Network Protocol


Network Protocol is a set of rules ( guidelines ) to help movement of information on a network. These rules have been given the form of agreement. We are happy that an agreement has materialized to help communication. We are talking about Computer-to-Computer communication. 


Indeed Network Protocol lends a helping hand, when information exchange between Computers is performed. 

The Network Protocol is available in standardized form. Those interested have worked to provide ways to let Computers communicate. The work product called Protocol is available with us. It serves to benefit when the Protocol is accepted as a guideline by the Computers willing to communicate.

The rules specified by Network Protocol serve to guide. It is very essential to follow the guidelines. The follow up  of  Network Protocol guarantees successful communication. 

Yes, the success of Computer-to-Computer communication is determined by the Protocol follow up. The Computers that communicate obey the Network Protocol. Thus, transfer of information becomes successful.

Network Protocol is very important. If Computers do not obey the Network Protocol, these Computers cannot communicate with each other. In the absence of Protocol  Computers become directionless. They do not know how to start communication. The process of communication fails to start.

In fact, Data Communication is difficult to imagine in the absence of Network Protocol.

The Focus of Network Protocol:

_________________

1 ) Size of Information:

Size of information is expressed as a number of bytes. Network Protocol clearly states the  size of information that is suitable for Computer-to-Computer communication.  The size of information may be different for different cases.


2 ) End-Point of Information:

If there is a transmitter, a receiver has to be there. Transmission has no meaning without a receiver. Network Protocol helps us to suitably select the receiving end. Transmitted information finally goes to the receiver. The receiver suitably keeps the information. Information available with the receiver is in the original form.



3 ) Structure of Information:

Communication is not possible if plain information is used for transmission purposes. Information that we commonly use ( called plaintext ) is suitably changed for communication. 

Network Protocol determines the structure of information that is to be used for communication. Transformation of information is performed before communication. This transformation is specified by Network Protocol.

4 ) Order of Information: 

Information in ordered form is meaningful. Communication process may change the order of information. Requirement of delivery of ordered information is felt. This requirement is fulfilled by Network Protocol.


5 ) Error Management:

Communication activity carries a risk. There is a risk of that  information may become unsuitable when it is on the way to receiver. Information becomes unsuitable when it contains errors. Errors reduce the worth and may turn the information to become useless.  Network Protocol responsibly checks the occurrences of errors in the content.

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...
