buy so that is a cost issue as well. I choose challenge 7 because it is something I worry about often. Challenge 7 states that the internet is for everyone but it won't be if user cannot protect their privacy and transactions. This is obviously very troublesome because your information can be found and used and if you buy something online people could get your credit or de…

Marconi Museum Review

What struck me the most about the trip to the Marconi Museum was the actual enigma machine. I thought it was pretty cool, I also thought that the simulation of the enigma machine was cool and it helped me understand how the machine worked. Even after watching the imitation game I didn't understand how enigma worked, but after going I have some concept of how it worked. That was the main thing I got from going to the museum. I didn't really get anything out of the videos and the room with all the phones. Otherwise I had a pretty good day, and I think this field trip was worth keeping because it was interesting and it was fun going to Chatham.

CS50: Fahrenheit

Image
This is my code for converting Fahrenheit to Celsius. This lesson taught me how to do more calculations, and it taught me what some of the variables in the code meant. For example before this program I didn't exactly know what the float command was doing exactly, but know by doing this I have some idea what it is doing. For example float c is saying that c will represent the input from the person. Float f is saying that the variable or symbol "f'" is the same thing as that equation, so that f will equal the conversion of Celsius to Fahrenheit. Then what printf means is to print what is in the parentheses and quote marks. So, what will show up to the person will be "F:__", in the blank space would be a number. But in the code instead of a number it shows %.1f/n, this stands for the product of the formula in float f above, the .1 is a command that there will only be 1 decimal place. Then the f at the end tells that the %.1f/n is connected to the Fahrenheit f…

CS50: "Hello World" Report

Today we worked on the first CS50 lesson "hello world" where we learned the basics of CS50. The goal of this program was to type out "hello, world" and to also create two new folders and three files. During the lesson I learned how to navigate between my files and folders by typing cd and then the name of the file I wanted to enter. I typed my code in the file hello.c and at first I had an error in this code because I forgot the f after print, and when I typed make hello in the terminal window it alerted me that I had an error in my code. To compile my hello code I would then type in "make hello" in the terminal window. Then after that I typed in ./hello, hit enter, then the text "hello world" would be typed out in the next line. My first day using CS50 it seemed like a title wave of new information hit me and it left me a little confused. The second day of using CS50 didn't seem as hard as the first day to be because I was sort of familiar …

Computing Innovation in Damien's Lifetime

The adult that I asked about a computing innovation that had an affect in their lifetime was my dad, Damien Houlihan. My dads answer to, "What computing innovation ha had the most impact on your life?" was a hand held calculator. My dad said that this has affected his life because, "it made me learn how to program devices and allowed me to become an engineer". To compare what I wrote was my innovation was more practical and every day usage that everyone could use, but my dads is more specific and more of a computing innovation because I said a stove/oven.
