III. Modes of Receiving Information:
- Audio:
- Definition: Information received through sound or audio signals.
- Examples:
- Radio: Broadcasts audio content such as music, news, and talk shows.
- GSM (Mobile Phones): Allows for voice communication over the phone.
- Video:
- Definition: Information received through visual means, such as images or moving pictures.
- Examples:
- Pictures: Static images that convey information visually.
- Charts: Graphical representations of data used to show trends and patterns.
- Audio-Visual:
- Definition: Information received through a combination of sound and visual elements.
- Examples:
- Television: Provides both audio and visual content, such as TV shows and movies.
