A logic gate is a fundamental electronic device that performs a basic logical function, such as an AND, OR, or NOT, on one or more binary inputs to produce a single binary output. These gates are the building blocks of digital circuits, forming the basis for more complex operations in computers and other electronics by processing and making decisions based on 0s (false) and 1s (true).

What they are

Electronic devices: Logic gates are physical circuits, often made with transistors, that control the flow of electricity.

Logical operations: They operate based on the rules of Boolean algebra, taking binary inputs and producing a single binary output.

Building blocks: Gates are the foundation for all digital circuits, from the simplest to the most complex.

How they work

Binary inputs and outputs: A gate receives one or more inputs, which are either a low state (0) or a high state (1), and produces a single output based on a specific logic rule.

Combining gates: Multiple gates can be connected together to create more complex circuits that perform sophisticated tasks, such as arithmetic and data storage.

Truth tables: The behavior of a logic gate is defined by a truth table, which lists all possible input combinations and their corresponding outputs.
