Question

Accepted Answer

Schematic is a diagrammatic representation of a circuit while layout is the physical representation of the same circuit.

Schematic shows the logical connections between components while layout shows the physical placement of components on the board.
Schematic is used for designing and testing the circuit while layout is used for manufacturing the circuit board.
Schematic is usually drawn using software like Eagle or Altium while layout is done using PCB design software like KiCAD or Allegro.
Schematic is easier to modify and update while layout requires more effort to make changes.
Schematic is usually in black and white while layout is in color to differentiate between layers and components.
