How computers run apps
Key ideas
- Apps can help users write documents, communicate, play games, edit photos, manage schedules, or navigate with maps.
- When an app opens, the device loads part of it into memory so the CPU can process instructions and respond to user input.
- Storage keeps programs and files when the device is off, while memory helps the device work with them while they are active.
Software you use every day
Examples to discuss
- Messaging or email apps help people communicate quickly.
- Calendar, maps, note-taking, or school apps help people stay organized.
- Streaming, photo, or banking apps help with entertainment, creativity, or everyday tasks.
Malware and protection
What to explain
- Malware is harmful software designed to damage systems, steal information, spy on users, or disrupt normal operation.

Barcodes, QR codes, and RFID
Explain what these digital codes or tags are, what information they contain, and where they are used.
Barcode
- A barcode is a machine-readable pattern of lines and spaces that usually stores an identifying number.
- Barcodes are often used on store products, library books, shipping labels, and inventory systems.
QR code
- A QR code is a two-dimensional code that can store more data such as text, website links, contact details, or app links.
- QR codes are often used for menus, sign-ins, tickets, payments, and quick website access.
RFID tag
- An RFID tag uses radio signals to share an identifying code or stored data with a reader without needing a direct scan line.
- RFID is often used in key cards, toll tags, inventory tracking, transit cards, and some security systems.
