Computer
The inevntor was Charles Babbage in 1822. Computers work through a maze of microscopic transistors that react to electrical impulses that pass through their circuits and that have only two positions, which correspond to the numbers used in the binary system, zeros and ones. -
Telegraph
The inventor was Samuel Morse in 1832. The telegraph works through a previously arranged metal cable, it was possible to establish contact by sending different downloads following a code and, later, translating said signals alphabetically following the same code. -
Telephone
The inventor was Antonio Meucci in 1854. The telephone works through a membrane that vibrates with the voice, touching a piece of iron. When the membrane and the piece of metal came into contact to vibrate, an electromagnet located next to it varied its magnetic field, inducing an electric current. -
Radio
The inventor was Guigliermo Marconi in 1897. The radio works through a transmitter that records the information it wants to transmit in the form of an electrical signal. The transmitting antenna then converts this signal into an electromagnetic wave so that it can travel through space without the need for wires. -
Television
The inventor was John Logie Baird in 1923. How does television work? The tube that televisions have transforms the electrical signal it receives into the image we see on the screen. It generates an electron beam, the intensity of which is modulated by the deflection coils, which is focused and accelerated to produce a point of light on the screen. -
Tablet
The inventor was Alan Kay in 1968. Tablets are electronic devices that are made up of a touch screen, on the back of which there are several components that allow it to function, without the need for a physical mouse or keyboard. -
Telephone
The inventor was Martin Cooper in 1973. How cell phones work? Cell phones work by sending and receiving signals to cell phone towers (base stations) using RF waves.
