The following sequence of illustrations demonstrates the OR gate’s function, with the 2-inputs experiencing all possible logic levels. WebFrom the author: Interesting idea! It's true that a computer takes in binary data and outputs binary data. However, it does more than a logic gate. A logic gate is a device performing a Boolean logic operation on one or more binary inputs and then outputs a single binary output. Computers perform more than simple Boolean logic operations on input data, and …
