The COM Model



Software Industry takes pride in developing standard practices. When a model is designed, many of our goals become simple. 


The actual design of Software Components is guided by a standard model, i.e., COM ( Component Object Model ). Each and every step of Software Component design refers to the COM model. First the model is constructed. Once the model is in place, the detailed design is started, and the actual software Component is born. Till the end of Component design, and even after, the model of the Component serves the Component development and onward activities. The 'Component Model', or 'Component Object Model' ( COM ) lays stress on:


  1. Platform Independence: The model serves the purpose of being neutral to different kinds of systems. This kind of neutrality of COM is very promising. It leads to increased development activity, and thus promotion of software industry's interests. We mean the Component Model is  applicable to a variety of Operating Systems ( OSs ) and hardware platforms, as indicated by Platform Independence. Thus, COM has set the ball rolling and so heightened development in the software field has been around.



  1. Resource Sharing: The model of the 'Component' is used as reference. The model resource is shared by developers to make concrete software 'Components' to suit customer requirements.The model is of great help, and is central to generation of Component code.


  1. Standardization: The model is itself a standard. Also, standard software practices are utilised in  shaping up COM. Also, there are COM oriented software conventions promoting adoption of standard practices by the software industry. The 'Component Model' goes a long way to address the issue of standardization of model making.


  1. Risk Management: The model is constructed first. The working model is miniaturised. Models are tested, so that there is no way for error to occur onwards. We can say that COM is a forward looking Software Model. Use of 'Component Model' means sound risk management.


  1. Cost Estimation: The Component Model' is very clear about how things  in the domain of development are to come before the developers. Many development issues are known in advance. So, cost estimates are very close to reality.

Interface Message Processor ( IMP )

Interface Message Processor ( IMP ) is a special purpose Computer. The Processor plays a vital role in Host-to-Host communication. IMP is placed between Host Computers.  IMP helps Hosts to exchange information. IMPs ( Interface Message Processors ) form a group. The group dedicates itself towards reliable transmission of Packets. _________________________ Note: An Interface Message Processor can be supposed to have a face. Firstly this supposed face of IMP is in the direction of the first Host, which sends the  message. Secondly, this face is turned towards the other Host.  Now, the IMP,  with its face turned around, communicates with this other Host.  Transformed message from IMP is communicated to this Host. __________________________ Message ( a piece of information ) sent from the Host ( source of information  ) is transformed into Packets. Transformation of the message into Packets is performed by an IMP. These Packets are forwarded to the receiver H...

Understanding Distribution

Distributed presence means that more than one object is there. Also, these objects are situated at more than one location.  One object may establish communication with another object. The first object may deliver some message. The message can be received by another object. It can be said that object distribution is successful, as one object has succeeded in delivering a message. The second object has successfully received the message. Two objects are at a distance. Communication brings them closer. The successful communication has served to highlight that the idea of distribution is meaningful. Distribution helps exchange of information. Many different objects can form a group.  Two groups can occupy different locations.  It may happen that at a particular location there are several objects. But, all these objects talk among themselves.They talk among themselves and make things happen.  There is a resultant of this talk process. All the communicating objects  at...

Message Switching

Message is a piece of information. Switching means movement.  In a Network there are a number of nodes. Nodes are vital junctions of a Network. Message Switching means transmission from one node ( one point ) of a Network to another node ( another point ). So, transmission is from point to point. Transmission from one point to another point is a single hop ( jump ). Message Switching means switch over of a Message. In one step of Message Switching,  Message switches over from one node to another.  The two nodes involved in a Switching operation are on the same Network. It cannot be that the beginning node ( source node) is on one Network and the second node ( sink node ) is on a different Network. In a point to point ( one junction to another junction ) transmission, a Message travels a part of its journey. Message moves from previous point to next point. The Network is Point-to-Point Network. A Switching activity means movement of a message. Indeed, the Message has mov...
