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.

Local-Area Networks

Local-Area Networks ( LANs ) are restricted to a small area. Such Networks may be established within a building. Computers that are part of Local-Area Networks are Personal Computers ( PCs ) or microcomputers. These Computers are connected to each other. Simple communication lines connect these Pers Networks bring people together. When people join  hands teamwork becomes possible. The structural composition of LANs simplifies teamwork. In other words, LAN hardware supports teams having similar processing requirements. LAN Computers readily support personalization of tasks allocated to professionals.  Office staff can work together and share information. This improves the efficiency of the entire workforce. It has been noted that here all the Networked Computers are Personal Computers. They are of equal capacity. Mostly LAN users have similar tasks. If situations allow, a user is independent to access any Computer to serve his purpose. LAN users can exercise the option of secu...

Computers - An Introduction

Computers are man made machines. They are made to work very fast. Working fast they can solve  big and small problems.  Modern science has given us these computers. They are very popular. Computers affect and change lives. They keep us happy.The happiness grows. Computers are quick and smart. Great problem solvers and simplifiers are our computers. They can do our work without stopping. Focus is on doing only what is needed. Not needed, not done.  Computers are  life-less servants. They cannot think or make decisions on their own. They are empowered to work. They are given each and every thing so that they carry out our orders. Orders are respected by computers. The manner in which computers work is wholly dependent on man.  The quality of service provided by computers is remarkable. They are loved by human beings. Computers are known for smart and quick service. Computers do not give wrong results. Correct answers are always given. Questions which are difficult...

Euclid's Algorithm

The Greatest Common Divisor ( GCD ) of  two numbers is a number. The number ( GCD ) causes division of the two numbers. This number ( GCD ) is the greatest number that is possible. This divisor partially forms the two numbers. Adding  the divisor successively may result in formation of the two numbers. One can note that when the divisor is the greatest, the division of the dividend is the sharpest. The division operation is very effective. When the Greatest Common Divisor of two numbers is considered, we think of a number that can cause division of both the numbers. Here the two numbers are unequal. The Greatest Common Divisor causes divisions of the two numbers differently. This is clear from the two different quotient values.  The GCD value is very interesting to note. It relates very well with the two numbers. The GCD of two even numbers is also an even number. The GCD of two odd numbers is an odd number. So, we can say that GCD is an abstraction of the two numbers in ...
