A "schematic" is a simplified representation of a system, process, or concept, often used in fields like engineering, electronics, and architecture. It visually outlines the components and their relationships, making complex information easier to understand. Schematic diagrams can include symbols, lines, and labels to convey how different parts interact. In electronics, for example, a schematic diagram shows how various components like resistors, capacitors, and transistors are connected in a circuit. This helps engineers and technicians troubleshoot issues or design new devices by providing a clear overview of the circuit's layout and functionality.
