They are used to describe a certain combination of inputs and outputs that can be used to make decisions based on the input signals.
Logic gates are built with transistors and other basic components, and can be used to create more complex circuits and systems. Logic gates are primarily used to control the flow of electrical current.
They can be used to check the validity of information, for example, to determine whether the information entered into a computer is valid or not.
Logic gates can also be used to perform arithmetic operations, such as addition and subtraction. Furthermore, logic gates can be used to control the flow of power, such as turning a light on and off.
Logic gates are classified into two main categories: combinational logic and sequential logic.
Combinational logic gates take one or more inputs and produce an output based on the input, while sequential logic gates take an input and produce an output based on the current state of the logic gate.
