Compilers/Interpreters/Bits and Bytes

Compilers: A compiler is when you have a program and you translate it into Binary all at once. It goes through your finished product in one go, converting it and checking for your errors.

Interpreters: An interpreter translates your program into Binary line by line. You translate each line on it's own.

If you want to be able to leave your laptop while you are translating your program into Binary, compilers are better because it is one big job done at once. For an interpreter you have to take your time translating all of your program line by line. If you have an error in your program while it is compiling, the program will give an error message so you can look through and find what you did wrong. If you want to continue compiling but you don't want your computer to stop at a certain mistake you can put */ on each side so that it becomes a comment and the computer ignores it.

Bits and Bytes: In binary, every 1 is a bit and every 0 is a bit. 8 bits is a byte and these bytes are the amount of storage that you have. Depending on which amount of storage you get, you computer can hold that many bytes of data.

Every character on the key board has a certain code of 1's and 0's that tell the computer what it is. If i press a key, it sends a signal to the computer (through the flow of electrons) to say (for example) they pressed an "A" and then it types it on the screen.

Source Program and Object Program: The source program is your program (java, c++, log) that you have written your instructions for your computer with. This is the program that we can understand easier. When you are done with your code you then you use either a compiler or interpreter to translate it into Binary code. This is now called the object code. It is your program translated into 0s and 1s.

Computer Architecture

Q: What is Computer Architecture?

A: Computer Architecture is how the computer is made and put together, or the build of a computer. This includes chips, batteries, and many other things.

Q: How does the computer understand what I type?

A: When we click a key, it tells the computer to type the letter on the key.

Systems Thinking

A system is the way something works. There are groups that work together to make other groups work and this slowly builds up to be a company or a school. If one of the groups has a problem it effects the system as a whole but if they work together, like they are supposed to, the system can make many things. The cooperation of all groups is really important to the success of the system. In computer science systems is what is behind all of the coding. It organizes everything to make it more convenient for the person coding and faster to use for the user.

Name Card - Mission Reflection

This project was really good because it brought out a lot of your character and personality. I learned how to work together with someone to make a project. If we had more time maybe I would have been able to make mine with more color and ideas. I think that this is a good way to start off the year so everyone learns a bit more about each other.

Prototype/Test

I liked this project because it shows a lot about your personality and what you are interested in.

Ideate

Design Thinking Process - Define

 I will use...
Color: Red
Hobby: Volleyball, traveling, cross country
Favorite Emoji: laughing emoji
Animal: Bear

I'm gonna write my name in red and have a city landscape in the back. On the top I want an airplane and a volleyball and on the bottom a cross country sign and a teddy bear (because I love stuffed animals and bears). 

Design Thinking - Empathize

Color: Red
Hobby: Volleyball, traveling, cross country
Vacation: Japan, Caribbean
Food: Ice cream
Favorite Emoji: laughing emoji
Animal: Bear
Pet: Bunny

Design Thinking Process

1. Empathize - Empathize is coming up with something that the world wants and needs. You think about what do my costumers want.

2. Define - You come up with a problem that you need to solve. Ask the costumers what they want.

3. Ideate - Come up with ideas to solve that problem and see if your customers like your ideas. Get the feed back from your customers and see what else you need to add.

4. Prototype - You make your first model of your product to see how it works and what needs to be fixed. You also show this first model to your customers to see what they like about it and what they think you should change.

5. Test - You take your finished product and test it to see how it works and fix up anything that could be a problem later.
