Software components provide interfaces, which establish communication among different components

  - An individual software component is a software package, a web service, a web resource, or a module that encapsulates a set of related functions (or data).
  
  - All data and functions inside each component are semantically related (just as with the contents of classes) as all system processes are placed into separate components so that.
  
  - Components are modular and cohesive because of this principle.
  
  - The system-wide co-ordination is done by the components that communicate with each other via interfaces.
  
  - When services are offered by a component to the rest of the system, it adopts a provided interface that specifies the services that other components can utilize, and how they can do so.
  
  - This interface is seen as a signature of the component - the client does not need to know about the inner workings of the component (implementation) in order to make use of it.
  
  - The result of this principle is that components are referred to as encapsulated.
  
  - Whenever a component needs to use another component in order to function, it adopts a used interface that specifies the services that it needs.
