Information can be carried on a radio signal by changing its amplitude,
according to a pattern that the sender and receiver agree on. Information
can be carried on a light beam by changing its amplitude (brightness),
according to a pattern that the sender and receiver agree on.
Information can be carried on a radio signal by changing its frequency,
according to a pattern that the sender and receiver agree on. Information
can be carried on a light beam by changing its frequency (color), according
to a pattern that the sender and receiver agree on.
Digital bits can be carried on a radio signal by simply turning the signal on and off
to denote ones and zeros. Digital bits can be carried on a light beam by simply
turning the light on and off to denote ones and zeros.
Not quite sure what you mean; light itself IS wave.
The clap creates vibrations in the air that eventually reach our ears. A message is then sent to our brains, saying "a clap has occurred."
Depending on the type of neuron, it can take anywhere from 1 to 200 miles per hour to carry a message.
light gates are simple optical circuits that have an opening between an emitter and receiver. If the path between the two is interrupted, a signal is sent to a computer or other data recorder. light gates are typically used for timing and detection.
There are light receptive cells in the backs of our eyes known as cones and rods. To see light the lenses in our eyes contract and expand to focus light onto these cells and from there the information is sent to the brain via optical nerves and processed into light and colour.

I believe you are referring to attachments? They are computer files which is sent along with an e-mail message. The file is not a separate message, but now it is almost universally sent as part of the message to which it is attached.
Optical fiber's main advantage over regular electric cables is that they don't experience electromagnetic interference of any kind, thus allowing signals to be sent where regular cables would get cut off. Another important advantage is that distance affects electric cables' data bandwidth much more severely than it does optic fiber.
the messages were sent by people. there would be towers that a people would drop their messages off at, and the people that were in the towers would then pass the message on, therefor it would travel up and dow the wall
Most email clients (programs that present and handle emails) call the files that are sent along with the message; attachments
because the message was no sent.
Well they are sent through the nervous system.
optical fiber is made from extremely pure glass that is stretched out to a very thin and flexible wire. fiber optic wire is often used in locations of computer networks with a very high load because of the speed of light. it simply uses the same hexidecimal and binary codes to transmit data over the network just like regular Ethernet cables, except much much much faster.

Ooh, so close. Now we have to guess what the message was sent through. A message sent through a telegraph is a wire. A message sent through a chat room or a blog is a post. A message sent through a letter is mail.
Regardless of how or why you sent a text message, once it is sent from your phone it is billed as a sent text message.
No, you can't. Once a message is sent, it can't be unsent.
