COM: Component Object Model

COM is an abbreviation of the "Component Object Model". It is a system of the process of Microsoft parameter that describes the unique features of a binary-interface standard for interchanging code between systems, to make possible inter-process communication object formation in a vast array collection of programming languages.

Some of the Microsoft technologies and substructures, which are the foundational source of COM comprise:

  • Browser Helper Object
  • DCOM
  • OLE Automation
  • Direct X
  • Windows Runtime

COM History

  • In 1991, Microsoft launched Visual Basic Extensions (VBX) with Visual Basic 1.0 that enables objects to be with clear and vividly precise fine aspects by means of a visual form positioned in a type of structure and controlled by attributes and system of processes.
  • In 1993, Microsoft launched COM for software modules.
  • In 1996, Microsoft expanded COM with DCOM to operate all over the network.

Advantages of COM

  • It encourages and supports the reusability of code in which standard classes are generally reprocessed in a similar application other than these classes not to be used without difficulty simply in other additional applications.
  • Generally, two components that are coded by using two different programming languages cannot make communicate with each other but in the case of COM, it consists of the required and basic system of the method for its components to make communicate with each other.
  • It encourages and supports software development on the basis of the component resource.
  • It encourages and supports Object-oriented programming (OOP), whose most significant characteristics are encapsulation, polymorphism, and inheritance.
  • COM component can be located anywhere in the user's computer and also on any other additional computer, associated with the same network, which facilitates the COM in accessing the components carried by different types of systems on the same network.
