b. Television:

  • Terrestrial Television: Uses traditional analog or digital signal transmission through airwaves.
  • Cable Television: Uses wired connections to deliver multiple channels to subscribers.
  • Satellite Television: Broadcasts directly to subscribers via satellite signals.

2. Digital Broadcasting:

  • Involves converting sound and images into binary code and transmitting this digitally. It offers clearer picture and sound quality and the ability to broadcast additional content.

3. Online Broadcasting:
