A component represents a modular part of a software system that encapsulates (hides) its contents, exposes public interface for provided services, and which is replaceable within system with equivalent or conformant components.
A component defines its behavior in terms of provided and required interfaces (potentially exposed via ports.) Internals of component are hidden and inaccessible other than as provided by its interfaces.
Larger pieces of a system's functionality may be assembled by reusing components as parts in an encompassing component or assembly of components, and wiring together their required and provided interfaces.

What does UML mean?
UML stands for Unified Modeling Language. It is a modelling language in software, designed to provide a standard way to visualize the design of a system.

How do you draw uml class diagram of banking loan system?
UML diagrams are generally produced by electrical engineers and require a thorough knowledge of UML and the Java programming language. Drawing such a diagram is a project given to students in electrical engineering classes.
What is the history of Unified Modeling Language?
OverviewThe Unified Modeling Language (UML) is used to specify, visualise, modify, construct and document the artifacts of an object-oriented software intensive system under development.[1] UML offers a standard way to visualize a system's architectural blueprints, including elements such as:actorsbusiness processes(logical) componentsactivitiesprogramming language statementsdatabase schemas, andreusable software components.[2]UML combines best techniques from data modeling (entity relationship diagrams), business modeling (work flows), object modeling, and component modeling. It can be used with all processes, throughout the software development life cycle, and across different implementation technologies.[3] UML has synthesized the notations of the Booch method, the Object-modeling technique (OMT) and Object-oriented software engineering (OOSE) by fusing them into a single, common and widely usable modeling language. UML aims to be a standard modeling language which can model concurrent and distributed systems. UML is a de facto industry standard, and is evolving under the auspices of the Object Management Group (OMG). OMG initially called for information on object-oriented methodologies that might create a rigorous software modeling language. Many industry leaders have responded in earnest to help create the UML standard.[1]UML models may be automatically transformed to other representations (e.g. Java) by means of QVT-like transformation languages, supported by the OMG. UML is extensible, offering the following mechanisms for customization: profiles and stereotype. The semantics of extension by profiles have been improved with the UML 2.0 major revision.
What is stereotype in UML?
Stereotype is a profile class which defines how an existing UML metaclass may be extended as part of a UML profile. Profiles allow lightweight extension of the standard UML by defining custom stereotypes, tagged values, and constraints for different:platforms (such as J2EE or .NET), ordomains (such as real-time or business process modeling).In other words, if existing UML metaclasses are not good enough, you can add your custom stereotypes by modifying standard UML metaclasses.
