Communication

 Communication is the key to life. Without communication, it would be chaos. Communication ranges all the way back to the caveman era. The first form of communication was cave paintings and now we all have phones.  David Alter had created Telegrams. It was the first big advancement in communication.  A telegraph is a communication system that sends information by making and breaking an electrical connection. It is most associated with sending electrical current pulses along a wire with Morse code encoding. It was a big advancement that eventually led to the telephone. Alexander Graham Bell is often credited with being the inventor of the telephone since he was awarded the first successful patent. However, there were many other inventors such as Elisha Gray and Antonio Meucci who also developed a talking telegraph.  We advanced so much that we now have Phones!
