Analog and Digital
As a technology, analog is the process of taking an audio or video signal (the human voice) and translating it into electronic pulses. Digital on the other hand is breaking the signal into a binary format where the audio or video data is represented by a series of “1″s and “0″s. Simple enough when it’s the deviceanalog or digital phone, fax, modem, or likewisethat does all the converting for you.
With over 5 billion cell phones used across the world, we need to take a closer look at the kind of dangers that owning a cell phone can possess. We are concerned, more than anything, on the fact that this wireless radiation might just be more harmful than we originally thought it to be.
On 31st May, 2011, The International Agency for Research on Cancer submitted a list of all possible carcinogenic materials; substances or exposures. They have concluded radiofrequency electromagnetic field as a possible cause of cancer in humans. These electromagnetic fields fall under Group 2B, the same group as DDT, chloroform, lead and welding fumes. Our cell phones use the same radiofrequency fields to transmit information from one user to the other. The health hazards of this have been studied for quite a long time now and the IARC has concluded the carcinogenic potential of these radio waves. The World Health Organization concluded cell phone radiation as “possibly carcinogenic to humans”, while advising the cell phone users to talk through hands-free devices or texts. The basic aim is to reduce the time we keep the cell phone close to the ear.
