Fire Station
Ding ding ding! The Fire Station alarm is ringing! A real fire crew never waits in line — everyone acts AT THE SAME TIME! That is PARALLELISM! Toggle your heroes ON and OFF, pick HOW they move, and sound the alarm! Today YOU are the Fire Chief! 🚒

⚡ What is AT THE SAME TIME?

When the fire alarm rings, the crew does not stand in a line! The dog barks, the siren wails, and the truck rolls — all AT THE SAME TIME! Doing many things together is called PARALLELISM. Computers love it: your tablet can play music, check messages, and run a game — all at once! You choose WHO is ON, and HOW they move — one by one (slow) or all at once (FAST)! ⚡

🔗 You already learned SEQUENCE (one after another), LOOPS (repeat again), VARIABLES (memory boxes), BOOLEAN LOGIC (AND/OR), DECOMPOSITION (break it down), and EVENTS (WHEN–DO). Now learn PARALLELISM — many things AT THE SAME TIME! ⚡
