Description
Hi everyone!. Welcome to gcequiz.com where in this quiz, we are going to be looking at Logic Gates. It has to do with the fundamental logic gates such as the AND gate, OR gate, NOT gate, NOR gate, NAND gate, and so on.
A logic gate is an idealized model of computation or physical electronic device that implements a Boolean function, performs a logical operation on one or more binary inputs, producing a single logic output. The implementation of logic gates is usually done using diodes and transistors. The diodes and transistors here act as switches, enabling the device to be switched from one state to another. With amplification, logic gates can be cascaded in the same way that Boolean functions can be composed, permitting the construction of a physical model of all of Boolean Logic. In modern practice, most logic gates are made from MOSFETs.
