Logic gates form the foundation of digital circuits, allowing computers to perform various logical operations. Each gate performs a unique function, with basic types including:

• AND Gate: Outputs true if both inputs are true.
• OR Gate: Outputs true if at least one input is true.
• NOT Gate: Inverts the input (outputs true if the input is false and vice versa).
• NAND, NOR, XOR, XNOR Gates: Used for complex logical operations in digital circuits.

Logic gates are essential for designing circuits that handle data processing, making them foundational for computer architecture. Handwritten notes with detailed diagrams of each gate type help students visualize these operations.
