Network: A Design

A Network is a design work. It is really a product that results from a careful design. We can have a Network of institutions. Or, we can have a Network of Computers. Both Networks ( either of institutions or of Computers ) are very carefully given concrete shape. 


In a Network of Computers, we have Computers as the nodes ( or nodal elements ). Although, there are other elements that make sense, Computers are most dominant, and are the centres of attraction. In other words, the Computers record the most impacting presence in a Computer Network. We can say that Computers are the eye-catching elements of Computer Network architecture.


In a Computer Network, Computers are not the only Network elements. Besides Computers, we have linking elements. Links ( or wire, or any other ) serve to connect nodal points, or Computers, we can say. 


Computers alone cannot make a Computer Network. It is linked Computers that form a Network. The idea of linking is central.


When a Computer Network is under discussion, the thought of Computer Hardware may visit us. It is clearly stated here that it is not necessary that all Computers in a Network have the same hardware. The architecture of Computers can be different. 


One Computer in a Network can have slow speed and it may be of low price. Another Computer in a Network can have high speed. The high speed Computer may cost high. The low-speed-low price, and high-speed-high-price Computers belong to two different hardware categories.


Indeed, Computer Networks are lenient about the type of hardware that is employed in making Computer units.


It is to be noted that a Computer, within a Computer Network, cannot communicate with other Computers that are not part of the given Computer Network.


It can be concluded that a Network enables communication. But we must also say that a Network also establishes a communication boundary. If a Computer wishes  to communicate, it can do so within the Network boundary. The world beyond the Network boundary is unavailable, we can say.

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...
