The Fix-It Bay wall is covered in cards from twelve weeks. Rocket stares at them. "We learned all of this? My head is full!"
Raven points at the first card. "What do you notice about how it started? A computer is a system." She traces a line across the wall. "Every card connects to that one."
Nova glows brightly. "Would you like a hint? You do not need to remember every card. You need to remember how they connect."
A computer is a system of parts working together. Input, processor, memory, storage, output, power and network.
Software tells the hardware what to do. The operating system runs the device. Apps do the jobs. Files hold the work.
Networks connect computers. Wi-Fi is radio. The internet moves information in small pieces called packets.
When something goes wrong, a technician uses a method. Notice. Name it. Test one thing. Write it down. Ask.
Safe fixes are a checklist with a never list. Information is kept safe with passwords, updates, backups and a plan for tricky messages.
A designer starts with the purpose and the person. Then the parts are picked and the trade-offs balanced.
| Weeks | Big idea |
|---|---|
| 1 to 2 | A computer is a system with inputs and outputs |
| 3 to 4 | The processor follows instructions; memory and storage hold the work |
| 5 to 6 | Parts connect through the board and ports; power makes heat |
| 7 to 8 | Software, files and the internet |
| 9 to 10 | The troubleshooting method and safe fixes |
| 11 to 12 | Keeping information safe and designing for a purpose |
A technician proves skill by solving cases. Read each one. Decide what you would check or do first.
| Statement | True or false? |

| Storage keeps files when the power is off. | ? |
| A kid may open a device case to look inside. | ? |
| A backup is a second copy in a different place. | ? |

You did it, Crew Technician! Twelve weeks of cases, all connected. Tomorrow the whole crew celebrates with your Crew Technician badge.
