Information Broadcast:
Broadcasting means sharing or sending information to many people at the same time. This is done through tools like radio, television, and the internet. When something is broadcast, it can be heard or seen by people in different places, all at once.
Types of Broadcasting:
- Radio Broadcasting: Radio stations send out sounds (like music or news) through radio waves. People with radios can listen to these broadcasts in their homes, cars, or even on their phones.
- Television (TV) Broadcasting: TV stations send both pictures and sounds. This lets people watch news, shows, or cartoons on their televisions at the same time, no matter where they are.
- Internet Broadcasting: Information can also be shared online through websites, videos, and live streams. People can watch or listen to these broadcasts on their computers, phones, or tablets.
Examples of Information Broadcasts:
