- How APIs let digital services exchange selected information
Five-Lesson Path
Hardware vs. Software
Learn the difference between physical equipment, the instructions running on it, and the files you create—with an activity and a practical troubleshooting example.
Files vs. Databases
Compare two ways of keeping information, choose the right fit for a simple task, and see why many applications use both.
Understanding Databases
Learn how information is stored, organized, searched, and updated behind every website, application, and online service you use.
Cloud Computing Explained
Understand what “the cloud” actually means, how remote services reach your devices, and why syncing is not the same as backup.
How APIs Connect Services
Follow a request and response between digital services, then learn what to check before granting a connection access.
How to Use This Path
Start with Lesson 1 if the terms feel new. Each lesson takes about 12–14 minutes and includes a short activity and knowledge check. You can also open the lesson that answers your immediate question.
No account or special software needed
Every activity can be completed remotely using the page itself, a keyboard, a screen reader, or a piece of paper. Practice examples use fictional or non-sensitive information.
