II. Non-Electronic Devices:

Definition:
Non-electronic devices do not use electricity or electronic circuits to function. They are typically used for manual tasks or to provide information without the use of modern technology.
Examples:
- Books: Physical items containing written information or stories.
- Paper Maps: Used for navigation and showing geographical locations.
- Whiteboards: Used for writing and drawing information manually.
- Printed Newspapers: Provide news and information in a physical format.
- Clocks: Used to measure and show time manually.

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.
