The Boolean logic gates AND, OR and NOT comprise transistors, which are on/off switches wired together. Gates have one or two inputs but only one output, and they are wired in patterns that make ...

The output of the logic gate, calculated using the electronic properties of semiconductors, is the appropriate voltage from the desired Boolean operation. An "and" gate, for example, takes in two ...

Date: May 30, 2012 Source: Johns Hopkins Medicine Summary: Scientists have engineered cells that behave like AND and OR Boolean logic gates, producing an output based on one or more unique inputs.

OR gate In an OR gate, at least one input must be 1 for the output to be 1. This can be seen in the truth table for the OR gate. If input A OR input B is true, then output (Q) will be true.

GCSE OCR Boolean logic - OCR Why data is represented in binary form At the simplest level, computers are little more than a collection of transistors and circuits. They connect together to form ...
