Question

Classes communicate with one another via:

• A. processed information
• B. Interfaces
• C. messages
• D. coupling

Answer 1

Ans : $C$) Messages.

Information processing is the manipulation of data to produce useful information. Such information is called $processed \space information$.

$Interfaces$ are tools and concepts that technology developers use as points of interaction between hardware and software components. 

The classes communicate via $message\space passing$ mechanism in Object Oriented Programming.

$Coupling$ is the degree of interdependence between software modules; a measure of how closely connected two routines or modules are; the strength of the relationships between modules.
