Communication
Although speech is generally accepted as the most advanced form of communication, there are many ways of communication without words . In every known culture , signals, signs, symbols and gestures are commonly utilized as instruments of communication . There is a great deal of agreements among communication scientists as to what each of these methods is and how each differs from the others . For instance , the basic function of any signal is to impact upon the environment in such a way that it attracts attention , as for example the dots & dashes that can be applied to telegraph circuits. Coded to refer to speech , the potential for communication through these dots & dashes short & long intervals as the circuit is broken is very great.
