Developments of Internet of Things in Brazil

By Ricardo Barretto Ferreira, Camila Taliberti and Vitor Koketu da Cunha

In 1960, computers performed around four thousand calculations per second, weighed tons and would cost today USD 1.5 million. Nowadays, a basic smartphone accessible to a significant part of the world’s population contains a coin-sized processor that produces one billion calculations per second.

The technology development led to a miniaturization of processors and hard drives. Today, the integrated circuits use semiconductors of 10 nanometers, which allowed its components to consume less energy, the cost of production to fall sharply and processors to become faster and more efficient1. In 1965, Gordon Moore predicted that the number of transistors in an electric circuit would double every two years. This exponential growth of the processing capacity and data storage became one of the basic pillars of the current digital revolution.
