A set of pre-built, standardized software components are made available to fit a specific architectural style for some application domain. Component Based Software Engineering encompasses two parallel engineering activities: domain engineering and component based development. This paper studies about Components, Component based development, its advantages, disadvantages and comparison of Component Based Software engineering with Conventional Software Engineering. based systems are easier to assemble and therefore less costly to build than systems constructed from discrete components. A Component is an independent executable entity. It does not have to be compiled before it is used with other components. The services offered by a component are made available through an interface and all the interactions take place through that interface. Advantages of Component based development are increased quality, accelerated development and reduced risk. 2. Component Interfaces The interfaces of a Component, as in Fig 1, are as follows: General Terms Component Based Software Engineering Provides Interface: defines the services that are provided by the component to other components. Keywords Requires Interface: defines the services that must be made available to the component to execute as specified. Component, reuse, Component based development, Component based software engineering. Requires interfaces Component Provides interfaces 1. Introduction A software component is a unit of composition with contractually specified .
