Summarizing logic gates with truth tables.What are logic gates? Circuits that compare!.Machine that's capable of basic mathematical "reasoning." Put lots of logic gates together and you make a In the same way, a microscopic logic gate is a barrier inĪn electronic circuit that can let electricity through or stop itįlowing altogether. Photo: A gate can keep you out or let you Subtract, multiply, and divide using nothing butĬalculators and computers do this using cleverĬalled logic gates. Switching on a transistor stores a number one switching it It's easy to store binary numbers simply by switching transistors onĪnd off. Last updated: July 11, 2021.Ĭalculators and computers store decimal (0–9) numbersĪs long strings of zeros and ones in a form called binary code.Įach number is stored using microscopic electronic switches called transistors.
