What is Computer Memory?
🏫 Think of it like School Lockers!
Just like you have a locker at school to store your backpack, books, and lunch, computers have "memory boxes" (we call them variables) to store information like numbers, words, and pictures!
Every piece of information your computer uses gets stored in these special boxes. Each box has a name (like a locker number) and can hold one thing at a time! 🎯

✅ Yes/No Box (Boolean)
Stores simple yes/no answers like "Is it raining?" or "Did you finish homework?"
finishedHomework = false
📋 List Box (Array)
Like a shopping list! Stores multiple things together like your favorite colors or friends' names!
luckyNumbers = [7, 13, 21]
Why Are Memory Boxes Important?
🎮 Like Saving Your Game!
Imagine playing your favorite video game but you can't save your progress! Memory boxes let programs remember important information - like your high score, where you left off, or your character's name. Without memory, computers would forget everything instantly! 😱
