Logic gates are fundamental building blocks in computer science, used to perform logical operations and make decisions based on inputs. They are essential in creating digital circuits and are the backbone of modern computing. There are three main types of logic gates: AND, OR, and NOT. Each gate has a specific function and can be represented by a truth table that shows the output based on different input combinations. For example, an AND gate will only output a 1 if both inputs are 1, while an OR gate will output a 1 if either input is 1.NOT gates, on the other hand, simply invert the input.
These gates can be combined in various ways to create more complex logic functions. Logic gates are implemented using electronic circuits, with each gate having its own unique circuit design. For example, an AND gate can be created using two diodes and a resistor, while an OR gate can be made using transistors. These circuits are then combined to create larger circuits that perform more complex logical operations.Boolean algebra is a mathematical system used to express logic operations and simplify complex logical expressions. It uses binary variables and logical operators, such as AND, OR, and NOT, to represent logical statements.
