Overflow happens if I enter more than 5 scoops. The cone becomes empty again because it cannot fit more data. The cone demonstrates abstraction because it hides the code and represents memory graphically. I learned that binary and compression both deal with constrained space and efficiency. You need to pack data into compact storage without losing its meaning.

Big Idea2 Notes
Binary numbers use only 0 and 1. They represent on and off. Each digit is called a bit. Computers use binary because they understand on and off signals. With just these two numbers, they can store data and perform calculations. Binary is needed for a computer to function correctly.
Moderate compression is best because it makes the file smaller but still clear. Lossy compression is good for videos or images when small quality loss is not a problem. It is not efficient for important files like documents or medical images. This shows abstraction because we can use compression tools without knowing exactly how they work.
Metadata shows detailed information about data and it helps us to organize data easier. Cleaning data is so important because in order to get a successful result you need a clean code. Bias can happen for example if you choose middle school students instead of the whole school. By processing data we can see patterns and make smarter decisions.
People use steps to work with data. They make rules to study the data and find patterns. This allows them to learn more about the information. When they know more, they can make good choices and solve problems. Learning how to do this is important in today’s world.
Reflection - List :
1.I chose this theme because writing letters is easy and I can write them on both computers.
2. I learned that lists let me store many items in one place and access them easily by their index.
