First computer
A computer is a machine that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming. Computers are used as control systems for a wide variety of industrial and consumer devices. -
First artificial satellite
In the context of spaceflight, a satellite is an object that has been intentionally placed into orbit. These objects are called artificial satellites to distinguish them from natural satellites such as Earth's Moon. On 4 October 1957 the Soviet Union launched the world's first artificial satellite, called Sputnik 1. -
Electronic chip
Electronic circuit made of semiconductor material, especially silicon, in the shape of a tiny cube, which, combined with other components, forms a more complex integrated system and performs a specific electronic function. -
LED diode
A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor -
Email
Electronic mail, a system that allows the exchange of messages between different computers interconnected through a network. -
Mobile phone
Is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area. -
Windows operating system
Microsoft Windows, commonly referred to as Windows, is a group of several proprietary graphical operating system families, all of which are developed and marketed by Microsoft. Each family caters to a certain sector of the computing industry. -
Flat-screen plasma display, Fujistu

Hybrid vehicles
It is when it is powered by two engines that can be of different nature: for example, an internal combustion engine and an electric one. -
Optical mouse
An optical mouse is a computer mouse which uses a light source, typically a light-emitting diode (LED), and a light detector, such as an array of photodiodes, to detect movement relative to a surface. -
Wi-Fi
Wi-Fi Is a family of wireless network protocols, based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access. Wi‑Fi is a trademark of the non-profit Wi-Fi Alliance, which restricts the use of the term Wi-Fi Certified to products that successfully complete interoperability certification testing
