Objects which are packaged piece of code that can be accessed by remote clients via method invocations . Objects are used to put together complex client server information systems simply by assembling and extending reusable software components. The components are pre assembled class libraries where all components work together.

Benefits of Distributed objects :

1.   Data and business logic can be located any where
2.   Distributed objects interoperate along networks
3.   Each receiving object will react differently to the message based on its object type.
4.   Distributed objects allow us to create the application from parts.

Distributed Components :
 

A component is an object that is not bound to a particular program , computer language or implementation. The driving force which made them to develop the components are Time constraints and to make the various operating systems to interoperate. The independent software vendors find it difficult to develop a standard to interoperate.

Examples of components are OpenDoc, OLE , CORBA .

Components rescue

1. Small developers and independent software vendors to reduce their costs and cuts the barriers and smooth integration between applications

2. large developers and Independent software vendors components to create enterprise wide client server applications in record time . It provides higher reliability and easy to test.

Marketing people who will use the components in specific methods instead of specific markets of selling statement by statement and they can produce it in rock bottom prices.
