I thought it was common knowledge

If you're interested in the specific details you should check out more credible sources since I'm not an expert in those fields .

I'll give a few examples:
1. Our organs sends information to other organs using neurotransmitters and electricity.
2. Plants produce smell to indicate that there are flowers or fruits of varying types etc.
3. Stars give off signals that lets us know how old, big or hot they are etc.
4. Your electrical devices are sending information through electricity, radio waves, light, infrared etc.
The list goes on.
