Content coupling (high) Content coupling is said to occur when one module uses the code of another module, for instance a branch. This violates information hiding – a basic software design concept. Common coupling Common coupling is said to occur when several modules have access to the same global data.
An example of CSS code, which makes up the visual and styling components of a web page. Separation of content and presentation (or separation of content and style) is the separation of concerns design principle as applied to the authoring and presentation of content. Under this principle, visual and design aspects (presentation and style) are ...
Coupling refers to the degree of direct knowledge that one component has of another. Loose coupling in computing is interpreted as encapsulation versus non-encapsulation. An example of tight coupling is when a dependent class contains a pointer directly to a concrete class which provides the required behavior.
Bibliographic coupling, like co-citation, is a similarity measure that uses citation analysis to establish a similarity relationship between documents. Bibliographic coupling occurs when two works reference a common third work in their bibliographies. It is an indication that a probability exists that the two works treat a related subject ...
In electrical circuits sharing a common signal return path, electrical impedance in the return path creates common impedance coupling between the signals, resulting in crosstalk. [ 1 ] [ 2 ] Crosstalk is a significant issue in structured cabling , audio electronics , integrated circuit design , wireless communication and other communications ...
Efferent couplings signal outward. Abstractness (A): The ratio of the number of abstract classes (and interfaces) in the analyzed package to the total number of classes in the analyzed package. The range for this metric is 0 to 1, with A=0 indicating a completely concrete package and A=1 indicating a completely abstract package.
For example, screwdriver, scissors, knife, and hammer are all co-hyponyms of one another and hyponyms of tool, but not hyponyms of one another: *"A hammer is a type of knife" is false. Co-hyponyms are often but not always related to one another by the relation of incompatibility. For example, apple, peach and plum are co-hyponyms of fruit.
An improvised flexible coupling made of car tyre pieces connects the drive shafts of an engine and a water pump. This one is used to cancel out misalignment and dampen vibrations. Rotating coupling. A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is ...
