To create an analogy to the map which makes world, a block structure is very similar to a highway map of an entire nation. The major cities (serves ) are listed but the small county roads and city roads are not. When troubleshooting, this elevated degree map is useful in narrowing down and isolating in which a problem or mistake is.

Block diagrams are generally used for higher level, less comprehensive descriptions that are intended to describe overall concepts without consideration for the details of implementation. Compare this with the design diagrams and layout diagrams used in electrical engineering, which reveal the implementation details of electric components and physical structure.

In biology there is an increasing use of engineering fundamentals, techniques of research and ways of diagramming. There's a similarity between the block diagram and what is called Systems Biology Graphical Notation. Since it is there's use made in systems biology of this block structure technique harnessed by control technology where the latter itself is an application of control theory.

In process management, block diagrams are a visual language for describing actions within a complex system in which cubes are black boxes which represent mathematical or logical operations which take place in order from left to right and top to base, although not the physical entities, such as processors or radiators, that perform these operations. It's likely to create such cube diagrams and execute their functionality with technical programmable logic control (PLC) programming languages.

An example of that is that the function block diagram, among five programming languages described in part 3 of the IEC 61131 (see IEC 61131-3) benchmark that's quite formalized (see proper system), with stringent rules for how diagrams are to be assembled. Directed lines have been utilized to link input variables to block input signal, and block outputs to output factors and inputs of other blocks.

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

A block diagram is a diagram of a system in which the main components or works are represented by cubes joined by lines that reveal the connections of the blocks.

For example, a block diagram of a wireless is not anticipated to show each and every link and dial and switch, but the design diagram is. The schematic diagram of a wireless doesn't show the width of each connection from the circuit board, however the layout diagram does.

In electrical engineering, a style will often start as a very high level block structure, becoming increasingly more detailed block diagrams because the design develops, eventually ending in block diagrams detailed enough that every individual block is readily implemented (at which point the block structure will be also a schematic diagram). This is referred to as top down style. [4] Geometric shapes are frequently utilised in the diagram to assist interpretation and clarify meaning of the process or version. The geometric shapes are linked by lines to indicate association and direction/order of traversal. Each engineering discipline has their own meaning for every form. Block diagrams are used in every discipline of technology. They're also a valuable source of concept building and educationally valuable in non-engineering disciplines.
