Differentiate between Component and Object.

Let us learn the concept of object and component.

Object

It is defined as a concept, thing or abstract with meaning.

Features

The features associated with object are as follows −

• State
• Operation
• Attributes
• Represent something real
• Provides an abstraction
• Self-contained
• Clearly defined.

Component

It can be defined as a collection of objects which provides a set of services to other systems.

For example − components include code which provides graphic facilities, network services, and a search set of tables in the database.

A component is a self-contained entity which provides functionality to its environment and also imports functionality from its environment using well defined and open interfaces.

The components that differ from objects are as follows −

• Components are self-contained.
• Provides service to other systems.
• Use interfaces to interact with other systems.

Differences

The major differences between component and object are as follows −

• A component is business-oriented (or) application-oriented. But an object is technology-oriented.

• A component is Standard-Based (or) Architecture-Based. But an object is Language-Based.

• A component provides services, whereas an object provides operations and methods.

• A component can be understood by everyone, whereas an object can be understood only by the developers.

• Component's main focus is on Abstraction and its secondary focus is on Encapsulation. An object's main focus is on Encapsulation and its secondary focus is on Abstraction.

• Components can be implemented in any programming language. Objects use only object-oriented programming language.

• Components have more static frequency of changing implementation. Object has a dynamic frequency changing implementation.

• Components depend on other components. Class depends on other classes using inheritance.
