The transistor was first developed in 1947 in bell laboratories by a man named William Shockley. The transistor is an electrical component used in a circuit to control a large amount of current or voltage. Also known as the building block for the digital revolution, the transistor’s importance consists of controlling energy in electrical products.
A microchip can be found in many if not all electronic items around your house, from something as big as your car to something as small as your child’s electronic toy. A microchip is an interconnected electronic component such as transistors and resistors that are etched or imprinted on a tiny chip of semiconducting material. It was co-invented by Jack kilby from Texas instruments and James Noyce from Fairchild Semiconductor in the late 1950s.
