10 Questions
What is a logic gate?
A logic gate is an idealized or physical device that performs a Boolean function, a logical operation performed on one or more binary inputs that produces a single binary output.
How are most logic gates made in the present day?
Most logic gates are made from MOSFETs (metal–oxide–semiconductor field-effect transistors).
What are the different methods of building logic gates mentioned in the text?
The different methods mentioned include diodes, transistors, vacuum tubes, electromagnetic relays with relay logic, fluidic logic, pneumatic logic, optics, molecules, acoustics, and even mechanical or thermal elements.
How can logic gates be cascaded?
With amplification, logic gates can be cascaded in the same way that Boolean functions can be composed, allowing the construction of a physical model of all of Boolean logic.
What is the primary way of building logic gates in the real world?
The primary way of building logic gates in the real world uses diodes or transistors acting as electronic switches.
