Scheme

Scheme is а graphical document, presentation, image, representation of something in a general way, simplified (for example, the scheme of the report); electronic device, comprising a plu-rality of components (integrated cir-cuit).

A circuit scheme is a graphical representation of an electrical circuit. A pictorial circuit scheme uses simple images of components, while a schematic scheme shows the components and interconnections of the circuit using standardized symbolic representations. The presentation of the interconnections between circuit components in the schematic scheme does not necessarily correspond to the physical arrangements in the finished device.
Unlike a block scheme or layout scheme, a circuit scheme shows the actual electrical connections. A drawing meant to depict the physical arrangement of the wires and the components they connect is called artwork or layout, physical design, or wiring diagram.
Circuit schemes are used for the design (circuit design), construction (such as PCB layout), and maintenance of electrical and electronic equipment.
