The electronics and literally the science that deals with electrons and its applications are almost endless in the industrial field and in the home through the work and services. The electronics is in fact present in almost everything we encounter daily by the pc clock radio, through television and the car. But not everyone knows the history of electronics is very recent and that its changes are constant and continuous innovation thanks to the many scholars who specialize in every possible application.
Precisely for this reason it becomes essential not only for professionals but also for those who are willing or unwilling to having to have to do. The electronics is divided into several main areas of expertise that can be found in analog electronics, industrial electronics, digital electronics and power electronics. The term e is defined as the set of practical and theoretical knowledge leading to design and build equipment capable of processing physical quantities. Unlike electrical electronics is based on low voltage (less than 12 volts) that feed and translated by some devices allow the operation of electronic circuits which in turn consist of components, active and passive, connected by wirer paths through which the circulating currents.

The electronics are closely linked electrotechnics that differ only and exclusively for the scope that the electronic information and then applies the processing of messages and electrical signals while the second manages the design of electric machines and transmission of electric power itself.
The two main areas of electronics, including the four previously identified are those which refer to the analog world and digital world. Words that have now become public domain and I know through television that integrates both technologies in question, they are based on two different principles. The analog electronics is that sector that deals with the transmission of informational message that is time varying and continuously while dealing with the digital transmission of messages that can only take values in some particular moments.
Electronics pioneer Guglielmo Marconi was certainly that developed the test instrument programming radio even if the true innovations were introduced by the British in 1904, John Ambrose Fleming invented the first electronic device with two terminals which he christened thermionic valve. The history of electronics was also a strong trend after World War especially on the radio and its application tip that made her one of the first items of mass consumption of 900. Other strong growth in this discipline occurred during World War II with the invention of the transistor, the active component that began the development of integrated circuits. It is the latter led to the use of electronics in many everyday objects.
