What a block diagram is.
A block diagram represents the major components of a system as labelled blocks. Lines or arrows show how signals, data, material or control move between those components.
It deliberately leaves out internal implementation details. Use it when the essential question is what the parts are and how they interact; use a schematic, wiring diagram or flowchart when you need electrical connections, physical routing or process logic.
