The Information Age (also known as Era Digital or Era Informática) is the name given to the period in the history of humanity that is linked to information and communication technologies (ICT). The beginning of this period is associated with the digital revolution, although it has its antecedents in technologies such as telephone, radio or television, which made the flow of information become faster than physical movement.
The development of communication and the transmission of information is one of the special characteristics of our civilization since the printing of mobile types was invented around 1450 by Johannes Gutenberg, which, by allowing mass production of books, was a great boost to conservation and transmission of information, ideas and culture.
This impulse was reinforced in the nineteenth century with the appearance of the written press and communication by cable (telegraph and telephone), followed in the 20th century by the appearance of mass media such as radio and television, and finally computer science and the internet, which favor a society based on knowledge (and, at the same time, an economy of knowledge).
At the academic level, information theories are developed, which are general theory of systems and theory of cybernetics, whose function is to study how to reach messages more effectively to an increasingly larger, more critical, demanding or simply saturated and insensitive. The union of telecommunications and the processing of information create the discipline known as telematics.

Athens was a democratic society and the epitome of democracy. Democracy began in Athens with the reforms made by Solon where everyone was given the Right to vote and created a court of appeals to examine cases. Sparta on the hand was dictatorial state where people were divides into the Spartan citizens, free men of trade and the helots or slaves. Citizens were required to serve the military and only the fittest were allowed to live in Sparta. Both states formed democratic government and dictatorial government.
Pollsters refer to people that apply surveys in order to obtain data of their interest and opinions. So, the action 'construct a sample' is aimed to find a smaller group that represents the whole universe of study, because they can't study all the universe, at least it's a small subject that they're investigating.
