What is function of coupling?

coupling is a computer program, which is meant for the maintenance of the cohesion , coupling is inversely proportional to cohesion. When coupling and cohesion is combined then it acts as support to the high readability and maintainability of a computer program.

Why there should be low coupling and high cohesion in software design?

There should be low dependence and high interaction between the modules. The dependence should be low so that the module can work in absence of another module. So, there should be low coupling ad high cohesion in software design.

Why is highly coupled module difficult to unit test?

Unit test can be done within a single module Cohesion of a single module/component is the degree to which its responsibilities form a meaningful unit; higher cohesion is better. Someone had vague reference to decomposability here. Clarification? How about: 'Cohesion is inversely proportional to the number of responsibilities a module/component has.' Coupling between modules/components is their degree of mutual interdependence; lower coupling is better. size: number of connections between routines intimacy: the directness of the connection between routines visibility: the prominence of the connection between routines flexibility: the ease of changing the connections between routines A first-order principle of software architecture is to increase cohesion and reduce coupling. so having coupling in program is not correct reduce coupling in your program it will favour Unit testing......

What is the difference between a half coupling and a full coupling?

half coupling used to take branch from header ie: 2" header to 3/4' branch. where full coupling used to connect to straight pipe. ie: 2" to 2" pipe connection.


What is the difference between a socket and a coupling?

A socket is a female fitting that connects to a pipe or tubing, while a coupling is a device that connects two pipes or tubes together. Couplings can be either rigid or flexible, while sockets are typically fixed and do not allow movement.
