A block diagram is a diagram of a method where the main components or works are represented by cubes linked by lines that reveal the relationships of the cubes. They are heavily utilized in technology in hardware design, electronic design, software design, and process flow diagrams.

Block diagrams are typically used for higher degree, less comprehensive descriptions that are intended to clarify overall concepts without issue for the specifics of implementation. Contrast this with the design diagrams and design diagrams used in electric engineering, which show the implementation details of electrical components and physical construction.

To make an analogy to the map creating planet, a block structure is comparable to a highway map of an whole nation. The significant towns (functions) are listed but the small county roads and city roads aren't. After troubleshooting, this large level map is helpful in narrowing down and isolating where a problem or malfunction is.

A good instance of this is the function block structure, one of five programming languages defined in part 3 of the IEC 61131 (see IEC 61131-3) benchmark that's quite formalized (see formal system), with stringent rules to how diagrams must be assembled. Directed lines are utilised to connect input factors to block inputs, and block presses to output factors and inputs of other cubes.

Block diagrams rely upon the principle of this black box in which the contents are concealed from view either to avoid being distracted by the facts because the details aren't known. We understand what happens, we all know what happens, but we can not see the way the box does its work.

In electrical engineering, a design will often begin as a very higher level block diagram, getting more and more detailed block diagrams because the design progresses, finally ending in block diagrams comprehensive enough that each individual block can be easily executed (at which point the block structure is also a schematic diagram). This is referred to as top down style. [4] Geometric shapes are frequently utilized in the diagram to assist interpretation and describe meaning of this process or model. The geometric shapes are connected by lines to signify association and direction/order of traversal. Each engineering field has their own significance for each form. Block diagrams are employed in each discipline of technology. They're also a valuable source of theory building and educationally beneficial in non-engineering disciplines.

In biology there's a growing use of technology principles, techniques of analysis and methods of diagramming. There is some correlation between the block structure and what is named Systems Biology Graphical Notation. As it is there's use created in systems economics of the cube diagram technique exploited by controller engineering in which the latter itself is an application of control theory.

For example, a block diagram of a wireless is not anticipated to demonstrate each and every link and dial up and switch, however, the design diagram is. The schematic diagram of a radio doesn't show the diameter of every connection in the circuit board, however, the design diagram will not.

In process management, block diagrams are a visual vocabulary for describing activities within a complex system where blocks are black boxes that represent logical or mathematical operations which take place in order from left to right and top to bottom, but not the physical entities, like processors or radiators, that execute those operations. It's possible to create such cube diagrams and execute their functionality with technical programmable logic controller (PLC) programming languages. )
