Program
Ask student for name, scores
Save the name & scores
Add scores
Save scores in sum
Calculate average
save average
print name, scores, average

Name 99, 93, 92

this is all stored in Random Access Memory (RAM)
RAM is a volatile memory - when the power is off, everything that is stored in RAM is erased (temporary memory)

Central Processing Unit
Control Unit and ALU (Arithmetic Logic Unit)
ALU - arithmetic operations and evaluates logical statements
Control Unit - sees through the execution line by line statements of the program (resource management)

Computer Architecture Diagram

Fundamentals of Computer Architecture

Only thing it responds to is an electrical pulse or no electrical pulse
2 states it responds too, so we use a binary system
0-bit
1-bit
Combination of 8 bits is called a byte (megabyte, gigabyte, terabyte, etc...)
byte is a unit of memory
every symbol on a keyboard is called a character
each character is represented by a combination of bits
A - 01010011
Compiler
entire code translation
takes a source code, points out any errors, and when the entire code is correct, it converts the source code into a machine language/binary code/binary language/object code
Interpreter
line by line translation

source code --> compiler/interpreter --> object code
java, c++, etc...                                         01010011010

operating system is a system's program that helps us to work with all the resources of the machine
application software - third party apps that have a specific purpose

Points to Consider for Presentation

Some points I would consider to keep my audience engaged during the presentation:

make eye contact
sound excited
give examples
dont read off slides
be funny

10 slides
20 minutes
30 point font

Software Approach, Top Down Design

One way of coding is to simply have a rough idea of  what you want to do and then start typing a way to produce one huge source file. 

This is a very bad idea.

The resulting code is likely to have many issues with it that include

• Poorly documented code, so very hard to maintain and update 
• "Spaghetti code" which means a tangled mess of jumps and loops all over the code, very hard for someone to understand. Even by the original coder a few days later. 
• Duplication of code, so wasting memory and running speed 
• Very hard to develop by more than one person as there is only one file
• Very hard to debug - the file either works or it doesn't

Systems Thinking

What comes to your mind when you hear the word "system"? What is a system? How does it work?

When I hear "system", I think of a group of objects working together to accomplish a task. A system is a way of doing something that was made to be the fastest and most efficient. 

Name Card - Mission Reflection

1. Empathize - gather ideas and choose 5 best ones
   Define - establish a theme for name card and list possible challenges
   Ideate - make rough sketch of name card and get feedback
   Prototype/Test - make a prototype, get more feedback, and create final version of name card

2. I learned that it takes a long time even to make a simple thing like a name card, and I must frequently gather feedback in order to make my product the best it could possibly be.

3. I contributed towards disruptive innovation because by creating a product while receiving an extremely large amount of feedback after each step of the process, I created a product that is exactly what people want
