Numerical systems

 Conclusions In conclusion, these communication systems are not necessary to learn, but if you want to learn to use them, you could get a good job as a programmer. Also the morse code can be used to show off with your friends. You will be a more interesting person.

 How I tink we can use the morse code. Today the morse code is'nt something that is used always, because it does'nt need to be used because communication systems are in everywhere. That's why I don't think we can use it in the normal life, but if you are in a place without signal (like a forest or an island) you can try to use the morse code to search for help. Then when i am lost or in an island, i will use the morse code

 Best communication system In my opinion the best system of "communication" is the morse code, because it is the easiest to understand once you know its rules by heart and it is not necessary to learn the alphabet, because you can have a table that contains the entire morse alphabet. When I'm lost without communication, I will use the Morse code.
