Thomas Alva Edison (1847 to 1931) was an American inventor and businessman who ran some of the first industrial research laboratories. His teams developed the phonograph, a practical system of incandescent electric lighting and an early motion picture camera. He is also remembered for turning invention into an organized, team-based business. Early life of Thomas

A touchscreen is a display that also senses where a finger or stylus touches it, so a person can control a device by pressing, tapping or swiping directly on the image. It pairs a screen, such as a liquid crystal display or an OLED panel, with a sensing layer that reports the position of each
A display that also detects the position of a finger or stylus touching it, letting people control a device by pressing directly on the image.
A transformer is an electrical device that transfers energy between two or more circuits through electromagnetic induction, typically used to increase or decrease voltage without changing the frequency of the alternating current passing through it. Transformers are essential throughout electrical power systems, stepping voltage up for efficient long-distance transmission and back down to safe levels
An electrical device that transfers energy between circuits through electromagnetic induction, raising or lowering voltage.
A transistor is a small semiconductor device that can amplify an electrical signal or switch it on and off. It was demonstrated at Bell Telephone Laboratories in New Jersey in late 1947, and its inventors received the 1956 Nobel Prize in Physics. Transistors replaced vacuum tubes in most electronics and are the basic building blocks
A small semiconductor device that amplifies or switches electrical signals, first demonstrated at Bell Laboratories in 1947.
