The voltaic pile was created by the Italian physicist Alessandro Volta in 1800. This invention was a milestone that allowed for the first time to obtain a constant flow of electric current and is considered the first electric battery in history. Developed in Italy -
Brothers John Watkins and Jacob Brett laid the first international submarine telegraph cable between Great Britain and France in 1850, paving the way for global communication. Further development was made possible by William Montgomerie's discovery of gutta-percha, a natural latex that served as an excellent insulator for submarine cables. Mainly in Europe, linking Great Britain with France across the English Channel in 1850. -
A diode is an electronic component that allows electric current to flow in only one direction, acting as a "path" for electricity. The first diode, the vacuum diode, was invented by John Ambrose Fleming in 1904, based on the phenomenon discovered by Thomas Edison and the principle of thermionic emission. Its devepeloved in Britain -
The triode was invented by American engineer Lee De Forest in 1906. This device, also known as the Audion, was the first practical electronic amplifier and revolutionized electronics, enabling the development of technologies such as radio, telephone, television, and computers. Its developed in USA. -
The transistor was invented by American physicists John Bardeen, Walter Brattain and William Shockley at Bell Laboratories in December 1947. The first demonstration of the first point-contact transistor was made on December 23, 1947, although the invention was not published until the following year. It was developed at Bell Labs in Murray Hill, New Jersey, United States -

American engineers Jack Kilby and Robert Noyce developed the microchip in 1958, integrating individual transistors into a single circuit. Of the two, Noyce's microchip, patented in 1959, was the more popular. Were initially developed in the United States -
On August 28, 1958, Kilby assembled the first IC prototype using discrete components and received approval to implement it on a chip. Were developed in the United States. Integrated circuits are present in the vast majority of modern electronic devices, including computers, mobile phones, televisions, cars, medical equipment, and smart home appliances, as they are critical to their operation, size, and efficiency. -
Nanotechnology was not discovered by a single person, but rather emerged from the ideas of physicist Richard Feynman in 1959, who proposed the manipulation of atoms and molecules, being considered the "father of nanotechnology." It was the Japanese scientist Norio Taniguchi who coined the term "nanotechnology" in 1974 to describe the processing of materials at the nanometric scale. It was developed in the United States -
Marcian "Ted" Hoff formulated the architectural proposal in 1969. However, the implementation of the microprocessor only began in 1970 when Federico Faggin was hired by Intel, from Fairchild Semiconductor, to lead the project and to design the 4004 (1970-1971). It was developed in Silicon Valley, California, United States
