Digital Media
Digital media refers to content created and distributed through digital platforms, including images, videos, music, and interactive apps.
Representation of Digital Media:
- Images: Stored as grids of pixels, each with color codes.
- Videos: Sequences of image frames with synchronized audio.
- Audio: Sampled waveforms encoded in formats like MP3 or WAV.
Compression:
To save space and enable faster transmission over the Internet, digital media is often compressed:
- Lossy Compression: Reduces file size by discarding some Data (e.g., JPEG, MP3).
- Lossless Compression: Retains all original Data (e.g., PNG, FLAC).
Ethical Concerns:
- Copyright violations and piracy.
- Misinformation and deepfakes created using programming tools.
- Accessibility of digital content to all users.
