Professional presentation has three basic laws that guide the process according Doumont. In the first law, Doumont notes different types of audiences and urges a presenter to adapt, control what is in a presenter’s power, and finally calls for full concentration. The second law takes cognizance of the importance of maximizing on signal-to-noise ratio. In essence, signal-to-noise ratio is a model that ensures, what a presenter communicates from a presenter’s end reaches the audience’s end without hitches.

Filtrating the noise out or compensating for it aim at balancing noise since, “in communication, nothing is neutral,”. The third law requires that a professional presenter to compensate for the loss of information resulting from noise in which, effective redundancy abounds. Finally, to ensure that a presenter follows all the three laws of professional presentation, the author urges the application of the Zeroth Law of Thermodynamics and Robotics. By relaing the Zeroth Laws, Doumont sums that a presenter should have a defined purpose in making a professional presentation.
Device of choice, iPhone 4
When Apple rolled out the iPhone 4 they made a stunning statement, “The biggest thing to happen to iPhone since iPhone,”. This product is outstanding because of a number of features.

Since the iPhone 4 Smartphone is a recent product, exploration into design faults are still lacking. However, in the new future when complete exploration will take effect, the defects of the iPhone 4 will discredit its superiority. A likely start will be monitoring the battery life of the phone since the features of the phone are complex.
