Introduction: Why Digital Rights Matter
Every time you send a message, post a photo, stream music, or browse a website, you are using digital media — information that is created, stored, and shared using electronic technology. But just because something is easy to copy and share doesn't mean it's always right to do so.
The science of waves makes digital communication possible. Sound waves, light waves, radio waves, and microwaves all carry information across the globe in fractions of a second. With this incredible power comes a set of rights and responsibilities that every digital citizen needs to understand.
Think of the internet like a giant public library. You're free to read and learn from the books, but you can't rip pages out, claim you wrote them, or photocopy an entire book and sell it. Digital media works the same way — access doesn't equal ownership.
What Is Digital Media?
Any content — text, images, audio, video, or data — that is created, distributed, and consumed in a digital (electronic) format.
Digital media includes:
- Text: websites, blogs, e-books, social media posts
- Images: photographs, graphics, memes, digital art
- Audio: music, podcasts, sound effects
- Video: films, YouTube clips, live streams
- Software and code: apps, games, programs
All of these are transmitted using electromagnetic waves (such as radio waves, microwaves, and infrared) or through physical cables that carry electrical or light signals. The science you've studied in this unit — how waves carry energy and information — is the foundation that makes the entire digital world possible.
