RULES OF COMMUNICATION

There is always some rules and regulation you have to follow everywhere. So like everywhere here in computer networking you also have to take care about some rules while communicating with any other workstation.

First we talk about Human Communication So let suppose have to tell something to his friends. So what is the minimum required thing they need.

1. First a sender (Pappu)
2. Communication Medium (Air)
3. A receiver (Arvind)

Because of a communication channel or medium one can transmit his or her message. Communication channel sometimes as simple as air and sometimes is full of many complications like in modem. Let take above example again, If Pappu send a message to Arvind via Computer network which is connected with a modem at the both end, so what the process is going on in communication channel.

After sending message from Pappu computer first conversion take place at sender side. (Modem convert digital signal to analog signal) so that telephone lines can transmit the data signal to other side. Then secondly data signal transmits and as soon as they reach at receiver end again analog signal are converted into digital signal so that computer can read the message. So here, in transmission channel is not simple as we seen in first case where Pappu simply tells a message to Arvind.

Now imagine, if there is more modem is present in a midway of data transmission so its make a transfer of data more complexity. Let suppose there is 10 modem present in between so apart from sender and receiver end 10 times more the conversion of signal to digital to analog and vice-versa take place.

Establishing the Rules

For establishing a network between two nodes there is some parameter which are essential to follow to make a secure and better network. These rules are mentioned below

1. An Identifier Sender and Receiver.
2. Both should be agreeing upon a method of communication.
3. Common language and grammar.
4. Speed and timing of delivery.
5. Confirmation of acknowledgement.

These rules also applicable in human communication, read them and think about it.
