block diagram
Component connection map
A block diagram is a simplified visual representation of a system, process, or program that uses labeled rectangles (blocks) connected by lines or arrows to show relationships and flow.
Engineers and technical writers use block diagrams to illustrate how components interact without getting into detailed circuitry or code.
The block diagram showed how data moved from input through processing to output.
Unlike flowcharts, which emphasize decision points and sequences, block diagrams focus on the functional units themselves and their connections.
